PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume?
ohaa [14]

Answer:

Animal cells tend to do best in an isotonic environment, plant cells tend to do best in

a hypotonic environment. This is demonstrated in the attached PDF.

Explanation:

A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst)  when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.

I hope this helps. If not I am really sorry!

Phosphorus in rivers can lakes sinks to the bottom and over thousands of years becomes ______ again.
pshichka [43]

Your question isn't the most clear, but I think your answer is rocks, or more specifically phosphorous rich rocks because the phosphorous will mix with the sediments on the river's/lake's ground forming phosphorous rich rocks.

That means that It'll become a phosphate mineral and later become phosphorous again when the minerals weather.



Hope it helped,

A eukaryotic gene contains 14 exons. Most of the transcripts from this gene contain all 14 exons, but some contain only 11 exons
WARRIOR [948]

Answer:

D. Alternative splicing is the mechanism that produce complexity in the genes by splicing some of the protein coding part (exons) of a genes

Explanation:

There are certain splicing enhancers sites present in Exons which facilitiates the binding of RNA binding protein specifically SR protein family rich in Serine and Arginine residues. This SR protein will help in splicing of exons.

The significance of this type of mechanism is the ability of a cell to produce an isoform of protein which have retain their function.

This mechanism also help is diversity or in short in evolution.
