Explanation:
The cells store glycogen and neutralize toxins and are present in coelomic fluid of some annelids. They are yellowish in colour due to the presence of yellow granules called chloragosomes.
These cells are derived from the inner coelomic epithelium, and help in excretory functions, as most commonly demonstrated in earthworms.

The best explanation that best predicts what happens to the trait over time is that the incidence of mid-digital hair will not change because it offers no selective advantage or disadvantage. A mutation is a sudden, spontaneous random change that occurs in the genetic make up of an organism. The presence or absence of mid-digital hair is controlled by a single gene with two alleles, and the allele H is dominant.

DNA structure is made of molecules called nucleotide. Watson and crick also work on 3-D structure of DNA. this mark the history in molecular biology to understanding the genes control and genetic information.they also work on cell.they use stick and ball to understand to test their idea.</span>
Answer:
A) They form chemical bonds with other atoms
Explanation:
In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
