Transport proteins (carrier proteins and channel proteins) allow substances into and out of the cell that cannot pass through the phospholipid bilayer (as they’re either to large, charged or not lipid soluble) by facilitated diffusion.
Specifically channel proteins allow ions into and out of the cell by creating a pore in the membrane in which they can move through with their concentration gradient
Answer:
an individual's production of offspring per breeding event or lifetime.
Explanation:
I searched it up. If this is a multiple choice question and this is an option choose this.
sorry im new to this lol
The same rabbit population being constant because the food supply is greater in the spring and supporting a larger number of animals is a false statement.
<h3>What is Population?</h3>
This is defined as the total number of organisms in a particular place at a given period of time.
Factors such as topography, human influence are other factors except food supply which influences rabbit population which is why False is the correct choice.

In two species of birds, both of which form monogamous pair(one male and one female), In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. we would expect that female of species 2 would have sperm from multiple males in their reproductive tracts.
- This is because the species 2 are having many eggs.
- These eggs were formed due to fertilization with multiple male bird partners.
- As a result we can expect eggs with different genotypes.
Thus from the above points we can conclude that two species of birds, both of which form monogamous pairs, female of species 2 would have sperm from multiple males in their reproductive tracts
