The number of years of divergence from a common ancestor =300,000 years.
<h3>What are mutations?</h3>
Mutations are changes that occur in the DNA of living organisms.
Mutations can be used as molecular clocks if they occur at a constant rate.
Considering the nucleotide substitutions occur by mistake in a segment of ribosomal RNA at a constant rate of one substitution every 100,000 years.
The ribosomal RNA of the two modern-day species have six differences in their sequences.
Number of years of divergence = 6/2 * 100000 = 300,000 years.
In conclusion, changes that occur in nucleotide sequences are known as mutations.

Answer:
It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including transporting oxygen and nutrients to the lungs and tissues
Explanation:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
Answer:
<h3><em>Mitosis</em><em> </em>must happen in the original cell so that each of the daughter cells has a complete set of chromosomes. </h3>
Bonus - Mitosis is used to produce daughter cells which are identical to the parent cells.

1. Wind, water, wave action
2.It changes shape/ form
3. Weathering is the breaking of rocks into smaller and smaller pieces called sediments; erosion is the movement of these sediments by water, ice, wind, or gravity to a new location.
