The activity of the cell that is not powered by the energy produced through cellular respiration is passive transport.
The cell is the smallest unit of an organism. A cell is self sufficient. Cells obtain energy for their activities via cellular respiration. This is the breakdown of glucose to produce energy.
Passive transport is the movement of solute across the cell membrane without requiring energy for the process. Therefore, it does not require energy produced during cellular respiration.

Explanation:
Hello,
In this case, since the pH is defined by:
![pH=-log([H^+])](https://tex.z-dn.net/?f=pH%3D-log%28%5BH%5E%2B%5D%29)
If we want to compute the concentration of hydrogen we must write:
![[H^+]=10^{-pH}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-pH%7D)
Thus, for both the backyard soils we compute:
![[H^+]_{pH=7}=10^{-7}=1x10^{-7}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_%7BpH%3D7%7D%3D10%5E%7B-7%7D%3D1x10%5E%7B-7%7DM)
![[H^+]_{pH=4}=10^{-4}=1x10^{-4}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_%7BpH%3D4%7D%3D10%5E%7B-4%7D%3D1x10%5E%7B-4%7DM)
It means that:
![\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}} =\frac{1x10^{-4}M}{1x10^{-7}M}\\ \\\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}}=1000](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH%5E%2B%5D_%7BpH%3D4%7D%7D%7B%5BH%5E%2B%5D_%7BpH%3D7%7D%7D%20%3D%5Cfrac%7B1x10%5E%7B-4%7DM%7D%7B1x10%5E%7B-7%7DM%7D%5C%5C%20%5C%5C%5Cfrac%7B%5BH%5E%2B%5D_%7BpH%3D4%7D%7D%7B%5BH%5E%2B%5D_%7BpH%3D7%7D%7D%3D1000)
It means that the concentration of hydrogen at a pH of 4 is 1000 times greater than the concentration of hydrogen at a pH of 7.

Threats to Native Wildlife. Invasive species cause harm to wildlife in many ways. When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. ... Invasive species can also alter the abundance or diversity of species that are important habitat for native wildlife.
Answer:
The body naturally responds by rejecting the new organ because it is identified as a foreign object. Doctors use tissue typing to measure the compatibility of the antigens in the organ to that of the recipient. Another way doctors make sure the organs are accepted is through immunosuppressants that make the immune system does not attack the organ.
Explanation:
must include:
body rejects transplants because it recognizes them as foreign
lymphocytes attack the new organ
tissue typing measures antigens on tissue donor organ for compatibility
immunosuppressants disrupt the replication process of lymphocytes that produce antibodies and makes the immune system less effective
Answer: Uniformitarianism, states that the geological processes that take place today would have taken place in the past and it will continue in future as well.
Darwin suggested that the the evolution takes place over a period of time. It takes time to change and this change takes time.
Both the laws states the same thing, that the geological processes and the process of evolution takes place over a period of time and does not takes place rapidly.
Sorry about the other person I reported her answer.
