Homework

You should spend  about 20-30  minutes 4-5 nights a week on biology. If you have no written homework, you should be reviewing your notes and viewing animations.  To view animations see the Biology homepage.

QUARTER THREE

Homework: Read the section from the book to help
you. You should mostly use your notes
to complete the following objectives. The objectives can be used as a checklist
to see if you are prepared for the test. It is best to try to put your answers
in your own words. Please re-state the
objective (in bold, a different color, or underlined) in your homework.

HW1
Due:Mon 3/5

Objectives:

  1. Define gene and allele. Describe the location of genes in
    cells.
  2. Define genotype and phenotype. Provide an example.
  3. Compare and contrast heterozygous and homozygous.
  4. Compare and contrast dominant and recessive. Provide
    an example including genotypes and phenotypes.
  5. Describe how fertilization results in offspring
    that has one copy of each gene from each parent.
  6. Explain the purpose of a Punnett Square. Provide an example.

CW/HW2: Complete the Simple Genetics Practice Problems DUE: Fri 3/2

HW3 DUE: Thurs 3/8

Objectives:

  1. Define incomplete dominance and provide an example.
  2. Define codominance and provide an example.
  3. Define polygenic inheritance and provide  an example.
  4. Describe Mendel’s Law of Segregation of Alleles.
    Include the stage of meiosis it refers to.
  5. Describe Mendel’s Law of Independent Assortment.
    Include the stage of meiosis it refers to.
  6. Define mutation. Provide an example of a disease caused by
    a mutation.
  7. Explain why mutations are not always a “bad” thing.

CW/HW4: Complete the Punnett Square Activity     DUE: Wed. 3/7

CW/HW4: Complete the Blood Typing Activity        DUE:______________________

Project: Meiosis and Baby Simulation Project           DUE: TBA

8.1
Due: Wed 2/8

  1. Discuss the function of DNA.
  2. Describe the structure of a chromosome.
  3. Draw and label a chromosome containing sister chromatids
    and a centromere.
  4. Explain how the chromosome got two sister chromatids and why this
    is important before cell division occurs.
  5. Compare and contrast the terms diploid and haploid.
  6. Comare and contrast body cells and gametes of humans.
  7. Compare and contrast autosomes and sex chromosomes.
  8. Explain how chromosomes determine the sex of an organism.
  9. Define the term homologous chromosomes.
  10. Define karyotype and discuss what it is used for.

 

8.2 Due:____________________________

1. Define binary fission.

2. List the five steps of the cell
cycle (use Fig 8.5 to help you).

3. Define interphase. List
the three stages of interphase and briefly state what happens during each.
(Note that G0 is NOT part of the cell cycle technically)

4. Define mitosis. List the
four stages of mitosis.

5. Discuss the role of the mitotic
spindle.

6. For each of the four stages of mitosis
discuss the events that take place within the cell.

7. For each of the four stages of mitosis
draw and label a diagram with the following: sister chromatids,
centromere, mitotic spindle, centromeres, nuclear envelope (prophase and
telophase only)

8. Discuss what happens to the
cell during cytokinesis.

9. Compare and contrast a cleavage
furrow and a cell plate.

10. Describe the daughter cells
that result from mitosis.
