<h3>What is a strenuous exercise?</h3>
A strenuous exercise is one that takes a lot of energy from the person that is engaging in it. Being engaged in a strenuous exercise would mean that the person would sweat so much and loose a lot of fluid in the process.
In the course of strenuous exercise, it is possible for a person to become dehydrated especially on a hot day when the temperature is as high as 81°f and the relative humidity is 80 percent.
This makes it important that these practice sessions must hold at a time when the weather is not extremely hot and so much arrangement must be made to keep the members of the team hydrated throughout the football practice.

Answer:
support increased DNA synthesis
Explanation:
Folic acid (folate) is a complex B vitamin. Along with vitamin B12, folic acid is required for the formation of normal red blood cells and for the synthesis of DNA (deoxyribonucleic acid), the genetic material of cells. Folic acid is also necessary for the normal development of the fetal nervous system.
Pregnant women or women of childbearing age should take folic acid supplements to reduce the risk of having a baby with a birth defect, especially neural tube defects. The folate serves to ensure a healthy pregnancy and good development of the baby. If a pregnant woman has folic acid deficiency, there is an increased risk of having a baby with a congenital spinal cord or brain defect (neural tube defect).
