An example where space would be a limiting factor would be this: Wolves live in a very good habitat for them - there are plenty of animals to be found and eaten. However, because their current habitat is rather limited, they cannot expand beyond a certain size because otherwise they would interfere with the habitat of each other and also reduce the amount of necessary food in the environment.
Answer:
The total magnification of a cell is calculated by multiplying the magnification of the ocular lens (also known as eyepiece lens) and the objective lens.
Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
They help with metabolism and can act as enzymes or carriers and hormones. Protein has amino acids within it
