Answer:
The correct answer will be true.
Explanation:
Myelin is a protective and insulating layer formed around the neurons of the central and peripheral neurons. The Schwann cells in the PNS and oligodendrocytes in the CNS form the myelin sheath around the neurons.
This myelin protects the axons of the neurons as well insulate the neurons which speed up the transmission of the electrical impulse generated in the neurons. If myelin is damaged, these impulses get slow or get damaged.
Thus, true is the correct answer.
Answer:
It could mean that those two populations could be common ancestors because the spelling differences are the same
Explanation:
Surface mining, which is also known as strip mining, is when soil and rock overlaying mineral deposit is removed. It can cause habitat destruction, air pollution from dust particles, soil erosion and pollution. Subsurface mining is removing deposits from the Earth by drilling underneath layers of rock and dirt. To keep the pathways clear, <span>mining companies have to pump out large amounts of water, which go into surface ecosystems. That disrupts the ecosystem by changing the pH conditions of soil and water sources. Placer mining is mining of stream bed deposits for minerals, a way of obtaining minerals and metal resources. Although, because it is small, causes less damage to the surrounding environment it still can disrupt river ecosystems with pollution and sediments.
I hope this helps!!

<u>Answer:</u>
<em>Reduction of sulfur compounds and the release of hydrogen sulfide is happening here.</em>
<u>Explanation:</u>
Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the <em>work of bacteria to reduce sulfur</em> compounds and convert them to sulfides.
There are different types of bacteria that reduce various sulfur containing compounds. They are <em>sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc.</em> In a swamp there is low oxygen availability and organic matter decays in this condition.
<em>The sulfate reducing bacteria oxidizes the organic matter and releases Hydrogen sulfide.</em>
The correct answer is "16%"
16% of body fat in women is considered as low as normal body fat levels in women normally ranges from 22% to 25%. In cases of low body fat levels (i.e. in athletic women), there will be relative amenorrhea because of the suppression of the follicle-stimulating hormone and the luteinizing hormone leading to a type of amenorrhea called athletic amenorrhea.
