a) Which of the following statements describes domestication?
It is the process by which animals are trained to do tricks useful for human needs.
It is the process by which wild species have been turned into species with traits that are useful for human needs.
It is the process by which animals build nests to attract mates and raise young.
It is the process by which plants have evolved to fill in ecological niches over time.
b)To illustrate how common corn is in a typical American diet, the film narrator gives many examples, from corn-on-the-cob to foods that contain cornstarch and corn syrup. The narrator also mentions meat. What is the connection between the meat we eat and corn?
Why are female birds more likely to be drab while males have fancy colors or especially long feathers?
A) Drab colors promote a female's survival.
B) Males are under specific pressure to attract a mate.
C) Females choose their mate.
D) All of these are correct.
In the bighorn sheep population of North America, what would happen if all of the large-bodied, large-horned males were hunted, leaving only small-bodied, small-horned sheep?
a)Males could no longer protect females from predators, so eventually all of the sheep would be eaten by predators.
b)There would be no phenotypic variation in the population of sheep, and natural selection could not lead to males with larger horns in the future.
C)The size of horns would no longer be a heritable traits, and would males would not pass this trait to their offspring.
d)Males would begin to use their horns for other behaviors, such as hunting prey or being better competitors.
