Describe the mechanisms of asexual reproduction in: Prokaryotes Protists Plants- Animals Solution Prokaryotes reprodue asexually by BINARY FISSION mehanism. In this the genetic material is replicated as same as the parent genome the cell devides in two parts and give rise to new progeny so no geneti diversity is formed. protists- they also reprodue asexually through binary fission, BUDDING In this new organism grow from the body of parent. PLANT- VEGETATIVE reproduction is the main asexual reproduction in which a plant part give rise of new plant same as the parent, such as growing tips of RHIZOME. ANIMALS- they also reproduce asexually through budding,fission,fragmentation.In case of stick inset, bees PARTHENOGENESIS our in whih unfertilised egg give rise to new individual it is a type of AGAMOGENESIS..

Reproduction

Rhia Mae Tepora

defined as a biological process in which an organism gives rise to young ones (offspring) similar to itself.  Asexual reproduction:  Offsprings produced by single parents.  Without involvement of gamete formation  Offsprings are genetically identical to their parentsCell division as a method of asexual reproduction as in Protista and monera.  Binary fission e.g. Amoeba, Paramecium.  Budding: e.g. yeast.  Asexual reproductive structures:  Zoospores: aquatic fungi, Chlamydomonas.  Conidia: Penicillium.  Bud: Hydra  Gemmules: sponges.  Vegetative propagation units in plant: (Vegetative propagules)  Runner, rhizome, sucker, tuber, offset, bulb.

While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.

Asexual vs sexual reproduction

ove doesn’t equal sex. It’s important to remember that asexuality is an umbrella term, and exists on a spectrum. Asexual people – also known as “Ace” or “Aces” – may have little interest in having sex, even though they desire emotionally intimate relationships. Within the ace community there are many ways for people to identify. Asexuality Chart Here are just a few common terms to explore: Demisexual: People who only experience sexual attraction once they form a strong emotional connection with another person. Grey-A: People who identify somewhere between sexual and asexual. Queerplatonic: People who experience a type of non-romantic relationship where there is an intense emotional connection that goes beyond a traditional friendship. Aces commonly use hetero-, homo-, bi-, and pan- in front of the word romantic to describe who they experience romantic attraction to. For example, a person who is hetero-romantic might be attracted to people of a different sex or gender, but not in a sexual way. Asexuality Blurry Do and Don't Say FAQ My friends talk about sex all the time, but I don’t feel any desire to be with someone in that way. Is it normal to not feel any sexual attraction towards other people? I am romantically attracted to boys and girls, but I don’t want to be with them physically. Can I be bisexual and asexual? I kissed my boyfriend for the first time and it was gross! Does this mean I am asexual? How do I tell my partner/the person I like that I am asexual? People are telling me that something is wrong with me now that I’ve come out as asexual. Even worse, some are saying that asexuality doesn’t exist. How can I help them understand me?

I l Show that if X has the discrete topology, then its only connected subspaces are point sets. Solution Let X have discrete topology. Any subset Y of X is the union of singletons , each of which is both open and closed (as X has discrete topology) So the maximal sets which cannot expressed as a disjoint union of open (closed) subsets are the singletons. Hence the connected components of X are the singletons..

In 2006 the CEO of Bear Sterns, James Caynes, received a compensation package of $34 million. The following year Bear Sterns cost $2.7 billion to the taxpayers. In 2006, the CEO of Lehman Brothers received a compensation package of $27 million. On September 15, 2008, Lehman Brothers filed for bankruptcy. The collapse of Lehman Brothers is seen by many as the key event that sparked the Global Financial Crisis. In 2006, the CEO of Citigroup, Charles Prince, received a compensation package of $25 million. Since then the stock price has fallen from $50 a share to $3.5 a share. The CEO of Countrywide Financial, Angelo Mozilo, did even better. His compensation package was $43 million. Angelo Mozilo and two other top executives were charged by the Security and Exchange Commission (SEC) with fraud. According to the SEC, from 2005 through 2007, Countrywide Financial engaged in an unprecedented expansion of its underwriting guidelines and was writing riskier and riskier loans, which these senior executives were warned might ultimately curtail the company\'s ability to sell them. Countrywide Financial was the third biggest originator of subprime mortgages and the nation\'s leader in subprime mortgage- backed securities. The tragedy is that these individuals did not make decisions that were in their companies’ best interest. Why? What went wrong? What caused the relation between the CEO and the stockholders to go so badly awry? Discuss Solution Leaders who lose their way are not necessarily bad people; rather, they lose their moral bearings, often yielding to seductions in their paths. Very few people go into leadership roles to cheat or do evil, yet we all have the capacity for actions we deeply regret unless we stay grounded. Leaders whose goal is the quest for power over others, unlimited wealth, or the fame that comes with success tend to look to others to gain satisfaction, and often appear self-centered and egotistical. They start to believe their own press. As leaders of institutions, they eventually believe the institution cannot succeed without them. While most people value fair compensation for their accomplishments, few leaders start out seeking only money, power, and prestige. Along the way, the rewards—bonus checks, newspaper articles, perks, and stock appreciation—fuel increasing desires for more. This creates a deep desire to keep it going, often driven by desires to overcome narcissistic wounds from childhood. Many times, this desire is so strong that leaders breach the ethical standards that previously governed their conduct, which can be bizarre and even illegal. Many leaders get to the top by imposing their will on others, even destroying people standing in their way. When they reach the top, they may be paranoid that others are trying to knock them off their pedestal. Sometimes they develop an impostor complex, caused by deep insecurities that they aren\'t good enough and may be unmasked. To prove they aren\'t impostors, they drive so.

How would a CFE devise a plan to prevent subsequent employee fraud? Solution ANSWER: Although the prevention of fraud is always less costly and more effective than fraud detection (and subsequent investigation), however unfortunately prevention is not always possible. This the reason, as CFE’s Certified Fraud Examiners (CFE) we must all be heavy promoters (and supporters) of client internal audit functions The CFE devise a plan to internal audit that includes the procedures to identify or prevent significant incomplete, inaccurate, or unauthorized transactions; unreliable financial reporting; deficiencies in safeguarding assets; and deviations from regulations, laws, and institutional policies. When effectively designed and implemented, internal audits gives directors and senior managers with timely information in regard to weaknesses in the internal control system and thus facilitating timely remedial action and prevent subsequent employee fraud. Each institution is required to have an internal audit function appropriate to the size and the nature and scope of the activities.

Hilary rode her horse for 8 miles until it was hurt.Then she walked back home to call a vet. She figures the horse wals twice as fast as she does. the whole trip took 4 hours, so how fast would Hilary have to walk? Solution The equation used in this problem is SpeedXTime=Distance We know that the entire trip takes 4 hours Let us designate x as the time that it takes the horse to travel 8 miles 4-x= is designated as the time it takes Hilary to walk back we also know the ratio of rate 2:1 Let us set up the equation (Distance/Time)=speed of the horse =8/x (Distance/Time)=speed of Hilary =8/4-x We need to make both sides of the eqation equal. In order to do this we need to multiply (8/4-x) by 1/2 since the horse is going 2x the speed of Hilary 8/x=(1/2)(8/4-x) Simplify by dividing 8 by 2 so that you get 8/x=4/4-x Cross multiply to get 8(4-x)=4x Use the distributive property 32-8x=4x Add 8x to both sides and get 32=12x Divide both sides by 12 x=1.33 hours it took the horse 4-x=2.67 hours it took Hilary 2.99 or 3 miles per hour To double check let\'s plug in values Speed(Time)=8 (3)2.67)=8.0 miles for Hillary The horse speed is 8/1.33=6.0 mph the horse is going 6/3 as fast as Hilary the answer is 2..

The assignment explores the resiliency of elders of (African American antic/Latino. Asian American Indian) or the status of older women in society compared to older men. Students will research the economic status, health, social supports, living situations marry of one of the special populations chosen by the student. They will also research specific cultural values and beliefs regarding life, acceptance of help, and death. Students are encouraged to use the text and at least 3 other reliable sources to gather information. Sources should be documented in APA style of referencing Length is 5 pages of content, double-spaced in 12 point font. Paper is due the 7th week of class and is worth so points. No late submissions will be accepted. The due date is Friday, February 24, by 11:00pm Central Start Date Due Date is Friday, February 24, by 11:00 pm central Time. Solution DIVERSITY RESEARCH ASSIGNMENT Age and Socioeconomic Status Socioeconomic status (SES) is often measured as a combination of education, income and occupation. It is commonly conceptualized as the social standing or class of an individual or group. When viewed through a social class lens, privilege, power and control are emphasized. Furthermore, an examination of SES as a gradient or continuous variable reveals inequities in access to and distribution of resources. SES is relevant to all realms of behavioural and social science, including research, practice, education and advocacy. SES Affects Our Society SES affects overall human functioning, including our physical and mental health. Its effects can be observed across the life span. Variance in socioeconomic status such as disparities in the distribution of wealth, income and access to resources mitigate social problems that ultimately affect everyone. All benefit from an increased focus on the foundations of socioeconomic inequalities and efforts to reduce the deep gaps in socioeconomic status observed today in the United States and abroad. While older and retired U.S. residents may enjoy a higher standard of living than their predecessors, older Americans remain among the most economically vulnerable groups. Of major concern is whether older Americans will outlive their financial resources. Psychologists and other social and behavioural science professionals possess the tools necessary to study and identify strategies to alleviate these disparities at both individual and societal levels. SES Impacts the Lives of Older Adults The United States is facing unprecedented increases in the older adult population. Americans age 65 and over comprise nearly 13 percent of the U.S. population, and their proportion is estimated to increase to 20 percent of the population in the next 25 years. As the percentage of older Americans rises, so does concern for their econom.

Define intermediate phenotype and then imagine some intermediate phenotypes (e.g. RNA, metabolite, etc) for Down’s Syndrome. Solution intermediate phenotype : it depicts a living being that shows a mix of the phenotypic characteristics that its parents expressed. . In the event that a red blossom cross-pollinates a white bloom, and the subsequent offspring are pink, the posterity portrayed as a intermediate phenotype . It happen when the traits under investigation are neither dominant or recessive. Down disorder (DS or DNS), otherwise called trisomy 21, is a hereditary issue brought about by the nearness of all or some portion of a third duplicate of chromosome 21. It is commonly connected with physical development delays, trademark facial elements and mellow to direct learned incapacity. Down disorder is brought on by having three duplicates of the qualities on chromosome 21, as opposed to the standard two.The guardians of the influenced individual are ordinarily hereditarily ordinary Those who have one tyke with Down disorder have around a 1% danger of having a moment youngster with the disorder, if both guardians are found to have typical karyotypes. The additional chromosome substance can emerge through a few distinctive ways. The most widely recognized cause (around 92–95% of cases) is an entire additional duplicate of chromosome 21, bringing about trisomy 21. In 1.0 to 2.5% of cases, a portion of the phones in the body are typical and others have trisomy 21, known as mosaic Down syndrome. The other basic systems that can offer ascent to Down disorder include: a Robertsonian translocation, isochromosome, or ring chromosome. These contain extra material from chromosome 21 and happen in around 2.5% of cases. An isochromosome comes about when the two long arms of a chromosome isolate together as opposed to the long and short arm isolating together amid egg or sperm improvement. Trisomy 21 is known by the karyotype 47,XX,+21 for females and 47,XY,+21 for guys) is brought about by a disappointment of the 21st chromosome to isolate amid egg or sperm development.As an outcome, a sperm or egg cell is delivered with an additional duplicate of chromosome 21; this cell therefore has 24 chromosomes. At the point when joined with a typical cell from the other parent, the child has 47 chromosomes, with three duplicates of chromosome 21. Around 88% of instances of trisomy 21 result from nonseparation of the chromosomes in the mother, 8% from nonseparation in the father, and 3% after the egg and sperm have combined. Translocation : The additional chromosome 21 material may likewise happen due to a Robertsonian translocation in 2–4% of cases. In this circumstance, the long arm of chromosome 21 is joined to another chromosome, regularly chromosome 14. In a male influenced with Down disorder, it brings about a karyotype of 46XY,t(14q21q). This might be another transformation or already display in one of the guardians. The parent with such a translocation i.

Can “discovery science” (for example, the discovery of a new species of fossil, or a new species of organism that is alive today) contribute to our understanding of evolution? Give examples. Solution Scientists seek natural causes for natural phenomena. This is the most basic description of what a scientist aims to do every day. Their focus is limited to what they can physically observe and measure directly, sometimes with the help of tools such as a microscope. They do not seek to explain the supernatural as it is outside the bounds of science, but instead what is all around them. There are basic methods of gaining knowledge that are common to all of science. Biology uses discovery science , and hypothesis-based science . While discovery science is mostly about describing nature, hypothesis-based science attempts to explain nature. The pair of inquiries are widely used together in research. Observations that can be measured and verified are the data of discovery science. In the study of life, discovery science is used to describe both the simplest of life, and the most complex. From the building blocks of atoms and molecules all the way up to the ecosystems and biosphere, discovery science describes it all. Discovery science is based on the logic of inductive reasoning . Inductive reasoning uses numerous specific observations to make a general statement. For example: all living things are made of cells. This comes after the numerous discoveries of cells in every specimen observed by biologists over two centuries. another example we can take \"humans\". today we found most of the fossils of human lives who lived thousands of years back and with help of that fossils we can understand growth and evolution human life..

You are given a mixed culture containing a anaerobic thermophile, aerobic thermophile and anaerobic hyperthermophile bacteria. How will you separate these into pure cultures? Solution In natural environments, microorganisms usually exist as mixed populations. A pure culture is one by which all organisms are descendants of the exact same organism. A sterile medium is the one which is free of all life forms. It is often sterilized by heating it to a temperature at which all contaminating microorganisms are destroyed. Eventually, in functioning with microorganisms, we ought to have a way of transferring growing organisms from a pure culture to a sterile medium without introducing any undesirable outside contaminants. This approach of stopping unwanted microorganisms from developing accessibility is termed aseptic technique. Microorganisms whose optimal temperature for development is near 0oC are called psychrophiles. The ones that grow optimally between 20oC and 45eC are called mesophiles. These growing most useful at large conditions, 55oC to ~ 70oC and larger, are called thermophiles. Prokaryotes that live at quite high conditions (up to 113oC ) are hyperthermophiles. An organism that will require air for development is called aerobic. An organism whose development can\'t arise in the presence of air is anaerobic. An organism that may grow under either aerobic or anaerobic conditions is a facultative anaerobe. Microaerophilic organisms involve free air but at a limited concentration. Based on this, the plates are incubated at different temperatures with aerobic and anerobic conditions for enhancing the growth of thermophiles and hyperthermophilc bacteria..

What is a possible evolutionary advantage of having introns/exons in genes? Give an example of where this usage is observed or may have occurred. Solution Presence of large noncoding sequences such as introns interspersed with exons in the genome lowers the rate mutations from appearing. Introns enable alternative splicing, a mechanism which enables a single gene to encode multiple proteins that perform different functions under different conditions. Small genome but large information stored. Regulatory RNAs such as siRNA encoded by introns are known to regulate gene expression. Adds to biological complexity..
