Cells go through a series of events known as the cell cycle as they grow and divide. During the cell cycle, a cell grows, prepares for division, and then divides to form two daughter colls. Each daughter col then moves into a new cell cycle of activity, growth, and division. SC.912. L. 16.14
The cell cycle includes four phases - G1 SG2, and M. What occurs during the Sphase?
A. Prepares the cell for mitosis
B..There is intense growth and activity
C. New DNA is synthesized as the chromosomes are replicated
D. Cells increase in size and synthesize now proteins and organelles

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
