If the concentration of salt in the fluid surrounding cells decreases and the concentration of other solutes remains constant?
svetoff [14.1K]

Answer:

The cell will swell.

Explanation:

The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.  

This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.

Why is it important to follow strict safety procedures when handling a urine sample
xz_007 [3.2K]

Because you could easily contaminate the results of the urine if you don't follow exactly what the strict rules dictate This could be a very dangerous thing because if you contaminate the results, then other doctors would think that the patient has some disease that needs to be taken care of which in reality they do not. The patient could also have to go through things or waste money on things that they don't need to because there was something in the urine that wasn't supposed to be there which was added because they didn't follow the strict rules. Then the doctor who contaminated it could be sued for malpractice which is never a good thing.

Duchene muscular dystrophy, or DMD, is a recessive, x-linked disease. What would you expect to see in the offspring of a woman w
Harman [31]

It is expected to see in the offspring of a woman who has DMD and a man who does not have the disease that all of their sons and none of their daughters will have the disease

Option A.

<h3><u>Explanation:</u></h3>

Duchene muscular dystrophy, also known as DMD is a recessive, x-linked disease. It occurs when there is a mutation in the dystrophin gene. This mutation further affects the muscles of the body leading it to degenerate and ultimately death.

When a woman with DMD and a man without DMD have an offspring, their daughters and the sons will get the mutated gene signature from the mother as she is the carrier. But since the father has normal genes, the daughters will become the carriers and will not be afflicted by it. This is because the normal X chromosome from the father will be passed on to them. The sons on the other hand will have the disease as they will get one of their mother's X chromosome which would be carrying the mutated gene.
