It removes the most fertile part of soil.
Answer:
Option B, The controls on cell growth and divisions can be turned on and off
Explanation:
There are signal proteins that control and regulate the cell growth and division process. For instance, mitogens help in removing the negative controls which would otherwise have blocked the cell cycle progression. Then there are growth factors that synthesize proteins and hence stimulate cell growth. Also there are some survival factors that suppress the apoptosis. Based on these three factors the cell division and growth can be turned on or off.
Hence, option B is correct
Answer:
The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.
Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
Answer:
If "New Hair" work better than "Rogaine", more men in Group C would grow hair over their head than the amount of men in Group B would.
Explanation:
Since Dr. Rodriguez thinks her drug, the "New Hair" would work better than "rogaine", the result of the experiment should be "more men in Group C would grow hair over their head than the amount of men in Group B would". Therefor the whole hypothesis would be: If "New Hair" work better than "Rogaine", more men in Group C would grow hair over their head than the amount of men in Group B would.
