Lac operon (lactose) is degraded to glucose and galactose by three enzymes :beta galactosidase, galactoside permease and thiogalactosidase transacetylase.
He is WRONG
Explanation:
Any atom at the ground state has its orbital levels fill from the bottom (close to the nucleus) – up. The inner orbitals are of lower energy state and fill first because the atoms ‘likes’ to exist in the low energy and more stable state. Only when the atom is in an excited state do some of the electrons in the lower orbital levels shift to higher unfilled orbitals.
C) Eutrophication is the answer
Have a Nice Day! :)
True, organisms take in nitrogen and carry out life processes.
This happens if the object goes somewhere where gravity is stronger, or weaker, such as the Moon. The Moon has less mass than the Earth, so its gravity is less than the Earth's gravity. This means that objects weigh less on the Moon than they do on the Earth. The Moon's gravity is one sixth of the Earth's gravity. Hope this helps!
