Correct answer: True
Subsurface mining is one of the types of mining, which is done when minerals that are mined are present below the surface of the earth. This is done because the minerals cannot be obtained from the surface level. Then, in that case, subsurface mining is done.
It is done by constructing a reinforced tunnel down the surface to the place where the mineral resource is present.
Answer:
Molecule not found in DNA is an amino acid.
Explanation:
DNA is a nucleic acid responsible for containing the genetic information of living beings. The basic structure of DNA consists of:
- <em>A sugar, deoxyribose.
</em>
- <em>Nucleotides, including adenine, guanine, cytosine and thymine.
</em>
- <em>Phosphate groups.
</em>
The information contained in DNA allows the synthesis of proteins necessary for the structure and function of living beings. <u>Amino acids</u><u> are part of proteins, but it is a </u><u>molecule that is not found in DNA</u>.
Answer;
It is slowed down dramatically
Explanation;
-The myelin sheath can be described as an insulating layer that is composed of wrappings of the plasma membrane of glial cells that encloses the axons outside the brain and spinal cord. It is a fatty material that coats, protects, and insulates nerves, enabling them to quickly conduct impulses between the brain and different parts of the body.
-In multiple sclerosis the T cells either partially or completely strip the myelin off the fibers, leaving the nerves unprotected and uninsulated. These nerves are not as able to pass messages from the brain to the other body parts. The messages the nerves try to send are delayed or distorted and the messages the brain receives may be misinterpreted.
Answer:
The 'cell membrane' also known as the plasma membrane or cytoplasmic membrane is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells
