An enzyme is a biological molecule. They are essential to sustain life.
Answer:
B. phagocytes
Explanation:
Phagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it. The process of phagocytosis often happens when the cell is trying to destroy something, like a virus or an infected cell, and is often used by immune system cells.
break even means that the total income is equal to the total cost.
Therefore, we can equal the total gain to zero.
We have then:
![p (x) = x ^ 3 - 4x^2 + 5x - 20](https://tex.z-dn.net/?f=%20p%20%28x%29%20%3D%20x%20%5E%203%20-%204x%5E2%20%2B%205x%20-%2020%20)
Equaling zero we have:
![x ^ 3 - 4x^2 + 5x - 20 = 0](https://tex.z-dn.net/?f=%20x%20%5E%203%20-%204x%5E2%20%2B%205x%20-%2020%20%3D%200%20)
Rewriting the polynomial we have:
![(x-4) (x ^ 2 + 5) = 0](https://tex.z-dn.net/?f=%20%28x-4%29%20%28x%20%5E%202%20%2B%205%29%20%3D%200%20)
We observe that the polynomial only has a real solution.
Therefore we have:
![x-4 = 0x = 4](https://tex.z-dn.net/?f=%20x-4%20%3D%200x%20%3D%204%20)
Answer:
the year (x) the entrepreneur will break even is:
D. year 4
Answer:
Because of the natural selection
Explanation:
Variation in nature is all we can found out there. Through millions of years nature went with the survival of the fittests, like Darwin said.
When we talk about artificial selection, we talk about humans getting involve on that selection, but we deppend on variation in nature. We can't "create" a new species, but we do can choose the genetic traits we want to prosper and which no.
<span>The answer that is seemingly true, based on the information given, is: Those that preys on blue crabs would opt to a new prey changing the food web. This occurrence was the reason why some of the organisms die because of the decreased number of blue crabs.And eventually, those that are preyed on by the blue crabs would likely to grow their size.</span>
