Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow. Some live in or on other organisms including plants and animals including humans. There are approximately 10 times as many bacterial cells as human cells in the human body.

Answer:
Anther contain saclike structure called microsporangia that have micrspores mother cells that develop in to male gametophyte
Explanation:
Sporangia cosist of microspores mother cells and megaspores mother cells in land plant that develops in to male and female gametophyte respectivelly. Then latter on the male gametophyte gie rise to male gametes and female gmetophyte give rise to female gametes and after fusion of the gametes an other gametophyte is arise which give rise to sporophyte and thr sporophyte give rise to gametophtye which is called alternation of generation.
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.
