Polar bears in captivity exhibit obsessive patterns of behavior such as pacing back and forth on the same spot, swinging their heads from side-to-side, and using their paws to repeatedly stroke their head. such behaviors are signs of stress. they behave this way even when zoos design their living areas to include elements of the polar bear's natural environment. this shows that polar bears do not do well in captivity. which of the following statements best expresses the main conclusion of the above argument

a. polar bears in the wild live longer than those in captivity.
b. polar bears walk for miles when in the wild
c. polar bears out in the wild engage in obsessive patterns of behavior

Here's one way to follow the scientific method. place the missing steps in the correct position in the process.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses. cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown. cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan. cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan. select the correct statements regarding the mode of inheritance of the coat color genes. a) both genes are x-linked. b) both genes are autosomal. c) one of the genes modifies the expression of the other gene. d) each gene has an additive effect on the intensity of coat color. e) each gene independently specifies three colors. f) one of the genes is autosomal, and the other is x-linked.
