Suppose that a meteorite crashes into earth and a sample of it is taken to a local research lab for analysis. embedded several inches within the rocky structure, a microscopic cluster of dormant, spore-like structures is found. the scientists culture some of this material in a standard microbiological nutrient broth, and they are surprised to find many single-celled "organisms" moving around, growing, and reproducing in the broth. the "organisms" behave the same in both daylight and dark conditions, do not require oxygen, and thrive under a wide range of temperatures and ph levels. they stop moving, growing, and reproducing, however, when fewer nutrients are available in the medium. in this scenario, the "organisms" most closely resemble a(n)

Two male mice, which we will call male a and male b, are both phenotypically normal. male a was from a litter that contained half phenotypically normal mice and half dwarf mice. the mother of male a was known to be homozygous for the normal igf2 allele. male b was from a litter of eight mice that were all phenotypically normal. the parents of male b were a phenotypically normal male and a dwarf female. male a and male b were put into a cage with two female mice that we will call female a and female b. female a is a dwarf and female b is phenotypically normal. the parents of these two females were unknown, although it was known that they were from the same litter. the mice were allowed to mate with each other, and the following data were obtained: female a gave birth to three dwarf babies and four normal babies. female b gave birth to four normal babies and two dwarf babies. which male(s)mated with female a and female b? male a with both females male a with female b, and male b with female a male a with female a, and male b with female b could not be determined male b with both females
