2.d.2: Homeostatic mechanisms reflect both common ancestry and divergence due to adaptation in different environments Q422.d.3: Biological systems are affected by disruptions to their dynamic homeostasis. Q342.e.1: 2.E.1: Timing and coordination of specific events are necessary for the normal development of an organism, and these events are regulated by a variety of mechanisms Q583.a.2: In eukaryotes, heritable information is passed to the next generation via processes that include the cell cycle and mitosis or meiosis plus fertilization.

2.28 I am able to use representations or models to analyze quantitatively and qualitatively the effects of disruptions to dynamic homeostasis in biological systems (SP 1.4)2.31 It can connect concepts in and across domains to show that timing and coordination of specific events are necessary for normal development in an organism and that these events are regulated by multiple mechanisms. (SP 7.2)3.7 I can make predictions about natural phenomena occurring during the cell cycle. (SP 6.4)3.8 I can describe the events that occur in the cell cycle. (SP 1.2)3.9 I am able to construct an explanation, using visual representations or narratives, as to how DNA in chromosomes is transmitted to the next generation via mitosis, or meiosis followed by fertilization. (SP 6.2)3.10 The student is able to represent the connection between meiosis and increased genetic diversity necessary for evolution. (SP 7.1)3.11 The student is able to evaluate evidence provided by data sets to support the claim that heritable information is passed from one generation to another generation through mitosis, or meiosis followed by fertilization.( SP 5.3)

A) gamete production. B) 2N to N cells (chromosome number reduction). C) providing genetic variation in sexually reproducing organisms. D) growth of the overall individual. E) providing greater survivability in a changing environment

2. If the two chromosomes to the right were to pair up in the early stages of cell division which phase below would be a correct choice for when this event occurs?

A) Prophase of mitosis B) Prophase I of meiosis C) Anaphase II of meiosis D) Mitotic metaphase E) Metaphase II of meiosis

3. Assume the above cell has a diploid number of 4 (three sets of chromosomes are not pictured). If the

above chromosomes are in the tetrad or bivalent stage of meiosis, which statement below is correct about the events of anaphase I?

A) Two of the tetrads will go to one cell, two will go to the other. B) Sister chromatids will break apart and each will go in one of 4 cells. C) One member of each homologous pair will go into each of two cells. D) The tetrads will separate but each new cell will still be diploid since each

chromosome has two chromatids. E) All of these are possible, leading to great genetic variation.

4. If a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants?

A. Backtrack through her previous experiments to obtain another plant with the same traitsB. Breed this plant with another plant with much weaker traitsC. Clone the plant asexually to produce an identical oneD. Force the plant to self-pollinate to obtain an identical oneE. Add nitrogen to the soil of the offspring of this plant so the desired traits continue

5. Before the time of Gregor Mendel and genetics, sexual reproduction was thought to produce a blending or equal mixing of the parents' traits. Today we know that

A) offspring will be identical to one another and demonstrate traits exactly halfway between the parents' traits.

B) offspring can vary from receiving over 99% of one parent's genes to receiving over 99% of the other parent's genes.

C) offspring inherit essentially 50% of their genes from each parent, but two sibling offspring may share with each other from zero to 23 chromosomes in common from each parent, and further variation may occur due to crossing-over.

D) offspring inherit copies of the same 23 pair of chromosomes from each of their parents but the rate of crossing-over makes them very dissimilar.

E) there is one chance in 23 of getting identical sets of chromosomes from one parent, times

two because there are two parents; therefore, two siblings out of every 46 are really

identical except for crossing-over.6. Which of the following is true concerning cancer cells?

a. They do not exhibit density-dependent inhibition when growing in culture.b. When they stop dividing they do so at random points in the cell cyclec. They are not subject to cell cycle controlsd. B and C onlye. A, B, and C
