Julia saw a robin raising 2 blue jay chicks. Julia now thinks that it is possible for a robin to be a biological parent to blue jays. Is Julia's assumption correct? a. No, it is not possible because a robin can only pass robin genes on to its offspring. b. Yes, it is possible for one species of animal to give birth to another species. c. No, it is not possible because robins do not like blue jays. d. Yes, it is possible if the robin's eggs were fertilized with blue jay sperm.
a. No, it is not possible because a robin can only pass robin genes on to its offspring.

SLIDE 97: In a certain breed of cats, having black hair is the result of 2 dominant alleles for hair color (HH). The heterozygous genotype (Hh) produces a cat that has black and white spots. Having 2 recessive (hh) genes results in a white-haired cat. The Punnett square below shows the results of a cross between which 2 cats? a. a black cat and a spotted cat b. 2 spotted cats c. 2 black cats d. a spotted cat and a white cat
a. a black cat and a spotted cat
Which types of organisms are responsible for breaking down decaying waste products? a. producers b. consumers c. decomposers d. autotrophs
c. decomposers
Arial's home is sprayed with a pesticide to control an insect pest. She didn't see any of the insects for a long period of time, but eventually she begins to see insects again. The next time the exterminator sprayed her house, they used the same pesticide, and it had no effect on the insect pest. What is the best way to explain this change in survivorship of the pests' population? a. The original insect population did not pass on their genes to their offspring. b. The insects learned to avoid the pesticide. c. The insects with pesticide-resistant traits survived and reproduced. d. The original insect population was not very diverse.
c. The insects with pesticide-resistant traits survived and reproduced.
Many organisms, including most animals, are able to move around from place to place. The ability to move around ss called locomotion. What advantages does locomotion give to an animal? a.

d. The ability to escape danger and find food and shelter
Both of Tim's parents have brown eyes, but Tim has blue eye. How is this possible? a. The characteristic (blue eyes) is carried in a recessive gene b. Eye color is not a genetic trait. c. This characteristic (blue eyes) must be carried in the dominant gene. d. all of these.
a. The characteristic (blue eyes) is carried in a recessive gene

c. recessive gene
The burdock plant produces spiny seeds that cling to the fur of animals or human clothes. The plant relies on this for reproduction, while the animals are unaffected. This is an example of a. commensalism b. mutualism c. parasitism d. predation
