Answer:
Endocytosis is a form of active transport hence require enegry powered by ATP. The amoeba needs to change shape and engulf and envaginate the particle and then use vessicle transportation to get the materials into the cell. This requires that the cytoskeleton - composed of tubules and filaments - contracts and relax accordingly. This requires energy by ATPs just like the myosin and actin of muscle.
Phagocytosis, another form of endocytosis, is used by some cells such as immune cells to engulf foreign material and then destroy them by use of lysozymes. This is how phagocytes protect the body from invaders.
Answer:
Reading graphs: The variable plotted on the x-axis is year while the two variables plotted on y-axis are both wolves and moose.
Interpreting variables: The population of moose rose from 800 to 1550 between 1965-1972 while the population of wolves rose from 24 to 43 between 1973-1976.
inferring: The change in population of moose might cause a change in wolves population as a result of the feeding pattern of wolves, perhaps the contest between them was affected by availability of another prey which allows the predator (wolves) to feed on another prey, hence increasing the population of moose.
Conclusion: The dip in population of moose between 1974 and 1981 could be attributed to voracious feeding pattern the predator (wolves) had on the prey (moose) which inturns allows the dip in population during the above mentioned years.
Predicting: If there is a disease infection in wolves, then there would be an increase in the population of moose the next year as a result of disruption in the predator-prey contest, hence; allows one to be more populated the following year.
Explanation:
From the above assertions, it could be deduced that only when the feeding pattern of the predator (wolves) changes then the population of the prey would either be reduced or increased.

Punnet squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Reginald Crundall Punnett, a mathematician, came up with these in 1905, long after Mendel's experiments. Let's take a look at how Punnet squares work using the yellow and green peas example from im not sure about the tree by three thing but maybe this will help :)
Answer:
According to the model, the "villi" of small intestines is being damaged as an impact of celiac disease. Small intestines are responsible for absorption of nutrients and minerals from food, this occurs through villi, in case of damaged villi absorption is interfered, thus disturbing the digestive system. If the nutrients, minerals or vitamins are not being absorbed well by small intestines then they will be excreted out of the body and will not be transported to the blood and other areas, this would result in deficiency of minerals and vitamins in blood that cause weakness.
