Answer:

Explanation:
Newton's Second Law of Motion states that acceleration is dependent on 2 things: the net force acting upon the object and the object's mass.
This law is shown is these equations:
acceleration=net force/mass
net force=acceleration*mass

Answer: Option D
Antigen is a given substance that stimulates a specific immune system.
Explanation:
Antigen is a substance that can stimulate an immune response by activating lymphocytes (white blood cells) which acts as body defence against infections. Antigen is divided into two which are,
1. Foreign antigen or heteroantigen which is a foreign substance that stimulates immune response.
2. Autoantigen self antigen is a substance in the body that stimulates immune response.
The analysis of all an animal’s genes reveals more about its classification than behavior because fine-tuning evolution is evidenced by homo-logous sequences.
<h3>What is sequence homo-logy?</h3>
Sequence homo-logy refers to different nucleotide sequences that are similar due to a common origin.
Behavior may be due to the convergence of a feature in distinct lineages, but evolution is largely determined by homo-logy between gene sequences.
In conclusion, fine-tuning evolution is evidenced by homo-logous sequences.
