I would say A. CcSs ( sorry if it’s wrong)
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
Answer:
A sample size of 300 people.
Explanation:
The answer is "a sample size of 300 people".
Usually, the sample size has a significant impact on the accuracy of any study. If The sample size is larger, the result will be better. It is said here that the sample size was only 300 people. Marcus is necessarily indicating that he has a limited window of insight. It means it's showing the limitation of the study. If the sample size were larger than 300, the result would be more accurate.
For this reason, Marcus wants to repeat his research with larger sample size.
You don't have any answer choices as your question suggests, but one difference would be that endothermic, means energy is being absorbed during the reaction, and exothermic means energy is being released during the reaction. endothermic reactants also tend to be more stable than exothermic. hope this helped. ^-^
