What cross will produce the most pink flowered plants ​
Finger [1]

Incomplete dominance  will produce the most pink flowered plants.

<u>Explanation:</u>

Incomplete dominance means when an allele from two homozygous parents combine in the offspring. This offspring contains one allele from one parent and another allele from another parent.

Incomplete dominance doesn’t allow just one allele or trait to dominate rather produces a combination of both . The Red flower has RR allele and the white flower has WW allele.

When two flowers are crossed there is probability of RR, WW or RW allele to be formed. The RW heterozygous allele forms the pink flower. The two alleles are expressed as Red and White.

Many freshwater one celled organisms, like paramecium, have contractile vacuoles. there's structures collect and pump out excess
ch4aika [34]

This is because their cells are usually hypertonic to the freshwater they swim in. Their cells will always have dissolved osmotically-active molecules that are critical for cell function.  Therefore, osmotically, water will move from the freshwater to the inside of the cells. If not regulated, the cells would swell and lyse. Therefore excess water has to be actively pumped out to maintain cell homeostasis.

You made a "cell" using dialysis tubing and a concentrated sugar solution tinted red. You then placed the cell in distilled wate
Mrrafil [7]

Answer:

When the cell has 0% sucrose I expect the cell to stay the same.

Explanation:

First of all, this question should not be confused for the statement "When the "cell" has 0% sucrose, did you expect the cell to have gained water, lost water, or stay the same. In this case, the correct answer would have been; gained water.

But, in this question, we are asked what happens to the cells at 0% sucrose concentration. At 0% (no solute) concentration, there is no net movement of water or solute into or out of the cell, because the cell is isotonic to the external environment (distilled water). Osmosis, a special kind of diffusion, is the movement of water, from areas of lower solute concentration to area of higher solute concentration, or from areas of higher water concentration to areas of lower water concentration through a semi-permeable membrane. If the water moves into the cells (hypertonic cells), then the cell gains water and increases in size, but if the cell loses water (hypotonic cell), then it reduces in size

Answer:

don't quote me on this but I think the answers are milankovitch cycles and then climate change
