Answer:
A, Both cells will replicate their DNA.
Explanation:
During the cell division, cell passes through several phases and divides. Before each phase, the cell has to pass through the checkpoints. At these cell checkpoints, the cell receives the internal and external signals.
When the cell is arrested at G₀ phase, the cell does not divide until it receives a signal to proliferate but when the cell passes the G₁ phase, the cell will divide continuously.
In the given question, if the cells when in their G₀ and G₁ phase receive proliferation signal, the G₀ phase cell will also divide and will replicate it DNA during S phase as G₁ phase cell will do.
Thus, Both the cells will divide their genetic material.
Answer:
Definition. The first metaphase of meisosis I encompasses the alignment of paired chromosomes along the center (metaphase plate) of a cell, ensuring that two complete copies of chromosomes are present in the resulting two daughter cells of meiosis I. Metaphase I follows prophase I and precedes anaphase I.

<u>Complete Question:</u>
In anatomical, directional terminology, the esophagus is ------------- to the mouth.
a.Superior
b.Lateral
c.Medial
d.Posterior
<u>Correct Option:</u>
In anatomical, directional terminology, the esophagus is<u> medial</u> to the mouth.
<u>Option: C</u>
<u>Explanation:</u>
- The anatomical directional terminology is necessary to define the relative positions of different physical components.
- Devote these words to recall in order to prevent ambiguity when you research or explain the positions of various parts of the body.
- The terms consist roots, prefixes, and suffixes. The source of a word often relates to an organ, tissue or condition while the root is most often defined by the prefix or suffix.
- The center of the body or its orientation towards the west is understood as medial.
