They are both sites of a new cell form
The right answer is B
A primary producer corresponds, in an ecosystem, to an autotrophic living being, that is to say capable of producing organic matter from mineral matter. It is the first element of the food chain. This organism is totally or partially ingested by a primary consumer, itself being the potential target of secondary consumers.
Decomposers are living creatures that contribute to the degradation of dead organic matter or feces by returning them in mineral form. They play a crucial role in an ecosystem because they participate in the recycling of the elements.
Answer:
Cell membrane.
Explanation:
Cytokines may be defined as the small molecules that plays an important role in the cell signalling as well as in the immune system as well. They are made of the peptides.
Pattern recognition receptor are important molecules that plays an important role in the innate immunity. These receptors are present on the surface of the cells like macrophages and monocytes. These receptors are made of the proteins and cannot pass the lipid bilayer. Hence, these receptors are located on the surface of the cell membrane.
Thus, the answer is cell membrane.
The lungs. The left and right ventricle I believe.
