simple answer 1 sentence please
Answer:
No
Explanation:
Organisms cannot willingly change their mutations as these things occur by chance and within the genetic code which the organisms have no direct power over.
Answer:
The reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a having a higher reduction potential.
Explanation:
Electrons from NADH and FADH2 flow spontaneously from one electron carrier of the electron transport chain to the other. This occurs since the proteins of the ETC are present in the order of increasing reduction potential. The reduced cytochrome b has lower reduction potential than cytochrome c1 which in turn has a lower reduction potential than the cytochrome c.
Cytochrome c is a soluble protein and its single heme accepts an electron from cytochrome b of the Complex III. Now, cytochrome c moves to complex IV which has higher reduction potential and donates the electron to cytochrome a which in turn passes the electrons to O2 via cytochrome a3.
b. endocrine
c. autocrine
d. exocrine
b. endocrine
Paracrine cells are the ones that secrete a sign directly to its neighbors, to the extra cell space and not to the blood.
Endocrine cells are the ones that secrete a hormone to the blood system to be distributed to some specific place in the body.
The autocrine system is the release of a hormone from the cell to that same cell.
The exocrine glands are those who release a specific type of hormone or enzyme to some part of the body, through canals.

Cuticle and stomata in plants have a similar function to skin.
The cuticle is well known for its functions as a diffusion barrier limiting water and solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack.
In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.
The cuticle itself comprises three layers: the cuticular layer; cuticle proper; and epicuticular waxes. The cuticular layer is the innermost layer, which overlays the primary wall and consists of cellulose and other polysaccharides along with cutin and wax.
