Smokers, alcohol abusers, overweight and obesity men are more<br> likely to have sperm which are?

luda_lava [24]

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.

Prairie dogs are rodents that live in colonies. Black-tailed prairie dog (Cynomys ludovicianus) colonies typically have around 1

Tresset [83]

Population density is the aspect of population ecology of the black-tailed prairie dog does this statement describe.

Explanation:

Population density is the number of organisms are there in per unit area. It is used to measure geographical area occupied by organisms and its statistics.

In population ecology the structure, dynamics and contribution of population of species is studied. The idea of species distribution is studied in it.

The population density determines the number of species or members of particular population are present is a particular area.

An area of low density population will have more resources and more area per organism and less competition for resources and vice versa for high density population.

Prairie dogs have 12 adults per hectare of area this tells the population density of the rodents.
