The correct answer is D: I and II only.
Viruses have protein capsids, which protect their genetic material. This capsid sometimes is covered by viral envelopes which have glycoproteins on their surface. Glycoproteins help in the process of binding to the host cell and infecting it. In this example, virus III has the structure of a bacteriophage and it does not seem to have glycoproteins. Bacteriophages use their tail fibers to attach to the bacterial host and inject their genetic material. On the contrary, viruses I and II have glycoproteins sticking out of their envelopes.

The viruses labeled with I and II in the picture presented below have a viral envelope, an outer layer of the viral particle that contains various glycoproteins.
These structures on the envelope are key factors in virus-cell recognition and viral infection of the cell.

Addition of nutrients to Water by human activity is called​
wolverine [178]

A common way that humans pollute water is through the addition of nutrients (fertilizers and sewage) to water as nonpoint source pollution. These added materials are full of nitrogen and phosphorus, two nutrients that encourage the growth of aquatic producers, such as algae.

If a meal supplies 110 g of carbohydrates, 25 g of protein, 20 g of fat, and the equivalent of 5 g of alcohol, what % of the kca
mars1129 [50]

Answer:

0.058 % kcalories comes from carbohydrate.

Explanation:

1 g of carbohydrtes gives 4 calories, 1 g of protein gives 4 kcalories, 1 gm of fat gives 9 calories and 1 g of alcohol gives 7 calories of energy.

Thus in a meal  that contains 110 g carbohydrates gives 110 x 4 = 440 calories,  25 g protein gives 25 x 4 = 100 calories, 20 g fat gives 20 x 9 = 180 calories and 5 g alcohol gives 5 x 7 =  35 calories.

Total calories in a meal  440+100+180+35 = 755.

Therefore % of carbogydrate will be 440x 100 divided by 755 = 58.27 %

In kcalories % would be 58.27/1000 = 0.5827 %

Why does fast moving or falling water turn white?
aleksley [76]

Answer:

When water is moving fast, it bounces with other particles of water and it jumps and comes back to its normal place, while it jumps, there are tiny air bubbles of water that get between the two layers of water. And when this happens in a very great amount, then the water turns white.

Explanation:

When fast moving water is there, then the water particles bump on to each other, what happens is that as you know, when something bumps to another thing, it bumps and goes away, so same does the water, the water goes away, and then it comes back. but in the between time, tiny air particles and tiny airbubbles become trapped in the middle. When they get trapped, they make a white color.

So that was why, fast moving water turns white.

Thank You!

Have a great day studying!

Please mark me brainliest!
