Answer:
Answer is Serous membrane.
Explanation:
The serous membrane is known to be or can be described as a thin membrane usually consisting of two layers which are separated by a space filled with serous fluid, which is derived from the serum.
The serous membrane are lying the cavity of some certain internal organs of the body, such as the lung and the heart. The fluid produced by the serous membrane,[ serous fluid], serves as lubricant to reduce friction occurring from muscle movement.
Examples of serous membrane are peritoneum and pericardium.
Answer:
Biosphere
Explanation:
The biosphere is the part of the earth that supports life forms. It includes hydrosphere, atmosphere, and lithosphere. Various ecosystems, aquatic or terrestrial, are present in the biosphere. Biotic and abiotic components of a geographical region that interact with each other together make an ecosystem.
The biotic component of an ecosystem includes all the organisms present in it. Organisms may be unicellular or multicellular. All the organisms are made up of one or more cells. Cells are made up of various biomolecules that interact and enable cells to perform the life processes.
Answer: diffusion
Explanation:
Diffusion is the over all movement of molecules from one region where it is in high concentration to another another region where it is in lower concentration.
This movement continues until the concentration of both regions are equal. Smaller non polar molecules are able to diffuse through the lipid bilayer of the membrane .
Movement through the membrane is dependent on the concentration gradient, that is the difference in concentration between the two areas.
It is also dependent on the size of the molecule
