Answer:

See below for answer

Explanation:

<u>A. 200 mOsM NaCl</u>

This solution is hypotonic to the red blood cell (RBC) with penetrating solute. The RBCs will swell up and burst because the water will move into the cells.

<u>B. 400 mOsM urea</u>

This solution is hypertonic to the RBCs with non-penetrating solutes. Water will leave the cells via osmosis and the cells will shrink and appear shriveled.

<u>C. 100 mOsM urea plus 200 mOsM NaCl</u>

This time both penetrating and non-penetrating solute is present. The solution is isotonic to the RBCs and although there will be movement of water between the cells and the solution, there will be no overall change in the concentration of water for each and no change in appearance of the cells.

<u>D. 300 mOsM urea</u>

The RBCs will not lyse nor shrivel as again the solution is isotonic to the RBCs.

The most distinctive characteristic of leaf mesophyll cells is that they are filled with
Katyanochek1 [597]
<h2>Mesophyll cells</h2>

Explanation:

The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts

Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis

Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side

The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves

The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases

If cobalt moved down a period what would it be?
yKpoI14uk [10]
Recall that a period is horizontal, and a group is vertical. 

So if cobalt is moving "down" a period, it would be most logical to say that it would be Ni, or nickel. It could also be Copper, Zinc, Gallium, and so on. Make sense?

What are possible consequences of complete dominance
algol [13]

Explanation:

In complete dominance, the effect of one allele in a heterozygous genotype completely masks the effect of the other. The allele that masks the other is said to be dominant to the latter, and the allele that is masked is said to be recessive to the former.
