There are 13 species of finches living on the Galápagos Islands. According to the current scientific hypothesis,
these finches evolved from a species of finch that lived on
the mainland of South America. A few finches must have
become lost and landed on one of the islands. These
finches had to survive in a new environment. Different
pressures caused this new population of finches to evolve
differently from the original population. Eventually, the
populations became so different that they could no longer
produce offspring together.
Which of the following signal words best starts the
sentence that begins with "A few finches must
have"?
A. First
O B. Eventually
O C. Meanwhile
O D. Before

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

Based on the law of dominance, we would expect percent of the offspring from this cross to have large teeth.

How are proteins and nucleic acids related? they both provide energy. they both carry genetic information. the structure of proteins is determined by nucleic acids. the subunits of nucleic acids are also the subunits of proteins.
