Answer:B.) Substitution
Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA molecule. Substitution leads to a point mutation if only one nucleotide is replaced by another.
A substitution mutation occurs when one or more nucleotides in a DNA sequence is replaced by another nucleotide.
Example of substitution is in sickle cell hemoglobin in which valine replaces glutamate at position six in the two beta chains of hemoglobin. In a normal hemoglobin, the two beta chains of hemoglobin have glutamate at the sixth position but in a sickle cell hemoglobin, valine is found at position six on the two beta chains. This is also an example of a point mutation.
The answers include the following:
- Biology is referred to as the study of the study of living things.
- Anatomy is referred to as the study of the structure and systems of the human body.
<h3>What is Anatomy?</h3>
This is regarded as a branch of science which deals with the study of different parts and structures which are found in the body of organisms and have their unique functions.
It also helps to define the relationship between different parts which work to ensure different types of metabolic activities takes place in the body cells thereby making it the most appropriate choice.

Answer:
The light- independent reaction uses the energy from <u>NADPH and ATP</u> to produce <u>Sugar</u>.
Explanation:
The end product of light- independent reaction is sugar (glucose) which is made from carbon dioxide. The energy for these comes from the end results of light- dependent reactions .
This includes NADPH and ATP. This process is termed as the Calvin Cycle.
Steps of the Calvin Cycle include:
1. The formationof a six carbon sugar , Phosphoglycerate, by combination of a five carbon sugar, Ribulose biphosphate (RuBP) and Carbon dioxide.
2. The formation of two molecules of Triose Phosphate by reducing Phosphoglycerate using hydrogen atoms of the light- dependent reactions. This reaction uses ATP.
3. ATP is also used to convert some of the Triose Phosphate back to RuBP.
4. GLUCOSE is produced using the rest Triose Phosphate.
