c)make-up of the gene pool

d)migration of the population

Explain what distinguishes one species from another

Tuesday -

Explain

Wednesday –

In humans, the pelvis and femur, or thigh bone, are involved in walking. In whales, the pelvis and femur shown in the figure are ______because

______

Thursday

In a species of plant, the sudden appearance of one plant with a different leaf structure would most likely be the result of ______?

a. / chromosomal mutations / c. / asexual reproduction
b. / slow environmental changes / d. / stable gene frequencies

Explain why each of the wrong answers is wrong and why the right answer is right. Because it is so or that type of explanation will result in zero points. Use complete sentences.

A random change in gene frequency in a small population is called ______
Modern sea star larvae resemble some primitive vertebrate larvae. This similarity may suggest that primitive vertebrates ______

An example of a structure that would be analogous structure to a bird wing would be a
Natural selection acts directly on not
______genetic diversity provides a species with a higher probability of surviving changes to its environment.

9. What cellular process is directly responsible for this regeneration?

a)meiosis

b)mitosis

c)transpiration

d)respiration

10. The ears of foxes help to regulate body heat. The fennec fox lives in thedesert. It has large ears that release body heat. The Arctic fox lives incold Fennec Fox Arctic Fox climates. It has small ears that conserve body heat.

Which of these processes led to the development of different ear sizesin foxes?

a) selective breeding

b) natural selection

c) mutualism

d) spontaneous generation

______/ A. generally, a group of organisms living close to one another that interbreed with one another and do not breed with other similar groups.
______/ B. similar because of convergent evolution, and not because of common ancestry, may have a similar function but a different structure.
______/ C. physical appearance of an organism
______/ D. adaptations some animals use as protection from predators by using colors and markings to look like another animal.
______/ E. all of the genes in a population. Any genes that could wind up in the same individual through sexual reproduction.
______/ F. A process in which some individuals have genetically-based traits that improve survival or reproduction and thus have more offspring surviving to reproductive age than other individuals.
______/ G. a change in a DNA sequence, usually occurring because of errors in replication or repair.
______/ H. inherited from a common ancestor, may have a similar structure but different function.
______/ I.changes in gene frequency in a population from one generation to the next.
______/ J. a process in which humans consciously select for or against particular features in organisms.
