Answer:

Since viruses are typically 20-200 nm in diameter, the Electron Microscope is best for viewing them.

Explanation:

Viruses are very smallest in structure to see, so we can't see them with light microscope. Electron Microscope having higher resolution capacity, so they are best to seeing viruses.

The Electron Microscope using electrons to see specimen instead of lights and an electron detector. Electron behave as light so electron beam helping us to see very small scale specimen.

The Electron which are present on microscope has ability of wave (with a wavelength) that is very smaller than visible light. With the help of this wavelength we can see the distinguish feature of viruses in nanometer.

Electron Microscope are mainly three types:

1) Scanning electron microscope (SEM).

2) Transmission electron microscope (TEM).

3) Scanning Transmission electron microscope (STEM).

If I am not wrong, I believe the answer is Producers. The reason as to why I say that producers is the answer is because in every food chain, there needs to be a base. That base is what provides the starting energy that will later on move up in the food chain.

Blood pressure falls with distance from the heart. Using this information, which of the following properly lists the type of blo
Angelina_Jolie [31]

Answer:

The correct answer will be- arteries→capillaries→veins

Explanation:

The circulation of blood in the closed circulatory system flows through blood vessels. These blood vessels show structural differences in response to the pressure exerted by the blood on the surrounding medium.

The blood pressure varies in the circulatory system because the heart pumps the blood with a greater force, so the blood vessel called arteries which carries the blood from the heart posses thicker walls.

The blood pressure reduces until the blood reaches the organs, the blood pressure reduces. Thus the blood in the capillaries has lower pressure.

When blood exits from the organs back to the heart, then the blood pressure is highly reduced as a result, the veins carry the blood with lower pressure.

Thus, arteries→capillaries→veins are the correct answer.
