Answer:
23
Explanation:
After mitosis two identical cells are created with the same original number of chromosomes; 46. Haploid cells that are generated through meiosis, such as egg and sperm, only have 23 chromosomes, because, remember, meiosis is a "reduction division."
The second statement is correct. Once the enzyme binds to the specific substrate molecule, structural changes can occur in the enzyme's active site to accommodate the product which is the substrate in a transitional state until the reaction is complete to yield the final product.
When the substrate interacts with the enzyme, it undergoes a chemical reaction that allows the atoms to move relative to each other, and the bonds possibly lengthen or shorten which causes the most reactive groups to move closer to each other causing a shape change.
This shape change in the enzyme makes the substrate more amenable to alteration, as it holds the substrate in a transitional state, which helps speed up the reaction that the enzyme catalyzes.
Answer:
A food web is a detailed description of the species within a community and their relationships with each other; it shows how energy is transferred up food chains that are interlinked with other food chains.
Chemosynthesis is the biological conversion of one or more carbon- containing molecules.
