Answer:
C
Explanation:
Membranes will allow and inhibit certain ions/molecules. I don't believe it can distinguish whether the molecules are harmful or beneficial!
Answer:
t= 3886.18 years old
Explanation:
Whenever an animal dies de C14 and N14 begin to disintegrate in such a way that the proportion between C14 and C12 decreases, with a semi-disintegration period of 5.730 years, T. To get to know how long it takes an element to disintegrate, we must use this semi-disintegration period, which is the time it takes until the amount of the element is reduced to its half.
We can find the age of the fossil, t, by using the next formula:
t = - (T x ln (C14))/ ln (2)
t = - (5730 x ln (0.625)/0.693
t= - (-2693.12)/0.693
t= 3886.18
Answer: They lack nucleus and other organelles important for the synthesis of the enzyme.
Explanation:
The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.
The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.
As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
I believe its c............... .
The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes.
