<span>Motor end plates are associated with muscular contractions.
Motor end plates are the large and complex end formation of a motor neuron that
builds contact with the skeletal muscle fibers. Without motor end plates,
muscular contractions will not be possible. This works highly during emergency
situations where the body takes a fight or flight reaction. <span>
<span>A good
example is when the fingers touch a burning candle; these motor end plates get
quick impulses from the brain and send
signals to the muscles to move it away to prevent further damage to the body. Without
motor end plates we would be in a heap of trouble as this is the mechanism of
the body responsible for motor skills and quick reaction time.</span></span></span>
Answer: Both the mouse and human beings are encoding the proteins having similar functions.
Explanation:
The CFTR gene in the mouse and CFTR gene in the human beings encode proteins that perform similar function,this is so because if the results are same then it means that both mouse and human beings are encoding the protein that have similar function.
Option A is incorrect because both humans and mouse are eukaryotes so they have introns and because of that even if the gene sequences are different they can still encode protein.
Option B is incorrect because amino acid sequences can be similar inorder to have the similar function. If glutamic acid is replaced by aspartic acid, it won't have different function the function will remain same. So, identical amino acid sequences are not required. They can be similar too.
<span>Terrestrial radiation is energry that is emmited from the earth from the parts of solar radiation. Solar radiation is radiation and energy off the sun, however, only some of the radiation reches the eath's surface. I beleive the similarity is that both of the radiations originated from the sun.</span>
White blood cells use "legs" to grab ahold of the blood vessel walls to inch their way forward.
The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.
One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).
Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.
This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.
