Answer:
The answer that are true are:
1) A: Horses and Mules can be bred but their offspring is typically sterile. This could be an example of hybrid breakdown.
2) C: One species of sea turtle mates during the early spring and a closely related species mates during late spring. This is an example of temporal isolation.
3) D: One species of sea urchins can not fertilize another closely related species because the eggs do not have a receptor for the sperm. This is a good example of gametic isolation.
4) E: Damselflies have sensory receptors that are sensitive to touch (tactile cues). Two related species of damselflies are unable to mate because their touch cues are not compatible. This is a good example of mechanical isolation.
Organic matters are generally carbon compounds. Therefore, the organic molecules contain carbon. The main reason of the presence of carbon in the organic molecules is the catenation property of carbon.
The answer is
"Dopamine".
<span>Some drugs fundamentally influence one neurotransmitter or
class of neurotransmitters. For instance, prescription opioids and heroin
deliver impacts that are like (however more articulated than) those created by
the neurotransmitters endorphin and enkephalin: expanded absence of pain,
reduced readiness, and low breath. Different medications upset more than one
sort of neurotransmitter. Cocaine, for instance, joins to structures that
manage dopamine, prompting increments in dopamine activity and creating
euphoria; it likewise delivers changes in norepinephrine and glutamate
frameworks that cause stimulant impacts.</span>
Cellular Respiration occurs in 4 major stages: Glycolysis, NADH
degeneration, Citric acid (or Kreb's) cycle and Electron Transport
Chain. Glycolysis occurs in the cytosol or cytoplasm of the cell. If
oxygen is present, then the next three stages would occur, otherwise
lactic acid or alcohol fermentation would occur. NADH degenration and
Citric acid cycle occur in the matrix of the mitochondria while Electron
Transport Chain occurs in the intermembranal space of the mitochondria.
Most of cell respiration occurs in the mitochondria though. Hope this
helped!
I must say this is a very complete answer but if i might
add,of every part of a cell involved in cellular respiration,the only
organelle is the mitochondria meaning that is the answer.
The protons in the nucleus
