Answer:
CO2 enters the stomata during the day when they are open for photosynthesis. In exchange, O2 exits the stomata. While the stomata are open, there is a risk of water loss resulting in wilting and maybe death. The stomata help to conserve water at night while they are closed. Also, their waxy covering “cuticle” helps minimize water loss. On a very hot day, the stomata May close to preserve water but it comes with a cost, because if they close, photosynthesis slows down.
Explanation:
Answer - The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom. hopes this helps :)
Answer: 4
Explanation:
A monomer is a small molecular mass molecule that is attached to other monomers, sometimes hundreds or thousands, by chemical bonds, usually covalent, forming macromolecules called polymers. Polymerization is the process of covalent bonding of the smallest monomers to the polymer. During polymerization, chemical groups are lost from the monomers so that they can bond. Examples are:
- Amino acids are the monomers of proteins.
- Nucleotides are the monomers of nucleic acids.
- Monosaccharides are the monomers of polysaccharides.
- Lipid monomers are the monomers of fatty acids
In this case, if we have the A and B monomers, the combinations can be A attached to A, A attached to B, B attached to B and B attached to A. This gives us a total of 4 different polymers.
