Answer:
<h2>C.</h2>
Explanation:
This theory tells us that all cells come from existing cells, means all living cells come from the division of pre-existing cells. They do no come spontaneously from non- living matter as early believed. All pre-existing cells divide to form new cells by mitosis or meiosis. New cells never come from non-living matter suddenly, they only come from cell only.
Answer:
-elastic membranes
Explanation:
The elastic membrane or tissue of the arteries allows the artery to bend and fit. It is important for artery to be elastic, because it transports oxygenated blood pumped from the heart to the tissues (except for pulmonary artery which carries deoxygenated blood) and thus have a blood pressure that is higher than in other parts of the circulatory system.
<span>Cellulose is a lot stronger than starch. Starch is practically
useless
as a material, but celluose is strong enough to make fibers from, and
hence rope, clothing, etc. Cellulose doesn't dissolve in water the way
starch will, and doesn't break down as easily.
</span>Your body contains
enzymes that break starch down into glucose to fuel your body. But
we humans don't have enzymes that can break down cellulose.
Answer:
The correct answer is - Pleiotropy.
Explanation:
Pleiotropy is the number of disorders where multiple, and unrelated organ systems are affected in the body of an individual. Phenylketonuria (PKU) is the most cited example of pleiotropy in humans.
It is an inherited disorder that is caused by a deficiency of the enzyme phenylalanine hydroxylase due to mutation in the PAH gene, This enzyme is necessary to convert the essential amino acid phenylalanine to tyrosine. By this disorder, multiple organ systems are affected such as severe skin discolorations and foul odor, and other intellectual disabilities and behavioral problems.
