Stages of mitosis and what happens in each stage.
Zina [86]
There are 4 stages in Mitosis...
Prophase:
It is the first phase in which the chromatin coil to become chromatids, and those chromatids pair up and the nuclear membrane surrounding them dissolves. The centrioles move to each end (pole) of the cell.
Metaphase:
Where the paired chromatids align in the centre of the cell and spindle fibres attach to them at the centromere. 
Anaphase:
The centrioles act as anchors, tearing the paired chromatids away from each other using the spindle fibres. Each paired chromatid moves to either (the opposite) end of the cell.
Telophase:
Where the chromatids elongate to form chromatin, and a nuclear membrane begins to form around the chromatin at each end of the cell. Cytokinesis occurs in this stage as the cell separates into two daughter cells. In animal cells, there is cleavage as the two cells are starting to separate. In plant cells, a plate begins to form.

The partial pressure of oxygen at a particular point in the bloodstream is 100 mm Hg. Under what circumstance will there be a ne
jekas [21]

Answer:

c. There will be a net diffusion of oxygen from the water into the bloodstream only if the partial pressure of oxygen in the water is greater than 100 mm Hg

Explanation:

Diffusion involves the movement of molecules from the region of higher concentration to the region of lower concentration. If the molecules are gas molecules, they will diffuse from the region of higher pressure to the region of lower pressure.

Hence, for net diffusion to occur from the water to the bloodstream, the partial pressure of oxygen in water must be higher than the partial pressure of oxygen in the bloodstream.

<em>Since the partial pressure of oxygen in the bloodstream is 100 mm Hg, then the partial pressure of the gas in water must be more than 100 mm Hg in order for net diffusion to occur from water to the bloodstream.</em>
