Below are the choices that can be found elsewhere:
a.66 s
<span>b.68 s </span>
<span>c.70 s </span>
<span>d.78 s
</span>
<span>An outlier is a result that is abnormally too high or too low. Most of the results fall between 66 and 70, but 78 seems to be abnormal, so it's your outlier. The answer is D. Hope it helps :)</span>
Answer:
Yes...This is an example of speciation by natural selection
Explanation:
As we know that natural selection always promote those evolutionary changes that are necessary. Changes that happen in chromosome number always promote with a specie that is closely related to the parent specie and produce fertile off-springs. These new generations are most adaptable and can survive in the environment more efficiently than the previous ones.
Additionally, other than natural selection, speciation can also happen as a result of random mutations, genetic drift and by means of artificial selection as well. But the natural likelihood of all these is probably low as compared to that of natural selection.
Answer:
Skeletal muscle stores glycogen because it is a heavy consumer of energy.
Explanation:
Skeletal fiber contractions are based on different physiological and biochemical phenomena that happen in every cell and that need an amount of energy to occur. During muscle contraction, <em>myosin binds to the uncovered actin-binding sites, producing littles power strokes that, continuously, lead to muscle contraction</em>. To make this process possible, the muscle needs energy.
Glycogen is a very important energetic reserve polysaccharide for animals. It is stored in the liver and muscles, and when the organism needs energy it degrades glycogen into glucose, which is an available form for the metabolism. In the liver,<em> glycogen</em> is used to maintain constant levels of <em>blood glucose</em>. While in muscles, glycogen plays an important role in the glucose storage as a source of energy, needed and used only for contraction.
During muscle contraction, ATP molecules obtained from glucose are split to ADP and inorganic phosphate.
Some afferent neurons are sec specialized to detect stimuli, whereas efferent neurons send signals to the effectors of the nervous system.
