Answer:
presynaptic inhibition
Explanation:
Presynaptic inhibition is an inhibitory mechanism capable of modulating neurotransmitter release in the central nervous system (CNS), i.e., by suppressing the release of neurotransmitters from axon terminals. Endocannabinoids are neurotransmitters that bind to receptors in other cells, thereby indirectly affecting the activity of other neurotransmitters. Anandamide is a neurotransmitter derived from arachidonic acid -an omega-6 fatty acid-, whose effects are mediated by cannabinoid receptors in the CNS. This major endocannabinoid (anandamide) is thought to inhibit the release of the inhibitory neurotransmitter γ-aminobutyric acid (GABA).
Answer:
Explanation:
Stomata: as it allows the diffusion of carbon dioxide in the cell and oxygen out the cell.But it is held together by the guard cell.
Root hair cell:as this absorbs water and mineral ions efficently it does this by increasing surface area to absorb efficently and it ahs lots of mitochondria for the active transport of minerals ions from a dilute solution in the soil to a concentrated solution in the root hair
Xylem:This is spiral rings which are formed in a cell
The ATP is the adenosine triphosphate. The ATP molecule has the three phosphate molecules attached with the adenosine. The ADP is the adenosine diphosphate. It has two phosphate groups. The number of phosphate molecules is responsible for the amount of energy in bonds. Hence the ATP molecule has the three phosphate group hence it has more stored energy as compared to the ADP molecule which has two phosphate group.
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
