Biotic and abiotic limitations determine the carrying capacity of a population.
<h3>What is carrying capacity?</h3>
Carrying capacity is defined as the maximum number of individuals that an environment can sustain without destroying the environment. It is determined by various factors such as food availability, water, and space.
So we can conclude that Biotic and abiotic limitations determine the carrying capacity of a population.

Explanation:
Answer:
Exterior of the cell.
Explanation:
The pulse chase experiment was done to understand the secretion pathway of the protein at different time intervals. The protein travels through the endomembrane system for its secretion.
The cells of the pancreas are labelled with the leucine which is radioactive in nature. The black spots will be shown on the cell exterior as three hours are enough for the secretion of the protein outside the cell. This indicates that the protein has been secreted out of the cell.
Thus, the answer is exterior of the cell.
Answer:
A concentration gradient will be developed.
Explanation:
1. When the oxygen concentration is more outside a cell, then by the process of diffusion the oxygen will pass into the cell.
2. Diffusion can be described as a process in which molecules move from a higher concentration to a lower concentration i.e. along a concentration gradient. Hence, this process does not require energy.
3. When the oxygen concentration will be more in a cell then again through diffusion the oxygen will move out of the cell.
