The inside of red blood cells is 300 mosm. what will happen to your red blood cells if you become dehydrated and your blood osmolarity increases to 350 mosm?

Answers

Answer 1
Answer:

The right answer is going to move the blood cells and the cells will shrink.

Osmotic plasmolysis is a contraction of the cytoplasm of a cell by vacuolar water exit. This occurs during the exerting of osmotic pressure to the outside, exosmosis when the cell is immersed in a hypertonic solution. Plasmolysis leads, of course, to cell death.

Plasmolysis is thus the process by which cells lose water in a hypertonic solution.
Answer 2
Answer:

The dehydration can cause the loss of water from the blood plasma. As the loss of water occurs, the osmolarity of the plasma is increased. Due to the increase in the osmolarity of the plasma, the blood cell would become hypotonic with respect to plasma.

This would result in loss of water molecules from the blood cells. So, the red blood cell would lose water molecules and will shrink.

The English moth, Biston betularia, is often cited as an example of observed evolution. There are two colors of this moth, light anddark (typica and carbonaria). Kettlewell found that dark moths constituted less than 2% of the population prior to 1848. Then, the
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.
