Answer:
The main function of the circulatory system is a To transport material throughout the body.
Explanation:
Blood in an important component of circulatory system.Blood contain Red blood cell that in turn contain hemoglobin which helps in the transport of oxygen and carbon dioxide to and from various body tissue.
The circulatory system also helps in the transport of nutrients such as glucose to various parts of our body such as heart,muscle,brain etc.The glucose molecules are utilized by those organs to perform their physiological functions.
The circulatory system also transport various hormone from the region of secretion to the target cell .
Examples of positive and beneficial mutation:
- Antibiotic resistance by bacteria
- Almond tree gene mutation
- Humans immunity to HIV
Examples of negative and harmful mutation
- Cystic fibrosis
- Frame shift mutation
- Cancer
Examples of neutral mutation;
- Bovine and human insulin
- Silent point mutation
- Missense mutation
<h3>What are mutation?</h3>
Mutations are results from change in gene structures that leads to variations in form that can be transferred or passed down to generations. This is usually caused by alterations in the single base unit of DNAs by insertion, deletion or rearrangement of genes or chromosomes.
Positive and beneficial mutations result in retained from of adaptation like antibiotic resistance by bacteria, harmful mutation causes harm such as cancer, while neutral has little or no effect example, silent mutations.

Well the what is the theory explain the cell theory to your self first
Answer:
Option (b).
Explanation:
Melting temperature may be defined as the temperature at which the DNA strand melts. The melting temperature depends on the Guanine and cytosine content of the DNA.
The thymine binds with Adenine with two hydrogen bonds whereas cytosine binds with guanine with three hydrogen bonds. More energy is required to break the guanine cytosine bonds and they have high temperature. The second strand 5'-ACGGCTACG-3' contains more GC content and hence have high melting temperature.
Thus, the correct answer is option (b).
Answer:
The correct answer is - scatter plot.
Explanation:
A Scatter plot is one of the visualization tools which is used to show or represent how much a single variable is affected by the other or what are the effects they have on one another. This visualization tool uses the position of dots on a graph to represent the values of variables.
Scatter plot helps in the show the relation or correlation of variables like temperature and radiation as they affect one other, if the dots are closer it means they have more correlation and vice versa.
Thus, the correct answer is - scatter plot.
