What BEST describes the DNA in two daughter bacteria cells? A. halved B. doubled C. identical D. unrelated

Answers

Answer 1

Answer: I think the correct answer from the choices listed above is option C. The DNA in two bacteria cells can be best described as identical. As long as, there are no mutations or horizontal gene transfer. Hope this answers the question. Have a nice day.

Answer 2

Answer:

The correct answer would be C. identical.

Bacteria divides into the two daughter cells through the process called binary fission that is, a type of asexual reproduction.

Thus, it does not involve the formation as well as fusion of gametes.

Before the cell division, the DNA of the bacteria gets doubled through mitotic division so that it can be divided equally into two daughter cells.

Thus, both the daughter cells get identical DNA.

A scientist is trying to determine the relationship between clams, snails, and squid. When she generates a molecular clock, she is surprised to see that clams and squid are more closely related than clams and snails. Which did the molecular clock data show?Clams and squid have been evolving separately for a longer time than clams and snails.

Clams and squid have been evolving separately for a shorter time than clams and snails.

Clams and snails have more in common genetically than clams and squid.

Clams and snails are more similar in related structures than clams and squids.

Answers

I think the last answer presents the truth reveled by the molecular clock. The statement is true, it claimed that clams and snails have stronger relationship than squids. The findings can be strengthened with the origin of their class. All of the said animals came from Phylum Mollusca which make these animals related, but stronger structural relationship can be identified with snails and squids because they are both in the Class Gastropoda. The squid came from Class Cephaloda which makes it more related with octopus and cuttlefishes.

its the last option (Clams and snails are more similar in related structures than clams and squids.)
