The active site is complementary to its substrate due to its specific 3D structure. The substrate fits in to one specific active site so an enzyme will only bind to one substrate. They are SPECIFIC. Lock and key theory.

It depends on the cell type. If it's a tissue cell, it will divide into 2 daughter cells through the mitosis process. If it's a gamete cell, it will divide through meiosis into 4 daughter cells.
Hope this helps!
Answer:its a covalent bond
Explanation:
Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
