Dr. Rivera is a microbiologist at a research hospital. She studies bacteria with genetic changes that affect cell division. Dr. Rivera has discovered one change that stops the cell cycle between metaphase and anaphase. The change does not kill the cells, but it does prevent them from dividing. Why will these cells be unable to divide?

The seperation of chromosomes won't be possible.

Explanation:

The metaphase and anaphase are stages in cell division other stages are interphase, prophase, and telophase.

The metaphase stages has to do with the alignment of chromosomes in what is known as mitosis while the anaphase stage deals with the sister chromatids seperation. After the seperation the sister chromatids move towards the opposite poles.

From what we have in the question, the cells won't be able to divide because the chromosomes that would turn to chromatids which in turn goes into the daughter cells won't be able to undergo the seperation.

answer: i would say b.

explanation:

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
