The correct answer is "applying cold compresses to the affected area".

Most of the people stang by a bee or wasp experience a localized reaction and only 3% of the people will exhibit an allergic reaction. The normal localized reaction includes reddening and swelling of the skin, along with a local itching and pain.

Although these reactions will probably start disappearing within a few hours, there are several things that the person could do to alleviate the pain and discomfort. The most important thing to do is to apply ice or cold compresses to the affected area, to reduce the body's inflammatory response.

Which of these statements best describes an interaction between the atmosphere, hydrosphere and biosphere? A. Strong winds blow
Nady [450]

Answer:

D. A hurricane carries ocean water across the coast and damages houses of people.

Explanation:

This question is looking for a statement that shows the interaction of an atmosphere, hydrosphere and biosphere. Firstly, atmosphere refers to the layer of the air that surrounds the earth i.e it pertains to air. Hydrosphere refers to the part of the earth occupied by water bodies e.g sea, river, ocean etc. i.e. it pertains to water.

Biosphere is the part of the earth that has to do with life i.e. it pertains to living organisms e.g plant, animal, human etc.

Based on the definition of each component, option D truly shows the relationship/interaction of the three components mentioned. That is, A hurricane (represent part of the atmosphere because it has to do with air) carries ocean water (represents hydrosphere because it involves water body) across the coast and damages houses of people (represents biosphere because it talks about living humans).
