Answer:
A vulture attacks weak prey. They hunt by sight, so they often "watch over" the prey until it is ready, by their standards. ... Sometimes vultures wait for a larger feeder to attack the meat first, so that the meat is perfect for eating.
The answer is B. alcohol crosses the barrier that the placenta creates
The placenta usually consist of several layers of cells that act as a barrier for the diffusion of substance that connect the maternal and fetal circulatory system that very important for the fetus' growth. But sadly, it can't block Chemical really well and alcohol can screw it u
Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides.
<span><span>
G1 phase. Metabolic changes prepare the cell for division. At a certain point - the restriction point - the cell is committed to division and moves into the S phase.</span><span>
S phase. DNA synthesis replicates the genetic material. Each chromosome now consists of two sister chromatids.</span><span>
G2 phase. Metabolic changes assemble the cytoplasmic materials necessary for mitosis and cytokinesis.</span><span>
M phase. A nuclear division (mitosis) followed by a cell division (cytokinesis).</span></span>
The period between mitotic divisions - that is, G1, S and G2 - is known as interphase.
<span>Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.</span>
A karyotype is a picture in which the chromosomes of a cell
have been stained so that the banding patterns of the chromosomes appear. This
way it is possible to view abnormalities in the chromosomes. Disorders such as aneuploidy can be diagnosed by karyotype.
It can also help identify local abnormalities on chromosomes such as abnormalities
in chromosome length, and location of the
centromere.
The rough ER is involved with protein synthesis. It helps to produce proteins and help them fold properly.
