These organisms convert nitrogen in the soil to ammonia, which can then be taken up by plants. This process also occurs in aquatic ecosystems, where cyanobacteria participate. After nitrogen has been fixed, other bacteria convert it into nitrate, in a process known as nitrification.

It will melt because it is probably hot.
I would probably clean it.

Tin, because it has five energy levels with four electrons in the fifth level
.
Explanation:
Tin has an electronic configuration as
1s2,2s2,2p6,3s2,...........4d10, 5s2,5p2
They have four valence electrons in their outer shell
Among the four diagrams given Tin is least reactive because the atomic radius of tin is largest among all four options. Due to large atomic radius electronegativity decreases and hence Tin is the least reactive element among Neon, Chlorine, gallium and tin.
The electronegativity of an element is its tendency to complete its octet by attracting electrons towards itself. Also tin is at the lowest place in the periodic table among all the four mentioned elements, its ionization energy is also low hence less electronegative and least reactive.
The correct answer is option A, that is, blood.
Cell theory in biology refers to the universally acknowledged scientific theory that living species are constructed of cells, that is, they are the basic fundamental and structural unit of all species, and that all the cells arises from the pre-existing cells. The theory is credited to Schwann and Schleiden. The three postulates of the theory are:
1. All living species comprises of one or more cells.
2. Cell originate from the pre-existing cells.
3. The cells is the fundamental unit of organization and composition in organisms.
Answer:
Explanation:
Never still, the earth and its environment are constantly changing. ... Surviving in a changing world is difficult if an organism cannot change along with it. ... Slowly, the population of fish will become more fully adapted to its new environment. ... Sometimes the changes cannot take place fast enough and a whole population
