Explanation:
Carbon has four electrons in its outer most orbit and it can share four more electrons from other atom to complete its valency while oxygen has 6 electrons in its outermost orbit and it can either charge the electron or gain two electrons from other atom.
Therefore in , the carbon atom shares its two electrons with two electrons of each oxygen atom and forms double bond with it. Thus, total pairs of electron to be shared by the atom of the molecule is two.
Answer: Decomposer
Explanation:
Bacteria feed on the dead and decaying organism, in which they feed on them and obtain energy from them.
It is not a mutual relation because the host cell on which they feed is not alive. They eat the organic matter that is present in environment.
The bacteria and fungi clean the environment in this way. The dead plants and animals are decomposed in the environment and the nutrients get back into the soil.
hence, the correct answer is option B
They use two different systems - xylem moves water and mineral ions from the roots to the leaves - phloem moves food substances such as sucroseand amino acids from leaves to the rest of the plant.
