Answer: Option A) sensory somatic nervous system-controls skeletal muscles
Explanation:
The somatic nervous system (SNS) is controlled by the brain, and direct conscious or voluntary actions by stimulating the skeletal muscles.
For instance: On seeing an oncoming vehicle, a cyclist will swerve to a safe path. This is a voluntary action, where the skeletal muscles are stimulated by the somatic nervous system to avoid hitting the oncoming vehicle.
Answer:
Option C, 
Explanation:
The diploid number of chromosomes are represented as 
.
Here the somatic chromosome number is 
which can be represented in the "" format with N being equal to 
.
Now, as we know that the total number of chromosomal combination with chromosome number being
is equal to
Substituting the given values in above equation, we get -
Therefore, total of different combinations of centro-meres could be produced during meiosis.
Hence, option C is correct
