Explanation:
In central nervous system bundle if axons are called tracts or fasciculi. They are mostly named on the basis of their origin. Endoneurium layer which is very delicate surrounds axon. Impulses are carried toward the s brain through spinal cord ascending tracts while descending tracts carry impulses from higher regions of spinal cord or brain to the lower regions.
Answer:
Plants have a cell wall
Explanation:
GMO modification is different for plants and animals <u>because plant cells have cell walls, unlike animal cells. </u>
<em>GMO refers to genetically modified organisms - a technique that involves the introduction of foreign genes into the genome of organisms.</em>
GMO modification requires that the genome of a cell is accessed by a foreign gene and in order to do this, the membrane of the cell has to be disrupted to gain entrance by the gene. Animal cells do not have cell walls, and thus, can be accessed directly relevant mechanisms. Plant cells, however, have cell walls and as such, no direct access to the cell membrane can be achieved without having to remove the cell wall first.
Thus, the cell wall is a major factor that makes GMO modification to be different for plants and animals.
From what I remember it's called a substrate
Answer:
option B) is correct
Explanation:
The all or none response means that if a muscle contracts, it will contract completely. Thus implying the all or none law which states:
The potential of a response of a muscle fiber or nerve cell is independent of the potential of the stimulus. If a stimulus is more than a certain critical value it will trigger muscle fiber or a nerve. Most importantly resulting in either an all-or-none response thus reducing possibility of any information loss.
