I think food pantries is the term for a community food collection program that provides groceries to be prepared and eaten at home. Food banks on the other hand are the facilities that collect and distribute food donations to authorized organizations feeding the hungry. Food recovery is the collecting wholesome surplus food for distribution to low-income people who are hungry.
The relationship of blood flow (Q), resistance (R), and pressure (P) in a vessel can be expressed by which equation?
A. Q = P/R.
B. Q = R/P.
C. Q = PQ.
D. P = Q/ R
Answer:
A. Q = P/R.
Explanation:
Resistance is the force that counteracts the blood flow and slows down the speed of the blood flow. It occurs due to friction between blood and the walls of blood vessels. Resistance is regulated by the size of the blood vessels, length of the blood vessels and viscosity. Blood always flows from the region of the higher blood pressure towards the lower one. Therefore, blood flow is directly proportional to pressure and is indirectly proportional to the resistance.
So, Q= P/R
Answer:
Explanation:
it depends on the total percentage of the population. that way we can pick out the percentage of the heterozygous
Parasitism is an interaction in while the host is harmed
Let's start off with an example. Imagine a population of organisms—let's say, deer—with access to a fixed, constant amount of food. When the population is small, the limited amount of food will be plenty for everyone. But, when the population gets large enough, the limited amount of food may no longer be sufficient, leading to competition among the deer. Because of the competition, some deer may die of starvation or fail to have offspring, decreasing the per capita—per individual—growth rate and causing population size to plateau or shrink.
In this scenario, competition for food is a density-dependent limiting factor. In general, we define density-dependent limiting factors as factors that affect the per capita growth rate of a population differently depending on how dense the population already is. Most density-dependent factors make the per capita growth rate go down as the population increases. This is an example of negative feedback that limits population growth.
