MOST ENZYME ASSISTED REACTIONS ARE REVERSIBLE.
this is because :
1. most enzyme assisted reactions are fast , not slow.
2. most enzyme reactions cannot take place at any temperatures as enzymes get denatured at high temperatures and so are will become unable to work.
3. ribosomes are organelle in cytoplasm which form proteins for cells.....as enzymes are proteins we can say they also manufacture enzymes.......but it is not necessary that enzyme assisted reactions can only take place within a ribosome.
4. but it is known that MOST enzyme assisted reactions ARE reversible.
so option 4 is true.

Answer:
Geographic isolation
Explanation:
Geographic isolation occurs when a population is split by geographic factors, such as the flood mentioned. They can become separate species over time and will no longer be able to produce viable offspring. Hope it helps :)
Answer:
42
Explanation:
Atoms have a neutral charge overall, which means they have an equal numbers of positively-charged protons and negatively-charged electrons. Here, an atom of arsenic with 33 electrons must also have 33 protons.
The mass of any atom is contained in its <em>nucleus</em>, a part made up of protons and neutrons - particles with no charge. Both protons and neutrons are exactly 1 atomic mass unit each, so to find the atomic mass of an atom, we can use the formula
(# of protons) + (# of neutrons) = atomic mass
or equivalently:
atomic mass - (# of protons) = (# of neutrons).
For arsenic, we have an atomic mass of 75 amu and 33 protons, so using our formula:
# of neutron = 75 - 33 = 42 neutrons
