Answer:
D. It keeps the temperature lower for sperm development
Explanation:
<u>Semineferous epithelium ,of the seminiferous tubules, of the testis is the site of sperm production (Spermatogenesis) , and highly sensitive to elevated and fluctuating body temperature of man. Elevated temperature affect the survival of spermatids , the spermatozaon, and therefore affects spermatogenesis</u>.
To avoid this the testis is located outside the body in the scrotal sack.This positioning aids shielding away of the elevated body temperature; thereby survival of spermatozoan.
The attachment in the scrotal sack is done by the cremasteric muscles of the scrotum. This muscle positions the testis in the best angle to reduce temperature conduct from the body.
It also help by contracting and relaxing, to adjusts the temperature of the testis depending on the environmental temperature.During cold showers,it constricts pulling it close to the abdomen, and after, relaxes returning it to normal position.

Answer:
Pros: Power stations fuelled by fossil fuels or nuclear fuels are reliable sources of energy. This means they can provide power whenever it is needed. The fuel for nuclear power stations is relatively cheap.
Cons: Fossil fuels took millions of years to form in the Earth's crust, and can will be replaced in a very long time after being used. If we keep using these fuels they will eventually run out. Oil and gas will be the first to run out and then coal. When fossil fuels burn, they release carbon dioxide into the atmosphere. Research shows that a major contributor to the green-house effect and global warming is our overuse and burning of fossil fuels. Coal and gas also release sulphur dioxide gas when they are burned. Sulphur dioxide can cause breathing problems for living creatures and is also a major part of acid rain. The power stations themselves are expensive to build.t is also very expensive to dismantle old nuclear power stations and to store their radioactive waste, which is a dangerous health hazard.
Explanation:
Non-renewable energy, unlike renewable energy, is energy that comes from sources that will run out. They will not be replenished in our lifetimes, or even in multiple lifetimes. The most common non-renewable energy resources are fossil fuels. An example of these are coal, petroleum, and natural gas. Carbon is the main element in fossil fuels.
The answer is rice, wheat, and corn.
Croplands, rangelands and pastures, and fisheries and aquaculture provide an important supply of world's food. Nearly 80% of the world's food comes from croplands. People can eat about 50,000 plant species, but only 14 of them supply the majority of world's food. Of those 14, only three grains, and those are rice, wheat, and corn, are consumed by about two-thirds of the world's human population.
