dexar [7]

The answer is reflex action. Impulse that triggers a reflex action does not pass through the brain so as to shorten the time for response. It passes through a reflex arch and this is why the muscles are contracted even without time to think of what happened. The sensory and motor neurons only arch at the spinal cord.

Explain how the law of conservation of energy is applied to the generation of electricity from fossil fuels.
sweet [91]

Explanation:

The law of conservation in generation of electricity from fossil fuels;

 Fossil fuels are derived from the remains of plants and animals.

These fuels stores and preserves chemical energy which have produced through their activities which originates from the sun as form of solar energy.

The chemical energy is obtained for used as fossil fuels.

As fuels, they combine with oxygen in power generating plant to produce heat energy. The combustion process transforms chemical energy to heat energy.

The heat energy is used to heat boilers of water to produce steam. Heat energy is expressed as thermal kinetic energy which are converted to mechanical energy to drive turbines. The turbine is connected to a generator where electricity is produced.

This totally agrees with the law of conservation of energy.

The law states that "energy is neither created nor destroyed but transformed from one form to another"

Chemical energy - heat energy - mechanical energy - electrical energy

The chief distinction in the intellectual powers of the two sexes is shewn by man’s attaining to a higher eminence, in what he t
Vanyuwa [196]

Answer:

False.

Explanation:

This phrase was described by Darwin in "The Descent of Man." Darwin, in his work, considered the superiority of man over woman as an adaptation. Even if we agree that it has at some tribal time contributed to the sexual division of labor, the struggle for gender equality today is proof that evolutionary explanations are not always sufficient, and that they should consider the cultural aspect more what sociobiology has done.

Men did not achieve superiority because of an evolutionary process, but through a cultural process that oppressed and weakened women for centuries. For this reason, the excerpt shown in the question is false. The main distinction in the intellectual powers of both sexes is shown through the capabilities of each individual, whether male or female.
