Asian Art Museum Visit and Assignment
On the first Sunday of every month, admission to the museum’s permanent collection is free. On other days, your student ID will get you discounted admission. ($10) I’d recommend spending at least two hours there whenever you go, but if you get “museum fatigue,” take a break, have some tea, come back later.
The Museum has a wonderful permanent collection of Chinese art. You are only required to go once this semester, but I hope you’ll want to go more than once. Make sure to see the small gilded Buddha, one of their most famous pieces, and the bronze rhinoceros. Their jade collection is also famous. And look at whatever paintings they have out at the moment to see the possible formats: hanging scroll, hand scroll, album paintings. Of course, if you have time, the rest of the museum—the Indian, Southeast Asian, Tibetan, Japanese, Korean, and Mongolian art-- is also wonderful.
Your assignment is to find TWO works of art in the China collection that you like. Describe them briefly and specifically, including both their similarities and their differences. For example, they may be in different media (bronze, painting, jade, etc) or from different periods, or about different subjects. Please include photographs, but don’t rely on the pictures in what you write. Instead, create a word picture of each work. Then explain (1) why you chose these particular pieces and (2) what you learned about Chinese civilization from them. One page total, about 300 words. Please scan and upload this and YOUR MUSEUM TICKET to the iLearn link. DUE ANY TIME DURING THE SEMESTER. GRADING IS CR/NC. THIS COUNTS FOR 5% OF YOUR GRADE.
If this assignment is a hardship for you because of money, work or family responsibilities, please consult me and I’ll figure out an alternative for you.

This document describes the process of meiosis through an activity where students arrange colored pipe cleaners to represent chromosomes. Meiosis reduces the chromosome number in cells from the diploid to haploid number in two cell divisions. In the first division, homologous chromosome pairs separate so the resulting cells have half the original number. The second division is like mitosis, forming four cells each with the haploid number of unpaired chromosomes. Meiosis ensures genetic variation between gametes so offspring receive a unique combination of genes from each parent.
This document discusses cellular reproduction through mitosis and meiosis. It provides objectives about explaining the cell cycle, defining key terms, comparing asexual and sexual reproduction, and the roles of meiosis in sexual reproduction. The main topics covered are the cell cycle, mitosis, meiosis, gamete formation, fertilization, and how meiosis and sexual reproduction generate genetic variation in offspring. Key terms defined include chromosome, gene, haploid, diploid, homologous pairs, and sister chromatids.
The document provides an overview of key concepts in biology related to genetics and cellular reproduction. It defines the laws of segregation and independent assortment. It also describes dominant and recessive traits, multiple alleles, polygenic traits, mitosis, meiosis, the cell cycle, and compares the key differences between mitosis and meiosis.

Activity
Cellular reproduction in Eukaryotes involves either mitosis or, in the case of sex cells, meiosis. Mitosis involves the reproduction of a cell into two identical daughter cells. Meiosis, however, is a reduction division where a parental diploid cell produces four haploid gametes. Upon fusion, two haploid gametes (in humans the sperm and the egg) will result in one diploid zygote. In this activity you will track chromosomes through meiosis using colored beads.

Lab 4: Meiosis

Introduc on
Meiosis only occurs in organisms that reproduce sexually. The process generates haploid (1n) cells
called gametes (sperm cells in males and egg cells in fe-
males), or spores in some plants, fungi, and pro sts, that
contain one complete set of chromosomes. Haploid cells
fuse together during fer liza on to form a diploid cell with
two copies of each chromosome (2n).
Genes are the units of heredity that have speciÞc loci
(loca ons) on the DNA strand and code for inheritable
traits (such as hair color). Alleles are alterna ve forms of the same gene (brown vs. blue eyes). Homol-
ogous chromosomes contain the same genes as each other but o en di erent alleles. Non-sex cells
(e.g. bone, heart, skin, liver) contain two alleles (2n), one from the sperm and the other from the egg.
Mitosis and meiosis are similar in many ways. Meiosis, however, has two rounds of division—meiosis I
and meiosis II. There is no replica on of the DNA between meiosis I and II. Thus in meiosis, the parent
cell produces four daughter cells, each with just a single set of chromosomes (1n).
Meiosis I is the reduc on division– the homologous pairs of chromosomes are separated so that each
daughter cell will receive just one set of chromosomes. During meiosis II, sister chroma ds are sepa-
rated (as in mitosis).
Concepts to explore:
Meiosis
Diploid cells

MITOSIS AND MEIOSIS
One of the tenets of cell theory is that all cells come from pre-existing cells. All individual
organisms begins with one cell, and yet in multicellular organisms the number of cells in the
adult may be in the trillions. This requires cells to repeatedly divide during the life of an
organism.
The average adult human body is made up of about 37 trillion cells. Of these, approximately 50
billion are fat cells and 2 billion are heart muscle cells. By the time you finish reading this
sentence, 50 million of your cells will have died and been replaced by others. Human cells are
estimated to divide nearly 2 trillion times every day. Amazingly, humans contain at least 10
times as many bacteria cells as human cells. The 100 trillion bacterial cells are much smaller
than human cells and have a faster generation time.
Mitosis and meiosis are two processes that produce new cells through cell division, which occurs
as a part of the cell cycle. The new “daughter” cells produced by these processes are quite
different because they have different purposes. These differences occur because the processes
have several key differences as outlined in the video lecture. You will be doing several lab
activities examining mitosis and meiosis and what can happen if problems occur during these
cell division processes.
Why are we doing this lab?
1. To gain a better understanding of the mitotic and meiotic processes of cell division that
occur in humans and all other animals.
2. To examine how issues in mitosis and meiosis can lead to diseases and disorders in
humans.

This document discusses meiosis and how it differs from mitosis. Meiosis results in four haploid daughter cells rather than two diploid cells. It allows for genetic recombination through processes like synapsis, crossing over, segregation and independent assortment during prophase I and anaphase I. Meiosis is important for sexual reproduction as it generates gametes like sperm and eggs that each contain half the normal number of chromosomes.
Experiment 2 The Importance of Cell Cycle Control Some environm.docxSANSKAR20
Experiment 2: The Importance of Cell Cycle Control
Some environmental factors can cause genetic mutations which result in a lack of proper cell cycle control (mitosis). When this happens, the possibility for uncontrolled cell growth occurs. In some instances, uncontrolled growth can lead to tumors, which are often associated with cancer, or other biological diseases.
In this experiment, you will review some of the karyotypic differences which can be observed when comparing normal, controlled cell growth and abnormal, uncontrolled cell growth. A karyotype is an image of the complete set of diploid chromosomes in a single cell.
Materials
*Computer Access
*Internet Access
*You Must Provide
Procedure
1. Begin by constructing a hypothesis to explain what differences you might observe when comparing the karyotypes of human cells which experience normal cell cycle control versus cancerous cells (which experience abnormal, or a lack of, cell cycle control). Record your hypothesis in Post-Lab Question 1.
Note: Be sure to include what you expect to observe, and why you think you will observe these features. Think about what you know about cancerous cell growth to help construct this information
2. Go online to find some images of abnormal karyotypes, and normal karyotypes. The best results will come from search terms such as “abnormal karyotype”, “HeLa cells”, “normal karyotype”, “abnormal chromosomes”, etc. Be sure to use dependable resources which have been peer-reviewed
3. Identify at least five abnormalities in the abnormal images. Then, list and draw each image in the Data section at the end of this experiment. Do these abnormalities agree with your original hypothesis?
Hint: It may be helpful to count the number of chromosomes, count the number of pairs, compare the sizes of homologous chromosomes, look for any missing or additional genetic markers/flags, etc.
4. Take a picture of your results. Include a note with your name and date on an index card in the picture. Insert picture here.

The document discusses cell division and reproduction in humans. It describes the two types of cell division - mitosis and meiosis. Mitosis maintains the chromosome number and results in two daughter cells identical to the parent cell. Meiosis involves two cell divisions and reduces the chromosome number by half to produce gametes like eggs and sperm. The stages of each type of cell division are explained in detail, including the processes of DNA replication, chromosome condensation, separation of chromatids, and cytokinesis.
Mitosis is the process where a parent cell divides into two daughter cells with identical genetic material. It occurs in four stages: prophase, metaphase, anaphase, and telophase. In prophase, the nuclear membrane dissolves and spindle fibers form. In metaphase, chromosomes align in the middle. In anaphase, chromosomes separate and move to opposite poles. In telophase, nuclear membranes form around the separated chromosomes, forming two identical daughter cells. The final stage of cell division is cytokinesis, where the cytoplasm divides. In animal cells this occurs via cleavage furrow formation, while in plant cells it occurs via cell plate formation. Mitosis is important for growth, development, and reproduction.
1) Meiosis is a type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell. It occurs in two stages, Meiosis I and Meiosis II, resulting in four daughter cells each with half the chromosome number.
2) During Meiosis I, homologous chromosomes pair and crossover can occur, separating the parental chromosomes. This reduces the chromosome number from diploid to haploid.
3) Meiosis II then separates the sister chromatids, resulting in four unique haploid daughter cells that can fuse during fertilization.
The document discusses how cells reproduce through cell division processes like mitosis and meiosis. It explains that mitosis results in two identical daughter cells while meiosis produces four haploid cells through two cell divisions. The stages of mitosis and meiosis are compared, and meiosis is described as introducing genetic variation through crossing over during prophase I which provides an advantage over asexual reproduction.
1. The lab experiment involved using pop beads to simulate the phases of mitosis and meiosis in plant cell division. Students observed onion root tip cells under a microscope to identify the phases of mitosis.
2. Data was collected on the number of cells observed in each phase of mitosis and the percentage of time a cell spends in each phase was calculated. A line graph of the results was made.
3. Key differences between mitosis and meiosis were identified through the pop bead simulations and microscope observations, such as the number of resulting cells and chromosomes after each type of cell division.
This document provides instructions for a lab to observe mitosis in onion root tip cells. Students will examine prepared slides of onion root tips under a microscope to identify and count the number of cells in each stage of mitosis. This includes making a pie chart to calculate the relative duration of each mitotic phase. The hypothesis is that interphase will be the most commonly observed phase since cells spend most of their time in interphase.
This document contains a biology review with 10 questions covering topics of cell division, chromosomes, and mutations. The questions assess understanding of key concepts like independent assortment, fertilization, meiosis, karyotypes, chromosomal abnormalities, and genetic variation. Correct answers are not provided, rather the student is expected to show their work and explain their reasoning for questions involving calculations and comparisons of DNA content during cell cycle stages. The review covers foundational material relevant to inheritance, genetics, and prenatal testing.

This document describes the process of meiosis through an activity where students arrange colored pipe cleaners to represent chromosomes. Meiosis reduces the chromosome number in cells from the diploid to haploid number in two cell divisions. In the first division, homologous chromosome pairs separate so the resulting cells have half the original number. The second division is like mitosis, forming four cells each with the haploid number of unpaired chromosomes. Meiosis ensures genetic variation between gametes so offspring receive a unique combination of genes from each parent.
This document discusses cellular reproduction through mitosis and meiosis. It provides objectives about explaining the cell cycle, defining key terms, comparing asexual and sexual reproduction, and the roles of meiosis in sexual reproduction. The main topics covered are the cell cycle, mitosis, meiosis, gamete formation, fertilization, and how meiosis and sexual reproduction generate genetic variation in offspring. Key terms defined include chromosome, gene, haploid, diploid, homologous pairs, and sister chromatids.
The document provides an overview of key concepts in biology related to genetics and cellular reproduction. It defines the laws of segregation and independent assortment.

Activity
Cellular reproduction in Eukaryotes involves either mitosis or, in the case of sex cells, meiosis. Mitosis involves the reproduction of a cell into two identical daughter cells. Meiosis, however, is a reduction division where a parental diploid cell produces four haploid gametes. Upon fusion, two haploid gametes (in humans the sperm and the egg) will result in one diploid zygote. In this activity you will track chromosomes through meiosis using colored beads.

Introduc on
Meiosis only occurs in organisms that reproduce sexually. The process generates haploid (1n) cells
called gametes (sperm cells in males and egg cells in fe-
males), or spores in some plants, fungi, and pro sts, that
contain one complete set of chromosomes. Haploid cells
fuse together during fer liza on to form a diploid cell with
two copies of each chromosome (2n).
Genes are the units of heredity that have speciÞc loci
(loca ons) on the DNA strand and code for inheritable
traits (such as hair color). Alleles are alterna ve forms of the same gene (brown vs. blue eyes). Homol-
ogous chromosomes contain the same genes as each other but o en di erent alleles. Non-sex cells
(e.g. bone, heart, skin, liver) contain two alleles (2n), one from the sperm and the other from the egg.
Mitosis and meiosis are similar in many ways. Meiosis, however, has two rounds of division—meiosis I
and meiosis II. There is no replica on of the DNA between meiosis I and II. Thus in meiosis, the parent
cell produces four daughter cells, each with just a single set of chromosomes (1n).
Meiosis I is the reduc on division– the homologous pairs of chromosomes are separated so that each
daughter cell will receive just one set of chromosomes. During meiosis II, sister chroma ds are sepa-
rated (as in mitosis).

MITOSIS AND MEIOSIS
One of the tenets of cell theory is that all cells come from pre-existing cells. All individual
organisms begins with one cell, and yet in multicellular organisms the number of cells in the
adult may be in the trillions. This requires cells to repeatedly divide during the life of an
organism.
The average adult human body is made up of about 37 trillion cells. Of these, approximately 50
billion are fat cells and 2 billion are heart muscle cells. By the time you finish reading this
sentence, 50 million of your cells will have died and been replaced by others. Human cells are
estimated to divide nearly 2 trillion times every day. Amazingly, humans contain at least 10
times as many bacteria cells as human cells. The 100 trillion bacterial cells are much smaller
than human cells and have a faster generation time.
Mitosis and meiosis are two processes that produce new cells through cell division, which occurs
as a part of the cell cycle. The new “daughter” cells produced by these processes are quite
different because they have different purposes. These differences occur because the processes
have several key differences as outlined in the video lecture. You will be doing several lab
activities examining mitosis and meiosis and what can happen if problems occur during these
cell division processes.
Why are we doing this lab?
1. To gain a better understanding of the mitotic and meiotic processes of cell division that
occur in humans and all other animals.
2. To examine how issues in mitosis and meiosis can lead to diseases and disorders in
humans.

This document discusses meiosis and how it differs from mitosis. Meiosis results in four haploid daughter cells rather than two diploid cells. It allows for genetic recombination through processes like synapsis, crossing over, segregation and independent assortment during prophase I and anaphase I. Meiosis is important for sexual reproduction as it generates gametes like sperm and eggs that each contain half the normal number of chromosomes.

Experiment 2: The Importance of Cell Cycle Control
Some environmental factors can cause genetic mutations which result in a lack of proper cell cycle control (mitosis). When this happens, the possibility for uncontrolled cell growth occurs. In some instances, uncontrolled growth can lead to tumors, which are often associated with cancer, or other biological diseases.
In this experiment, you will review some of the karyotypic differences which can be observed when comparing normal, controlled cell growth and abnormal, uncontrolled cell growth. A karyotype is an image of the complete set of diploid chromosomes in a single cell.

Procedure
1. Begin by constructing a hypothesis to explain what differences you might observe when comparing the karyotypes of human cells which experience normal cell cycle control versus cancerous cells (which experience abnormal, or a lack of, cell cycle control). Record your hypothesis in Post-Lab Question 1.
Note: Be sure to include what you expect to observe, and why you think you will observe these features. Think about what you know about cancerous cell growth to help construct this information
2. Go online to find some images of abnormal karyotypes, and normal karyotypes. The best results will come from search terms such as “abnormal karyotype”, “HeLa cells”, “normal karyotype”, “abnormal chromosomes”, etc. Be sure to use dependable resources which have been peer-reviewed
3. Identify at least five abnormalities in the abnormal images. Then, list and draw each image in the Data section at the end of this experiment. Do these abnormalities agree with your original hypothesis?
Hint: It may be helpful to count the number of chromosomes, count the number of pairs, compare the sizes of homologous chromosomes, look for any missing or additional genetic markers/flags, etc.

CHILDERN AND ANXIETY
CHILDREN AND ANXIETY
The prevalence of anxiety disorders among children seems to be on the rise. Children are being treated for obsessive-compulsive disorder, for post-traumatic stress syndrome, and generalized anxiety disorders. Some authors have suggested that the world is a far more frightening and stressful place for children now than in previous generations. Recent historical events, such as the terrorist attack on the World Trade Center, the war in Iraq, and similar events that receive heavy media coverage, may present children with things to think about that previous generations did not experience. In addition, children are exposed to many more graphic images of violence and victimization in their media. These factors, plus the fact that their parents, teachers, and caregivers are also experiencing stressors, might contribute to children’s anxiety.

You must create a court system for the newly created state of Puerto.docxdavezstarr61655
You must create a court system for the newly created state of Puerto Rico. You are to work under the assumption that Puerto Rico has just been admitted as the 51st state and build your court system from the bottom up. To be certain you understand how courts are organized in other states, you must research at least three current state court systems, within the United States, and use those systems to create Puerto Rico’s system. Do not use Puerto Rico’s current system as one of your examples. You must describe your proposal for creating Puerto Rico’s municipal courts, major trial courts, appellate courts, and the state’s highest court. Include geographic jurisdictions.
You must also describe how judges will be chosen for each court and must discuss how judicial and attorney ethical standards will be structured and enforced. You should conduct basic research on Puerto Rico (size, geography, population, existing counties or municipios, etc.) to be certain your proposed system will actually work.
Remember to provide citations when you borrow some idea or structure from another state.
The body (not including cover page, works cited/bibliography, etc.) of the paper must be 10-12 pages in length, double spaced, using Times New Roman 12-point font. A works cited page or bibliography (depending on the citation system used) must be included. Submitting too many pages will have the same result as submitting too few pages.

You must complete an Electronic Presentation on Black Culture.docxdavezstarr61655
You must complete an
Electronic Presentation on Black Culture
. You will select and present on the significances of two works of black culture. The first work you select must be a work of African-American literature, poetry, music, fashion, dance, or some other cultural art form that was created and/or popularized by an
African American
during the time periods of the Harlem and Chicago Renaissances (1917-1949). Your second work of black culture must have been created and/or popularized by a black person (but not necessarily an African American) within YOUR lifetime. For example, if you were born in 1999, your second cultural selection needs to have been created by a black person between 1999 and the present. The two works you select to present do not have to share a cultural form (i.e. one work can be a poem and the other can be a song; one work can be a painting and the other can be a fashion trend). Nor do the two works have to share a particular theme. You may choose to do a compare-and-contrast type presentation. But, you do not have to. In presenting the works, you will need to provide background information on your chosen works (i.e. when where the works created; who created them or made them famous; and, what impact did the works have on the cultural landscape when and since they first appeared?). You will also have to briefly explain why you made those particular selections, and explain what you think each work tells people about the ways in which African-American/Black culture and experiences remained congruent and/or changed from the eras of the Harlem and Chicago Renaissances to the modern era. Moreover, your Electronic Presentation on Black Culture must be creative in both style and substance.
Your Electronic Presentation should have a run time of 7-10 minutes.
And, it must contain both audio and visual components.
When delivering your Electronic Presentation, you will serve as the professor for the class. So, give a Presentation that your temporary students (i.e. your classmates and Dr. Brown) will find to be both impressive and informative. The more creative, interesting, organized, and informative your Presentation is, the higher your grade will be. If your Presentation is disorganized, bland, lacks imagination, or does little more than echo information and ideas that have already been presented through the course texts, media, and PowerPoint lectures, you should not expect to earn a stellar grade on it.
Your presentation should add information, details, and/or perspectives that we did not cover in class. As such, I strongly recommend that you research and select cultural works that we did not discuss in class. In other words, avoid selecting a poem by Langston Hughes or a song we covered in class. Be more creative. Do more research. And, you should use and cite outside sources for the Electronic Presentation.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Asian Art Museum Visit and AssignmentOn the first Sunday of .docx
1. Asian Art Museum Visit and Assignment
On the first Sunday of every month, admission to the museum’s
permanent collection is free. On other days, your student ID
will get you discounted admission. ($10) I’d recommend
spending at least two hours there whenever you go, but if you
get “museum fatigue,” take a break, have some tea, come back
later.
The Museum has a wonderful permanent collection of Chinese
art. You are only required to go once this semester, but I hope
you’ll want to go more than once. Make sure to see the small
gilded Buddha, one of their most famous pieces, and the bronze
rhinoceros. Their jade collection is also famous. And look at
whatever paintings they have out at the moment to see the
possible formats: hanging scroll, hand scroll, album paintings.
Of course, if you have time, the rest of the museum—the Indian,
Southeast Asian, Tibetan, Japanese, Korean, and Mongolian art-
- is also wonderful.
Your assignment is to find TWO works of art in the China
collection that you like. Describe them briefly and specifically,
including both their similarities and their differences. For
example, they may be in different media (bronze, painting, jade,
etc) or from different periods, or about different subjects.
Please include photographs, but don’t rely on the pictures in
what you write. Instead, create a word picture of each work.
Then explain (1) why you chose these particular pieces and (2)
what you learned about Chinese civilization from them. One
page total, about 300 words. Please scan and upload this and
YOUR MUSEUM TICKET to the iLearn link. DUE ANY TIME
DURING THE SEMESTER. GRADING IS CR/NC. THIS
COUNTS FOR 5% OF YOUR GRADE.
