The answer to that would be archaebacteria since they are prokaryotes (no nucleus) but so is Eubacteria, however archaebacteria can live in very harsh conditions.
Correct answer: A). Light slows down as it moves from the air in to the water, resulting in refraction, or a bending of light.
This is because as light travels through one media it travels in a straight line, however, when it travels from one media to another media it bends, light path bends because of the phenomenon of refraction of light.
The refraction takes place only at the boundary, as the light continues to cross the boundary, it travels in a straight line.
So, as the portion of the pencil is submerged in water, the light will travel from water to air.
Hence it appears to be broken because of refraction of light. So, the correct answer would be option A.
Answer:
Small intestine, liver, bile and lipase.
Explanation:
Digestion of fat occurs in the small intestine. Its digestion occurs with the help of bile, that is made in the liver. Bile breaks the fat into small drops that are easier for the lipase enzymes to change it. Lipase enzymes is a type of enzymes that works only on lipids and lipids are broken down into fatty acids and glycerol. These substances are absorbed by our body and used it for producing ATP for the body.
The appropriate answer for this one is C. Cancer cells divide uncontrollably and therefore the cell cycle would be continuously divide. To add, there is a term known as terminally differentiated cells. These cells that never enter the cell cycle again, meaning they stay in G0 and never divide. However, some cells can be triggered to depart G0 and re-enter G1, which permits them to divide again.
