B, They are both made of protons, neurons, and electrons
Explanation:
Nitrogen and oxygen are both gases at normal warmth and pressure. They are more both elements. They both dissolve at a really cold temperature.
They're the principal components of Earth's atmosphere.
They're both diatomic gases.
They're both nonmetals.
They're both light elements.
Both of them are involved in the CNO cycle.
In flowering plants the process of mitosis is restricted to the apical
and to
In growing mammals
mitosis can occur throughout the body.
However, not all regions of the young mammal grow at the same
rate and this is called
growth.
In the cell cycle, replication of DNA occurs in the..
.............phase,
after which there is a lag or gap phase, called the
phase,
before actual mitosis starts. The chromosomes also replicate before the
onset of mitosis, but this replication is not visible until the middle of the
. stage.
At this stage, each chromosome consists of two

Answer:
This question is incomplete
Explanation:
This question is incomplete but there are some general facts that can be made.
Firstly, mitosis only occurs in meristematic tissue of plants which includes apical and lateral meristems
There are 4 phases in a cell cycle
1) G1 (gap 1) phase: This is the first phase of the cell cycle that has to do with an increase in the size of the cell. Major cellular components duplicate in size here.
2) S-phase: DNA replication occurs here.
3) G2 (gap 2) phase: This is the gap phase that comes after the S-phase. The cell undergoes further growth here and the organelles of the cells are also prepared for cell division.
4) Mitotic phase: There are four stages here
i) prophase: Chromosome condenses and becomes visible at this stage. And there is the emergence of spindle fibre from centrosomes.
ii) metaphase: Spindle fibre develops and sister chromatids are attached to
separate spindle.
iii) anaphase: Cohesin, which holds two sister chromatids (of chromosomes) together, breaks down and are pulled towards opposite poles.
iv) telophase: Chromosomes begins to decondense at opposite poles and actual cell division starts as mitotic spindle breaks down.

Hydrochloric acid is secreted by B. parietal cells.
Parietal cells are involved in gastric acid secretion and help digest food, absorb minerals, and fight harmful bacteria.
Parietal cells (also known as oxygen cells) are gastric epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factors. These cells are found in the gastric glands in the lining of the fundus and in areas of the body of the stomach.
There are several cell types in the stomach, each with a specific mechanism of action. Chief cells produce pepsinogen, which is converted to pepsin by hydrochloric acid in the stomach. Parietal cells produce hydrochloric acid, which enables this conversion.
