The correct answer is -
C is parent cell
A is under meiosis
B is a sex cell
Explanation:
In the given question, the diagram shows three different cells in which the cell C is the parent cell that is about to undergo meiosis that can be identified by the quantity or numbers of chromosomes present in the cell which is highest among all.
The cell that is already in the meiosis is cell A, it is the cell that is produced after meiosis 1 in the meiosis cell division as it has half number of chromosomes to parent cells.
The sex cell or gamete is cell C that has a haploid number of chromosomes which makes this process reduction division

DNA is made of chromosomes.
DNA manufactures chromosomes.
Answer:
(B) Chromosomes are made of DNA.
Explanation:
i took the test <3
Chromosomes are made of DNA which shows the relationship between a chromosome and DNA. So, the correct option is B.
What are Chromosomes?A chromosome is indeed a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule. Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure. The fact that DNA is a component of chromosomes demonstrates the connection between chromosomes and DNA.
Therefore, the correct option is B.

Can someone explain to me about how the pereodic table is used
Answer:
So basically the rows are called periods, and the columns are called groups. The groups show that those elements have similar characteristics. There are also different families such as the noble gases and alkali earth metals. The elements are placed where they are because of the atomic number which is directly equal to the number of protons there are. The atomic mass is the number of both protons and neutrons. Also, even though the number of protons can be equal to the number of electrons, that isn't always the case. It could be an isotope which is basically for when an element or atom isn't neutral.
