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).

What generally happens to the number of leaves as the leaf surface area decreases?
likoan [24]

As the leaf surface area decreases ; Number of leaves increase inmost plants.

As the leaf surface area increases, the rate of transpiration increases as well because leaves with large surface areas have bigger stomata. also the smaller the leave surface area of a plant/tree the denser the leaves the plants/tree will have.

Trees with tiny leaves tend to have a lot of leaves because of the decrease transpiration rate occurring in the leaves of the plants .

Hence we can conclude that what generally happens to the number of leaves as leaf surface area decrease is number of leaves increases in most plants.

Large molecules, such as glucose, that cannot cross the lipid bilayer can still move across the membrane through a type of passi
harkovskaia [24]
Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.

The correct answer would be D.

After many generations, only those with genes suitable to live in harsh environments can live. These genes are passed onto their offspring and then we see a rise in antibiotic resistant strains of bacteria such as Methicillin Resistant Staphylococcus Aureus (MRSA).
