Answer:
Sugars
Explanation:
Phloem is a living tissue inside the plants, where it can flow in either direction. Inside the phloem, it will have a cell, which both ends have walls with perforations. So the sugars will travel through them in both directions.
Surface area is an important factor in limiting cell growth because
a. the cell can burst if the membrane becomes too large.
b. materials cannot enter the cell if the surface is too large.
c. the cell may become too large to take in enough food and to remove enough wastes.
d. waste products cannot leave the cell if the cell is too small.
Answer:
c. the cell may become too large to take in enough food and to remove enough wastes.
Explanation:
The exchange of substances with surroundings is done by cells by the process of diffusion. The rate of diffusion of substances requires the presence of a higher surface area than volume. As the cells become larger, their surface area is reduced with respect to the volume. Therefore, larger cells can not support the diffusion of substances in and out as required for its proper functioning. If cells are allowed to grow continuously, they will not be able to intake the requires materials such as food and to release the waste outside.
The answer should be Genes
A person would have to consider Harriet' s upbringing in that time and imagine all the wrong doing she has seen regarding her parents care; therefore, witnessing her own care as a slave as well. It's no wonder that eventually, one would desire they're own true freedom.
Because of the fact that female mammals have chromosomes from both parents (from the father and from the mother) and all cells have the same inactivated X chromosome female mammals are considered to be mosaic <span>of the maternal and paternal cells.</span>
