Answer:

The options are not given but they are gotten from another websites.

A. Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.

B. Capillaries surrounding the brain have pores and are surrounded by membranes of astrocyte cells.

C. Capillaries surrounding the brain have no pores and are not surrounded by membranes of astrocyte cells.

D. Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.

The correct answer is option A.

Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.

Explanation:

Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells because

Capillaries are tiny blood vessels in the circulatory system that connect aterioles to venules. They are the most abundant or they are much blood vessels. They can penetrate the tissues of the body which allow passage of food nutrients, oxygen in the body thereby allowing exchange of nutrients and oxygen between the body tissues and the blood.

Verdich [7]

Answer:

Coal.

Explanation:

Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

Deserts typically have average daytime temperatures of around 100°F, while the average daytime temperature in tropical rain fore
Lelechka [254]

Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.

Explanation:

In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.
