From what I can tell, The answer is either A or B. Mammals have what is called an Endoskeleton, which means that their skeletons are inside their bodies. A way to remember this is Exo- is similar to exit and when you exit something then you are going outside. Endo- sounds like into, which can relate to being on the inside. Insects have Exoskeletons, which are made from Chitin. Now Agonists are also called Prime Mover muscles, which means they are practically the same thing.
The majority of bacteria have a cell envelope component which serves as an outer compartment.
Explain the Plasma membrane components.
The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells.
A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells. A semipermeable lipid bilayer makes up the plasma membrane. The movement of materials into and out of the cell is controlled by the plasma membrane.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it offers a stable environment inside the cell. And that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell.
Hence, the correct answer is the outer membrane.

Answer:
secrete a cytokine that triggers apoptosis
Explanation:
Cytotoxic T cells secrete granzymes and perforins when targeting cells. Additionally they secrete cytokines such as IFN-, TNF-α and TNF-β that act to activate macrophages and help kill infected cells.
Answer:
Explanation:
It is carried out by nitrogen-fixing bacteria. The bacteria live in soil and roots of legumes, such as peas. When plants and other organisms die, decomposers break down their remains. In the process, they release nitrogen in the form of ammonium ions.
All organisms that rely on plants for carbon(either directly or indirectly) will die eventually
Hope this helps :))
