D. Would be the correct answer.
Answer:
A.) The sexual phase can produce variations within the species
Explanation:
Sexual reproduction allows for the mixing of genes which creates variation. Since asexual reproduction just involves one cell, the daughter cells will be identical to the parent. Thus, no variation is created.
Answer:
Explanation:
It's simply law of osmosis.
In osmosis solvent particles move from lower solute concentration to higher solute concentration until both the solution acquire the same concentration. So when a plant cell is kept in hypertonic solution (having more solute concentration), the solvent particles move outside the cell causing it to shrink, which is also known as plasmolysis of cell.
When a plant cell is kept in hypotonic solution (having less solute concentration), the solvent particles move inside the cell causing it to swell up which is also known as deplasmolysis. But due to the presence of cell wall, plant cell can not burst. Cell wall is a very stratchable boundary made up of cellulose mainly which makes the plant cell non-collapsable (but animal cells can burst in hypotonic solution due to absence of cell wall)
Have a great day!!!!!!!!
Answer: d. Low genetic variability
Explanation:
Low genetic variability can be a reason this is because of the fact that this will not support the organisms to fight against the disease causing pathogen. These organisms will not be able to adapt or attain any resistance against disease causing viruses. Hence, the entire population of the gray wolf will die due to this viral outbreak.
Exposure to sunlight over many years can cause mutation in skin cells. Some of these mutations can lead to skin cancer. Suppose a child is born to a mother who has skin cancer. How will the mutations in the mother's skin cells affect the child?
Choose one answer.
a. The child will definitely develop skin mutations.
b. The child will have mutations that have spread to underlying muscle tissue.
c. The child will not be affected by the mother's skin cancer.
<span>
d. The child will be born with mutated skin cells.
</span>Answer.(C)., the child has never had sun exposure so could not have skin cancer
