Answer:

Sister chromatids. (Ans. B)

Explanation:

Sister chromatids are defined as the identical chromatids formed by the DNA replication of the chromosome, both copies of chromatids are joint together by a centromere. A pair of chromatids are known as dyad.

A set of sister chromatids formed during the S phase or synthesis phase of interphase, while all the chromosomes present in a cell is replicated. During the process of mitosis, or second division of meiosis the two sister chromatids are gets separated from each other into two different daughter cells, and each cell receives one copy of the chromosomes.

WARRIOR [948]

Answer:

The correct answer is option B. "12 hours".

Explanation:

The process of mitosis in mouse fibroblast cells have been studied and characterized for researches purposes. Therefore, it is possible to predict that it will take around 12 hours for mouse fibroblast cells to begin the process of sister chromatids separation after finishing growing its organelles and synthesizing proteins. If the process takes less time than 12 hours will indicate a premature sister chromatid separation, and that something has caused down regulation or inhibition the histonedeacetylase (HDAC) activity.

A ______ frequency causes a _____wavelength and ______ energy. Lesson: 4.09 Question 10 options: higher, shorter, high low, shor
shtirl [24]

Answer:

A higher frequency causes a shorter wavelength and higher energy.

A shorter frequency causes a greater wavelength and low energy.

Explanation:

Frequency is the number of waves that move at a period of time. It is measured by counting the number of crest point.

Wavelength is the distance between waves. A wave with higher frequency have crest that a very close and therefore the distance between them or wavelength is short compare to a wave with low frequency that the distance are farther apart and they have long wavelength. Therefore to generate high frequency of wave , more energy is required to do this .
