occurring continuously over a period of time.
An ocular device used to intensify and see micro and macroscopic cells like animal and plant cells is called a microscope.
The rectangular glass piece used in the microscope is called a glass slide.
Therefore, rectangular pieces of glass that are used with a microscope is called glass slides.

In humans, there will be 46 chromosomes in each of the diploid cells after mitosis. Mitosis is the equational division which results in the formation of offsprings with same number of chromosomes as that of parents.
Mitosis is a type of cell division in which the chromosomal number remains constant from parents to the offsprings. It is therefore also known as Equational division.
Mitosis occurs in all the somatic cells of body. In this division, a parent cell divides to form two daughter cells with equal number of chromosomes. In a diploid (2n) cell, there are two sets of chromosomes whereas in a haploid (n) organism there is one set of chromosomes. In humans, the haploid set contains 23 chromosomes whereas diploid set contains 46 chromosomes (23 pairs).

The three main parts of a nucleotide are a phosphate group, a five-carbon sugar (deoxyribose in DNA or ribose in RNA), and a nitrogenous base.
Phosphate Group: This is one of the essential parts of a nucleotide. The phosphate group consists of a phosphorus atom bonded to four oxygen atoms.
It provides a negatively charged backbone in the DNA or RNA molecule, contributing to its overall structure and stability.
Five-Carbon Sugar: The second vital component is a five-carbon sugar molecule. In DNA, this sugar is deoxyribose, while in RNA, it is ribose. The sugar forms the central part of the nucleotide structure and serves as a link between the phosphate group and the nitrogenous base.
Nitrogenous Base: The third crucial part is the nitrogenous base. There are four nitrogenous bases in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, uracil (U) replaces thymine.
The nitrogenous base is responsible for the genetic code and base pairing in DNA (A pairs with T, and C pairs with G).
Therefore, all three components—phosphate group, five-carbon sugar, and nitrogenous base—are integral to the structure and function of nucleotides. None of them can be considered "not one of the main three parts" of a nucleotide.
