Cells have different components. They can be divided in eukaryotic and prokaryotic. When it comes to the first type, they have a defined membrane for the nucleus. When it comes to the second ones, they have their nucleus in all the cytosol. <em>The cytosol is the space in the cell made of a semifluid subtance with different organelles suspended</em>.
Just to mention some of the organelles that can be there, we can find mitochondrion
, endoplasmic reticulum
, centriole
, among others.
Oxygen is much smaller than a protein. proteins are too large, A protein cannot diffuse across a cell membrane because as the pore radius of the membrane approaches the protein radius, the mobility of the protein is <span>significantly reduced</span>
Answer:
ecosystem
Explanation:
An ecosystem is the biological community of organisms that interact with each other and they share the same physical environment. Even though it is man-made, the aquarium still represents an ecosystem. The aquarium itself is the physical environment in which all the organisms in it live. Since all the fishes live together, they interact with each other in one way or another, thus creating an interactive biological community, resulting in a micro ecosystem.
