Answer:
fewer in number.
Explanation:
A low sperm count also known as oligospermia can be defined as a medical condition which typically involves a man (adult male) having fewer than 15 million sperm per millilitre of semen.
Basically, low sperm count (oligospermia) is usually caused in men due to health and lifestyle factors such as smoking, alcohol or drug abuse, obesity, genetics, sexually transmitted infections (STIs), age etc.
Hence, smokers, alcohol abusers, overweight and obesity men are more likely to have sperm which are fewer in number i.e fewer than 15 million sperm per millilitre of semen.
Generally, a healthy or normal sperm motility ranges from over 20 million to 200 million sperm per millilitre of semen.

Answer:
c. dilated, constricted
Explanation:
During exercise, more energy is required by skeletal muscles. Oxygen is an important component required for energy production hence supply of oxygen is also increased to skeletal muscles. This is done by increasing the blood flow to skeletal muscles since red blood cells carry oxygen. To increase the blood flow, blood vessels in skeletal muscles are dilated so that more blood can reach them.
Blood vessels of digestive system are constricted because during exercise digestion process is not the priority. More blood should reach skeletal muscles than digestive system.
