If a germ-line cell from a frog contains 10 picograms of DNA during G1 of interphase, then how many picograms of DNA would be pr
DIA [1.3K]

Answer:

10

Explanation:

The cell cycle is composed of three states: interphase, cell division and resting.

The interphase is composed of 3 phases: G1, S and G2 (in this order). During this state the cell prepares itself  for cell division. As part of the preparation the cell duplicates all its genetic material, that is, all its chromosomes. This duplication is done during the phase S.

During the meiotic cell division (composed of meiosis 1 and meiosis 2) a single diploid mother  cell (with duplicated chromosomes) produces four haploid daughter cells. the meiosis 1 produces two haploid cells with duplicated chromosomes, and the meiosis 2 produces 4 haploid cells with normal chromosomes (no duplicated).

If a germ-line cell from a frog contains 10 picograms of DNA during G1, then this cell will have 20 picograms of DNA before the product of the first meiotic division, and will have 10 picograms at the begining of the meiosis 2 (i.e prophase II)

Describe the cell-surface events leading to neutrphil movement to site of infection.
Elina [12.6K]

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.
