The three gases that are part of Earth’s cycles in both the atmosphere and biosphere are:
- oxygen
- - nitrogen
- - carbon dioxide
<h3>Explain your answer?</h3>
The oxygen, nitrogen, and carbon dioxide are the three gasses that are constantly moving through the atmosphere and biosphere in their own respective cycles.
The oxygen is used by the animals for breathing, but it is also released as a byproduct by the producers. The nitrogen is used as a food source for the producers, as well as the carbon dioxide which is crucial for the process of photosynthesis.
Thus, Part of them is released through decomposition, part by releasing them in the atmosphere or in the soil.

Answer: Codon
Explanation: A codon is a triplet of nucleotides in an mRNA that codes for specific amino acids. There are 64 possible codons. They are called the genetic codes. Three of these codons (UAA, UAG, UGA) do not code any known amino acid and are thus called termination codons. One of the codons (AUG) signals the beginning of translation and is thus called initiation codon.
A penny is at rest is experiencing inertia because it is not moving.
<h3>What is inertia?</h3>
According to Newton's first law of motion, every object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force. This law is also called law of inertia.
Inertia depends on mass because the more massive an object is, the more reluctant it will be to move.
Thus, a penny is at rest is experiencing inertia because it is not moving.

Answer:
Explanation:
1 Long term exposure to harmful genotoxic chemicals or ionizing radiation can cause changes in the base sequence of DNA.Chemicals might induce DNA mutations, such as polycyclic hydrocarbons (fumes found in oil stations, or smoke from a tobacco cigarette), intercalating agents such as Ethidium Bromide (carcinogen), but also radiations such as UV-radiation (C and T bases are most vulnerable and would bind to identical bases unstead of their
2 Genetic changes that are described as de novo (new) mutations can be either hereditary or somatic. In some cases, the mutation occurs in a person’s egg or sperm cell but is not present in any of the person’s other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite. (It is often impossible to tell exactly when a de novo mutation happened.) As the fertilized egg divides, each resulting cell in the growing embryo will have the mutation. De novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder.
Somatic mutations that happen in a single cell early in embryonic development can lead to a situation called mosaicism. These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not. Depending on the mutation and how many cells are affected, mosaicism may or may not cause health problems.
