Answer:
D.
Explanation:
Secondary succession occurs in an area that has already been inhabited. If a new island forms from the volcanic eruption, new species may move in and start a new ecosystem there.
Answer:
The greater the number of types in which it can be differentiated, the greater its power will be. When the cell is able to divide and produce all the different cells in the body, it has achieved totipotency and has reached its greatest potential
Explanation:
Power is the ability of cells to differentiate themselves in other cell types. The greater the number of types in which they can differentiate, the greater their power.
Totipotency is the ability of a cell to divide and produce all the different cells in the body. When the cell reaches this, it is at its greatest potentia.
At this level of power they are followed by pluripotency, multipotence, oligopotence and finally unipotence.
This organ is the pancreas. It is a very small endocrine gland measuring 6 inches that is located on the left abdomen near the duodenum of the small intestine and the spleen. The pancreas is a very important organ that secretes digestive enzymes like:
pancreatic amylase - breaks down polysaccarides and glycogen into simple sugars
trypsin- breaks down proteins into amino acids
pancreatic lipase - breaks down triglycerides to fatty acids and monoglycerides
ribonuclease - digests nucleic acids
It also secretes insulin and glucagon to regulate blood sugar levels.
