Answer:
macroevolution
Explanation:
Macroevolution occurs due to the genetic differences accumulates in the population of the same species which gets reproductively isolated from the older population and got different environments and resources to live.
Macroevolution leads to the creation of a new species over a long period of time because of the genetic difference that occurs due to mutation in the gene in the population who got reproductively isolated. So the new species evolved from the macroevolution.

Answer:
cellular respiration
Explanation:
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Answer:
B = hydrogen bonding
Explanation:
The water molecule consist of two hydrogen atom one oxygen atom. There is large electronegativity difference between oxygen and hydrogen. Both atoms are bonded through covalent bonds.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial negative. The partial positive end of one water molecule attracted towards the partial negative end of other moleucle. The attraction between them is called hydrogen bonding. In this way large mole are connected with each other. Hydrogen bonding is actually a weak bonding.
