Give one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process.
NeTakaya

Answer:

Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).

Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.

In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.

Which of the following best explains why deforestation increases the risk of floods in an area?a. Tree leaves catch and retain r
Illusion [34]

Answer: D) Tree roots improve soil water retention

There are many reasons which states that deforestation increases the risk of flood. First   , some water stay on the leaves and evaporates in to the atmosphere. Second, tree leaves reduce the impact of raindrops on the soil which causes less soil erosion.

Third, tree roots absorb water from the soil, which make the soil dry and it absorb more water rainwater. The roots of tree hold the soil in place and reduce the movement of sediment which reduce the capacity of river to break its banking. Thus, reducing the chances of flood.

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
Nadya [2.5K]

Answer:

2(8x^2-13x+10)

Explanation:

There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.

Let's let A represent the measurement of one of the those angles in our pentagon.

The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.

But we are also given that this equals 40x^2-65x+50.

So that means 5A=40x^2-65x+50.

If we divide both sides by 5 we can find what one of our angles is in terms of x.  So let's do that A=8x^2-13x+10.

So we want to know the sum of two our angles, we want to know what is A+A or 2A.  2A=2(8x^2-13x+10).  To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.
