Answer:
100% pink flowers
Explanation:
If neither allele is dominant, it will create incomplete dominance. So the offspring will neither be red nor white, the offspring will be pink.
Answer: His phenotype will be Bb. He will have brown hair because it is a dominant trait.
Explanation: Heterozygous indicates that there are two different genes present in a genotype (Bb instead of BB or bb).
All elements are made of "atoms", and an atom is made up from 3 basic particles: Electrons are particles with a negative charge :)
Answer:
In hypertonic solutions, the cells will shrink and in hypotonic solutions the cells will fill up
Cells with cell walls will be able to control their tonicity better than cells without cell walls.
Explanation:
Cells with cell walls
- In a hypertonic solution (high solute concentration), water will flow out of the cell into the solution until equilibrium is reached. If the solution has a high concentration of solute the cell may undergo<u> plasmolysis where the plasma membrane detaches from the cell wall.</u>
- In a hypotonic solution: Water will flow into the cell because it has a higher solute concentration compared to the solution. This will continue until the cell is <u>turgid</u>. If more water continues to enter the cell, the cell is at risk of bursting, this takes a while because the cell wall will withstand the pressure.
Cells without cell walls
- In a hypertonic solution: Water will diffuse out of the cell, however there is no cell wall so cell is in danger of shrinking and dying.
- In hypotonic solution: Water will diffuse into cell,the cell will become turgid and if water keeps moving in the cell will burst because it has no cell wall to resist the pressure.
