Answer:
Neutrophils help fight infections because they ingest microorganisms and secrete enzymes that destroy them. A neutrophil is a type of white blood cell, a type of granulocyte and a type of phagocyte.
Explanation:
Neutrophils display adhesion glycoproteins on their surface to bind endothelial and subendothelial structures. They move randomly until they find a damaged site. Unless neutrophils are activated, endothelial cells do not tend to adhere. When inflammation mediators (IL-1, FNT) activate endothelial cells, they express P-selectin and E-selectin on the surface. The expression of glycoproteins and L-selectin cause the initial adhesion of the non-stimulated neutrophil to the activated endothelium, slowing it down by rolling it over the endothelium. Activated endothelial cells, opsonized particles, immune complexes, FEC-G, FEC-GM and chemoattractants produce factors that stimulate neutrophil activation. Expressing β2 integrin (endothelium adhesion molecule) Neutrophils expand and form pseudopods. Neutrophil activation also promotes degranulation, superoxide generation, and arachidonate metabolite production.
Probably B would be the right answer
NaCl: natriumchloride. 1 atom of each, so the 2 is too much and I (capital i here) is another element
So for the second excercise the number behind the symbol is the amount of atoms in the compound. So easily 2 atoms of Li, 1 atom of S and 4 of O
Interphase is the period of the cell cycle where the cell is actually growing, developing, and carrying out cellular processes. Essentially, interphase is when the cell is busy being a cell. It grows, synthesizes proteins, replicates its DNA, and so on and so forth.
<span>Mitosis is only the small portion of the cell cycle when it is dividing into two new cells. The rest of the time (interphase), the cell is performing its various functions.</span>
A gene pool is a collection of all the genes in a population. This can be any population - frogs in a pond, trees in a forest, or people in a town.
