Answer:
The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".
Explanation:
Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.
Answer:
Regulating
Explanation:
According to Millennium Ecosystem Assessment, there are four major categories of ecosystem services. These services include:
1. Provisioning
2. Regulating
3. Supporting
4. Cultural
The Regulating category is the category that consists of Air and water quality - Purification, climate, erosion, disease transmission, and pest proliferation - Biological control, and pollination.
The ecosystem services are services or functions rendered by the natural environment that ensure the environment is sustainable and healthy for human use.
Answer:
The guiding principle of radiation safety is “ALARA”. ALARA stands for “as low as reasonably achievable”.
Answer:
Rhizobium is a bacterium found in soil that helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development.

Pls vote my answer as brainliest
Answer: The given question is not true and false it has some of its missing. It has missing blanks at the place storage protein ferritin and transport protein called transferrin.
Explanation:
If is difficult the iron inside the body. It is ingested by the food that we eat. The iron is stored in the body in the mucosal cells.
The iron inside the body is made to store in the mucosal cells by the help of iron storage protein called ferritin.
The mucosal cells of the intestine sheds after every 3 or 4 days. In case the stored iron in the body is not utilized it is shed along with the mucosal cells of the body.
Hence, the given statement is True.
