The term "hydrophillic" literally means water loving.
Hydrophillic substances are those that have an affinity of water, meaning they are easily dissolved and absorbed in water. Polar substances, those which have charges on the atoms of their molecules, tend to be hydrophillic due to the fact that water itself is a polar substance.
The answer is C. solid iron and nickel
Answer:
Transparency is the <u><em>opacity of the atmosphere</em></u>, or how clear it is. Moisture and humidity lower the transparency, as does smoke or other kinds of pollution. It’s not entirely unlike light pollution in that it washes out the fainter details of astronomical targets. In fact, poor transparency typically makes light pollution worse because it scatters the light around instead of letting it escape into space away from your cameras and optics.
Transparency usually gets better with altitude, because you're looking through less air. That's why high altitudes are prized for observatories and star parties.
Transparency is also usually very good after a rainstorm has come through to clear all of the particulates out of the air. This is reason number one I figured my second friend had it right at the star party.
Seeing, on the other hand, is a measure of <u><em>atmospheric turbulence</em></u>. We know that if we take a photo of a fast-moving subject, such as at a sporting event, with a low shutter speed, we'll get a blurry image. So what happens when you have to take a very long dark-sky photo and the stars are jumping all about due to atmospheric turbulence? That’s right, blurry stars and deep sky objects.
Seeing is typically better in places where the geography is very flat. The air masses moving over the land encounter few obstacles and flow more smoothly (sometimes called a laminar flow). In Florida, the winds coming over the mountains gets all mixed up like a creek flowing over big boulders, which makes for terrible seeing.

Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.
Explanation:
They are among the only types of organisms that get their energy from a non-living thing, and they give energy to Primary consumers, which give energy to secondary consumers, which give energy to tertiary consumers, which can give energy to decomposers, etc.
