You can differentiate them as vertebrates.
Bats are mammals
Doves are birds
The correct answer is: D) excited
A molecule is in an excited state when its energy level is higher than the ground state. That molecule stays in excited state for short time and then returns to a state with lower energy. This return to a lower energy level is described as decay and is the inverse process of excitation.
The transition from ground to excited state of an atom is possible if electrons gain energy that is higher than the difference in energies between the two energy orbits.
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.
Answer:
Mutualism
Explanation:
Mutualism: is a relationship between individuals of different species in which both individuals benefit from each other without causing no harm. Example is the nitrogen-fixing bacteria and plants.
Observation is broken up into three parts. The first is the date. Then you have the activity and last you have a brief description of what is being observed.
