Our volitional centre, the motor cortex, is where we impose specific facial expressions in order to convey the desired message or because the situation requires it.
<h3>What is the purpose of the motor cortex?</h3>
- The motor cortex's main job is to provide signals that control how the body moves. 
- It is anterior to the central sulcus and a portion of the frontal lobe. 
- The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
<h3>What kinds of motions does the motor cortex regulate?</h3>
- The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motor neurons to regulate motor behaviour. 
- For the execution of movements to be precise, coordinated muscle activation patterns are required.

Answer:
Mutations in genetic code occurs when DNA is being duplicated.Any changes in the base pairs leads to mutations by trasition or transversion. Change in amino acid leads to change in sequence and thus, mutation. This si carried on to new generation, if it takes place in germ cells.
 
        
             
        
        
        
<span>After ovulation, an oocyte, or egg cell, remains viable in the female body for up to 24 hours. The generally accepted lifespan in a woman's body is 12 to 24 hours for the egg and up to five days for the sperm cells. Intercourse occurring as many as five days prior to ovulation, therefore, could potentially result in pregnancy.</span>
