Which of the following best describes how a cell’s dna can change through mutations?

dna segments from broken-down prokaryotic cells are taken in and incorporated into the dna of living cells.

a virus takes in a segment of dna from one bacterial cell and inserts it into another bacterial cell.

a bridgelike connection forms between two prokaryotic cells, through which genetic information is transferred.

changes in a cell’s dna sequences occur during replication, and those changes are passed on to daughter cells.

Cells tend to have a relatively small and uniform size. why aren’t cells larger?

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
