The document provides an overview of three lessons on human heredity:
1) Human Chromosomes - It describes karyotypes, patterns of inheritance including dominance and sex-linked traits. Pedigrees are used to study human traits.
2) Human Genetic Disorders - Genetic disorders have a molecular basis when changes in DNA alter proteins and phenotypes. Examples include sickle cell disease, cystic fibrosis, and Huntington's disease. Chromosomal disorders like Down syndrome can occur from nondisjunction.
3) Studying the Human Genome - The final lesson likely discusses the Human Genome Project which sought to sequence the entire human genome to better understand human genetics.
An owl pellet dissection found bones from 2 animals, including 2 humeri, 1 femur, 2 lower jaws, 2 skulls, 3 vertebrae, 2 shoulder blades, 2 ulnas/radii, 2 ribs, 6 pelvic bones, and 2 tibias/fibias. The pellet contents indicate the owl's diet consisted of at least 2 animals, and as a tertiary consumer, the owl preys on rats that eat plants.
The earthworm belongs to the phylum Annelida. It has many segments and searches for food at night in the soil. Earthworms are important for enriching soil by turning over tons of soil and bringing nutrients to the surface. The lab involved dissecting an earthworm to observe its external and internal anatomy, including organs like the brain, hearts, and digestive system. Key differences from humans are that earthworms have multiple hearts and need to keep their skin moist at all times.
Ecology notes discuss key concepts in ecology including:
- The biosphere, which encompasses all life on Earth from 10,000 meters below to above the surface.
- Ecology, which studies interactions between life forms and between life and non-living elements.
- Levels of organization from atoms to biomes.
- Biotic factors like producers, consumers and abiotic factors like the sun and energy.
- Food chains which flow in one direction and complex food webs with interactions between multiple organisms.
We have studied cell biology, genetics, and evolution in this class so far. The remaining topics to cover are physiology and ecology. Physiology will look at how living organisms function, while ecology examines the interactions between organisms and their environments.
The human body has organ systems that work together to maintain homeostasis, keeping the human body stable despite changes in the outside environment. Homeostasis refers to the body's ability to remain relatively stable through the coordinated actions of organ systems. This document discusses physiology unit objectives related to how the human body achieves homeostasis.
This document describes an experiment to test how different beak shapes affect a bird's ability to gather food. Students will act as birds with spoons, forks or sporks to collect beans and peas, and the amounts gathered will be counted. The hypothesis is that the spork bird will collect the most food and the fork bird the least. Students will rotate roles as the bird, nest and counter. They will then analyze the results and factors affecting food collection.
The document outlines five areas of evidence for evolution: biogeography, fossils, anatomy and embryology, genetics and molecular biology, and testing natural selection. For each area, it lists questions about how the evidence in that area relates to evolutionary history, processes, and theory.

The document outlines evidence of evolution from biogeography, fossils, anatomy, embryology, genetics and molecular biology, and studies of natural selection. It discusses how the geographic distribution of species relates to their evolutionary history, the use of fossils to trace descent of modern species, homologous structures and similarities in embryonic development suggesting evolutionary change, molecular biology's ability to trace evolution, and how research on Galapagos finches shows natural selection in action.
Next week there is an exam on Chapter 16. Students should prepare by studying assignments like the Darwin video, chapter 16 worksheet, warm ups, and natural selection lab. They should also look over the chapter at home and study in a group for at least 30 minutes each day. Individuals do not evolve, groups evolve.

This document summarizes evidence that supports the theory of evolution from four perspectives: biogeography, the age of the Earth and fossils, comparative anatomy and embryology, and genetics and molecular biology. Each section provides examples for how scientific observations in these areas help trace evolutionary relationships and document how species have changed over time from common ancestors through natural processes like natural selection. The document also discusses how recent research on Galapagos finches supported Darwin's original hypotheses about natural selection by showing adaptations to seasonal changes.
Charles Darwin was a scientist who introduced the theory of natural selection, proposing that organisms evolve over generations through a process where favorable traits become more common in a population due to increasing an organism's ability to survive and reproduce. He made great contributions to the study of evolution by first introducing the idea of natural selection. However, the document incorrectly states that Darwin proposed humans evolved from monkeys, when he actually proposed humans share a common ancestor with modern apes.
This document provides information about RNA, transcription, translation, and gene regulation. It begins by contrasting the structures of RNA and DNA, explaining the three main types of RNA, and describing the process of transcription. It then discusses the genetic code, how translation works using tRNAs and ribosomes to assemble amino acids into proteins, and the central dogma of molecular biology. The document concludes by covering gene regulation in prokaryotes and eukaryotes, including how operons control gene expression and how transcription factors regulate development.
Human heredity is determined by chromosomes, which are structures in the nucleus that contain genetic information passed down between generations. A karyotype maps out a person's entire set of chromosomes and can be used to identify genetic disorders. Traits are transmitted through dominant and recessive alleles, codominant alleles, sex-linked inheritance, and X chromosome inactivation. Common genetic disorders include sickle cell disease, cystic fibrosis, and Huntington's disease, which result from changes in single genes. Some genetic mutations can provide advantages, like resistance to malaria. The human genome project worked to sequence and identify all human genes to further understand genetic inheritance and open up possibilities for new treatments.
This document provides instructions for a blood typing lab. The objectives are to learn how to determine blood types and identify the proper donor for a patient. The lab uses 4 blood samples, 3 antiserum reagents, micropipettes, blood typing slides, mixing sticks, and a biohazard container. Students will deposit each blood sample onto its own slide, add the antiserum reagents to the corresponding wells, time the reactions for 30 seconds, and record their observations. The document does not include the data, analysis, or conclusion sections of the lab report.

The lab uses four blood samples, three antiserum reagents, micropipettes, blood typing slides, mixing sticks, and a biohazard container. Students will deposit each blood sample onto individual typing slides, add the antiserum reagents to the corresponding wells, time the reactions for 30 seconds, and record their observations. The document does not include the data, analysis, or conclusion sections of the lab report.
This document contains summaries of several sections from a chapter on genetics:
1. It discusses different types of gene mutations including substitutions, insertions, deletions, and chromosomal mutations like deletions, duplications, inversions, and translocations.
2. It notes that most mutations are not harmful and lists mutagens as things that can cause mutations, like chemicals and physical agents.
3. It briefly outlines prokaryotic gene regulation using the example of the lac operon in E. coli, and lists promoters, operators, and transcription factors as aspects of eukaryotic gene regulation.
The objective of this lab is to understand how genes are expressed through the processes of transcription and translation. Students are assigned DNA template cards and use a codon chart to transcribe mRNA and translate proteins. They found that transcription occurs in the nucleus by changing DNA into mRNA, while translation occurs in the ribosome by changing mRNA codons into proteins. The student felt they understood the genetic code through using the codon chart and thought the lab would be best completed in groups of two.

According to Asmat tradition, Fumeripits was the first being to exist on earth and created the first ceremonial men's house called a jeu. Fumeripits grew tired of dancing alone on the beach, so he carved human figures from trees and placed them in the jeu, but they were inanimate. To solve this, Fumeripits created a drum from hollowed out trees and stretched lizard skin over it. When he played the drum, the figures miraculously came to life and began to dance, becoming the first Asmat people.

According to Asmat tradition, Fumeripits was the first being and creator of the first ceremonial men's house called a jeu. Fumeripits grew lonely dancing alone on the beach, so he carved human figures from trees and placed them in the jeu, but remained unhappy as they were inanimate. He then created a drum from hollowed out trees with stretched lizard skin and, as he played it, the figures miraculously came to life and began dancing, thus creating the first people, the Asmat, from trees.
This student enjoys huskies and white tigers as pets, and their favorite foods are lasagna and orange chicken with chow mein. Their favorite movies are "The Outsiders" and "A Walk To Remember".
