Groundwater adds water to lakes, rivers, and oceans.
Answer:
(2) The lowest energy orbits are those closest to the nucleus.
Explanation:
In the Bohr theory the electrons describe circular orbits around the nucleus of the atom without radiating energy, therefore to maintain the circular orbit, the force that the electron experiences, that is, the coulombian force due to the presence of the nucleus, must be equal to the centripetal force.
The electron only emits or absorbs energy in the jumps from one allowed orbit to another, with only one jump occurring at a time, from layer K (n = 1) to layer L (n = 2), without going through intermediate orbits. In said change it emits or absorbs a photon whose energy is the difference in energy between both levels.
In Bohr's model, it is stipulated that the energy of the electron is greater the greater the radius r, so the lowest energy orbits are those closest to the nucleus.

Explanation:
Cahn, Ingold, and Prelog formulated a rule to specify the arrangement of the atoms or groups that are present in an asymmetric molecule. This rule is called a Cahn-Ingold-Prelog system. This system is generally used in the R, S system of nomenclature.
According to this rule, such an atom that is directly linked to the asymmetric carbon atom is given the highest priority that has the highest atomic number. So here Nitrogen atom of molecule is given the highest priority because Nitrogen has 7 atomic numbers. Carbon atom of molecule has 6 atomic number. So it is given 2nd position. Deuterium and Hydrogen have 2 and 1 atomic numbers respectively so the are given 3rd and 4th order respectively.
Answer:
DNA
Explanation:
The eukaryotic cell participates in the formation of complex organisms and contains a nucleus, cytoplasmic organelles, and a cytoskeleton.
- In a eukaryotic cell, DNA is contained in a compartment called the nucleus, which is enclosed by a membrane.
The answer should be DNA based on the wording of the question. Hopefully this helped a little bit.
