Learning Team Reflection: Week Two BIO101 Learning Team Reflection: Week Two Week two focuses on chapters eight‚ nine‚ and ten. Chapter eight reviews mitosis and meiosis and how they affect the cell’s life cycle. Chapter nine reviews how chromosomes are inherited and sex-linked genes. Chapter ten reviews DNA’s and RNA’s structure‚ protein synthesis‚ and the replication process. Each member in Team A will provide a reflection on what we have learned‚ any surprises that developed during reading

Reported by: Alejaga‚ Roxanne Mae B. Aleligay‚ Norimie S. OBJECTIVES: After studying this chapter‚ the students should be able to: 1. Know the interrelationship between heredity and the environment in human growth and development. 2. Appreciate the significance of pre-natal development to post-natal development. 3. Identify the different aspects of development. 4. State and explain the principles of heredity. 5. Understand the different stages of development that an individual will

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

1. Paracrine signaling A) involves secreting cells acting on nearby target cells by discharging a local regulator into the extracellular fluid. B) requires nerve cells to release a neurotransmitter into the synapse. C) occurs only in paracrine yeast cells. D) has been found in plants but not animals. E) involves mating factors attaching to target cells and causing production of new paracrine cells. 2. Which of the following is true of synaptic signaling and hormonal signaling? A)

Biology Exam 2013 - Review UNIT: PATERNS OF INHERITENCE Describe Mendel’s experiments: * Chose a female parent; chooses a male parent; pollen is collected from the stamens and dusted onto the female parent stigma; pollen fertilizes the eggs. The ovary develops into the pod and eggs develop into the peas; when peas are planted they develop into pea plants. Why Pea Plants? * Easily obtained * Grown quickly; several generation of peas can be observed * Traits are easily visible

living organisms. Scientists study genetic pattern in different organisms to determine the different trends in a certain population. In every organism‚ we obtain one allele from each parent. Alleles are types of genes that can be identified on the chromosomes‚ which are in the nucleus of the cell. Alleles are either dominant or recessive. Dominant alleles are the ones that are usually phenotypically expressed‚ while the recessive alleles are usually silenced by the dominant

Biology 1. If an interphase cell is treated with cyanide (a metabolic poison)‚ the cell does not divide by mitosis. However‚ if cyanide is added right after mitosis has started‚ the same cell completes mitosis. Which of the following explains this observation? A. Metabolic activity ceases during mitosis B. Cell division does not require metabolic activity C. Energy required for mitosis is produced and stored in the cell during interphase D. Mitotic cells make factors that make them resistant to
