Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb. Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers like photosynthetic protists use light energy to manufacture their own food.<span>

The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.(i hope this can help you) :)
Question continuation;
..........type B. Type A is found to be more common in the mainland population from which the island was settled.
How could a geneticist best explain the dominance of blood type B in the island population?
Multiple choices;
A. Random mutations have occurred in the island population.
B. Genetic drift has reduced the frequency of type A individuals.
C. Natural selection has only occurred in the mainland population.
D. Environmental conditions on the island are less favorable for type B individuals.
Answer;
B. Genetic drift has reduced the frequency of type A individuals.
Explanation;
-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.
-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.
