Answer:
number of nitrogen bases
Explanation:
<em>The correct answer would be the number of nitrogen bases.</em>
<u>A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.</u>
Mutation can occur in a variety of ways including:
<em>1. Deletion of nucleotide base sequence in the DNA</em>
<em>2. Addition (insertion) of nucleotide base sequence in the DNA</em>
<em>3. Duplication of nucleotide sequence in the DNA</em>
<u>A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.</u>
Hence, the correct option is number of nitrogen bases.

Well they can begin as cosmic rays colliding with water molecules to create clouds. Hope this helps :)
Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
<h3>What are Biodiversity hotspots?</h3>
Biodiversity hotspots may be defined as the regions of the earth which are rich in biodiversity and possesses the following criteria:
- The area should support greater than 1500 endemic species of flowering plants or 0.5% of total plants.
- It possesses a high degree of threat, exploitation, and biodiversity.
- It must have lost about 70% of the original habitat.
- A high degree of endemism (restricted habitat).
Therefore, Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
