Answer:
The correct statement is - option B.
Explanation:
Unmyelinated axons are the axon that lacks the covering of scwann cells that form the myelin sheath which helps in the transfer or transmit the signals faster and more effectively in neurons. It acts as the insulating layer.
In absence of the myelin sheath, the action potential found everywhere along the length of the axon which leads to slow propagation than in myelinated axons.
Thus, the correct answer is - option B.
The right option is; d. 366 people/mi^2
Population density is a measure of the number of people that constitute the population in a particular area per square kilometer or square mile.
From the question, the population of China is; 1,355,935,022, and the land area is; 3,705,405 mi^2.
Population Density = Number of People / Land Area.
Population Density =1,355,935,022/ 3,705,405 = 365.93 = 366 people/mi^2.
Therefore, the population density of China is 366 people per square mile.
A is the ans for this question
As a result of decreasing Arctic sea ice, animals that rely on the sea level for survival may become extinct as their habitat disappears.
The increase in the atmospheric greenhouse gases means that more radiant energy from the sun that could have escaped back into space is being absorbed, leading to an increase in the global temperature.
The increase in the global temperature means that more Arctic sea ice would be melting and decreasing in size. As the ice melts, the water moves into seas thereby causing a rise in their levels.
A rise in sea level means the disappearance of coastal habitats. Thus, a loss in biodiversity will occur as the habitats of plants and animals disappear as a result of the rise in sea levels.

The answer is endocrine system. It is a collection of glands producing hormones that woulf regulate tissue function, growth development and regulate metabolism. The hormones would then be carried out to the circulatory system.Hope this answer would be of help.
