Hello, our reflexes are governed by the spinal cord since these actions happen quickly thus needing to bypass the brain. The other functions, meanwhile, are controlled by the brain itself, with motor skills and involuntary functions such as respiration being controlled by different parts of the brain.
Hello!! Your best answer would be A - Claudius Ptolemy. Ptolemy believed that the Earth was the center of the universe, whereas Copernicus believed that the sun was the center. Kepler discovered 3 major laws of planetary motion, while Newton discovered gravity. I hope this has helped. Have a great evening.
When cells do not
respond to the signals that normally regulate cell division, cancer results. Cancer cells altered cell division in the
presence of signals that normally inhibit cell growth, with this; they no
longer require special signals to induce cell growth and division. The consequence
of the abnormalities of these cells could lead to mutations in protein-encoding
genes that regulate cell division.
<span>Moreover, they
also inhibit the growth of nearby cells that allow the cancer cells to spread
and invade other tissues. The uncontrollable division form masses of cells
called tumors that can impaired nearby tissues. If these cells stay in their
original site, they are considered benign, if they become invasive, they are
considered malignant which means that cancer cells metastasize, sending tumor
cells to distant locations in the body where new tumors may form.</span>
The condition of the AIDS (Acquired Immunodeficiency
Syndrome) is caused by a virus called HIV (Human Immunodeficiency Virus). The
virus itself attacking the definite type of immune system cell inside the body.
Its cell also known as the helper cells or CD4 helper lymphocyte cells particularly
in the adaptive immune system. HIV ruining these cells, it’ll make so hard for
the body to combat off and guard off other infectious diseases. When people
gets HIV, even slight infection like fever or colds can be much critical
because the body itself has difficulty healing. Hence, immune system of one’s
person will be lowered because the helper cells are slowly being destroyed and it
makes the person unsafe.
Answer:
reacting with nitrogen and oxygen atoms in DNA, these compounds modify certain nucleotides so as to distort the normal pattern of base pairing. If these modified nucleotides were not repaired, they would allow an incorrect nucleotide to be incorporated during replication.
Explanation:
