Protein channels + no energy spent + following concentration gradient = passive transport via facilitated diffusion :)
Answer:
bacteria
Explanation:
Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
Answer:
They are the monomers of the proteins.
Explanation:
When hundreds or thousands of amino acids join together, they create proteins, which are then used for many tasks in organisms, such as doing work in cells, help with DNA replication, etc. So, the monomer will be the amino acids, and the polymer will be the proteins themselves.
Because they want to prove their dominance and be better than the others.
