If an animal cell is placed in plain water, It will swell and burst. The bursting of the cell is a result of which biological pr

densk [106]

Answer:

Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.

Explanation

Cells encounter osmosis due to their semi-permeable membranes. Water can flow past cell membranes. A given cell placed into distilled water will have some water flow into it, causing it to burst. A given cell placed in a very concentrated water will have some water flow out of it, causing it to shrivel. A given cell placed in a solution with the same concentration of minerals as the cell will have an equilibrium of water flowing in and out. This is the case of IV (Intravenous therapy) when we want to deliver substances into a human blood. We want to make sure the liquid delivered is as concentrated as the blood to avoid cell shriveling or bursting.

This picture above sums up the 3 cases cells could face in a solution.

Good luck!

a geneticist notes that crossing a round radish with a long radish produces oval radish. when oval radishes were crossed with ov

stepladder [879]

If the shape of radish is under the control of one gene, for example A than we can say:

AA is dominant homozygous genotype-round radish phenotype,

aa is recessive homozygous genotype-long radish phenotype

If we cross round and long radish:

P: AA x aa

F1: Aa Aa Aa Aa

Aa is heterozygous genotype-oval phenotype

If we than cross the F1:

Aa x Aa

F2: AA Aa Aa aa

This means that the ratio between the phenotypes woul be 1:2:1 (round:oval:long).
