John and his sister Brittany are high school students in a small town. Their mother Jill is 40 years old and has just learned that she is pregnant with a child. Genetic testing has indicated that the child has DownÕs syndrome. Their family doctor has recommended that Jill have an abortion. John and BrittanyÕs mother and father have called the family together to discuss their options.

Which of the following statements describes how the family should make this decision?

a. The doctor has more scientific knowledge. The parents should follow the advice of the doctor and have the abortion.

b. The parents should consider the wishes of the mother, since she will carry the greatest responsibility for the child, and do whatever she wants.

c. The parents should consider many aspects of this decision including, religious beliefs, financial burden, the effect on other family members, the motherÕs health, the doctorÕs recommendation and the life of the unborn child and then make the best decision for everyone.

d. The parents should ignore the advice of the doctor and make a decision based on how they feel.

Explain the difference between mitosis and meiosis with respect to the end chromosome number.

Scoring Guide:

4 pts total

0-2 pts - mitosis explanation - results in 2n chromosomes; is diploid

0-2 pts - meiosis explanation - results in n chromosomes; is haploid, or has half as many

ILO:

Explain why reproduction is necessary for the survival of a species.

Scoring Guide:

5 points possible -- one for each correct response

Ideal Answer:

One organism can survive without reproducing. In order for the entire species of that organism to survive they must reproduce. They must have offspring for them to continue producing the same species.

Objective: 01. Compare sexual and asexual reproduction.
ILO:

Compare how sexual and asexual reproduction are similar and different.

Note to the teacher: The following are the recommended steps for teaching the process of comparing from Dimensions of Learning by Robert J. Marzano and Debra J. Pickering.

1. Select the items you want to compare.

2. Select the characteristics of the items on which you want to base your comparison.

3. Explain how the items are similar and different with respect to the characteristics you selected.

Scoring guide:

Possible chart:

Characteristics	Asexual reproduction	Sexual reproduction
# of parents	1 parent	2 parents
How it happens	No fusion of gametes	Fusion of two haploid cells
End result	Identical to parent	Different than parents

Rubric for scoring the process of comparing:

4 Carries out the steps in the process of comparing completely, accurately, and effectively, and with relative ease and automaticity.

3 Carries out the steps in the process of comparing effectively and without significant error, but not necessarily at an automatic level.

2 Makes a number of errors when carrying out the steps in the process of comparing, but still accomplishes the basic purpose of the comparison.

1 Makes so many errors when carrying out the steps important to the process of comparing that it fails to accomplish its purpose.

ILO:

Two colonies of pioneers have arrived on Mars from separate galaxies far separated from each other. Colony A, the Thallaxians, are humanoid forms that reproduce sexually. They came from a planet that resembles Earth in size and climate. Colony B, the Anthallians, are also humanoid in form, but reproduce asexually by cloning themselves. They came from a planet that resembles Venus in size and climate. In the new environments that they face on Mars, both groups face extreme challenges to survive. Consider that both groups have planned to stay 10 million Mars years.

Write an essay predicting how each colony will fare adapting to the harsh environments faced on Mars. Explain how you think that the offspring of both colonies will appear ten million years from now. Describe some the adaptations that you think will allow survival on Mars. Use good scientific reasoning in your answers.

Scoring Guide:

Organisms with sexual reproduction have an advantage in adapting to new environments due to the variability inherent in that reproduction scheme. The colony with asexual reproduction would not be able to rapidly adapt to any changes in environment.

40% - utilization of scientific reasoning

40% - comparison of sexual/asexual reproduction

If mitosis were the only kind of cell reproduction, how might the world be different?

Ideal Answer:

Mitosis is a form of reproduction that a single cell duplicates its nucleus and divides into 2 similar cells. With that as the only form of reproduction, the world would have less variety among the organisms. Without sexual reproduction, some species could possibly die out as they would have less opportunity to adjust to changes in their environment. The changes by mitosis are mutations by natural processes or chemical influences from the environment. (Weaker species would be dominated by the stronger ones and have little chance for changes.)

Describe the advantages and disadvantages of organisms producing hundreds of offspring such as insects and fish versus organisms producing only 1 or 2 offspring such as mammals and humans.

Scoring Rubric:

3 - Insects and fish are lower on food chain and need to produce more offspring to increase chance of survival, insects and fish rarely care for young as mammals do

2 - Mammals develop in a protective uterus and require nourishment from parent; insects and fish are born ready to survive

1 - Insects and fish lay eggs, mammals give live birth
