Details about comets are described below.
Explanation:
- A comet is a very small solar system body made mostly of ices mixed with smaller amounts of dust and rock. Most comets are no larger than a few kilometres across. The main body of the comet is called the nucleus, and it can contain water, methane, nitrogen and other ices.
- Sometimes comets are referred to as “dirty snowballs” or “cosmic snowballs”. Comets orbit the Sun in elliptical paths – just like the planets.A comet has four components: a nucleus, a coma, a dust tail and an ion tail.
The nucleus of a comet contains the vast majority of its total mass.
- Comets are icy bodies in space that release gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.
- Comets are made of water, ice, dust, and gasses likes carbon monoxide and methane. After identifying what is in the nucleus, you will know what the coma and tail are made of.
The level of phospholipid organzation to arrange themselves into to parallel layers.
Answer:
Diploid cells abbreviated 2n and haploid cells abbreviated 1n because 'n' represents number of chromosome present in the cell. In haploid cells the number of chromosome is half in number while in diploid cells the number of chromosome is double so that's why haploid is abbreviated as 1n and diploid is abbreviated as 2n.
Diploid cells are present in body cells while haploid cells are found in sex cells.
Answer and Explanation:
The lymph node are the sites for the formation of lymphocytes and monocytes. These are concerned with antibody formation and phagocytosis of foreign materials respectively. In the lymph nodes, bacteria and other harmful materials are removed from lymph.
