<u>1. interaction between atmosphere and biosphere.</u>
An example of this interaction would be the way in which plants give out carbon dioxide and absorb oxygen from the air. Plants are able to do so directly from the air through their stomata.
<u>2. interaction between atmosphere and geosphere.</u>
The atmosphere provides the geosphere with the energy necessary for the breakdown of rocks and erosion. The geosphere reflects the energy of the sun back to the atmosphere.
<u>3. interaction between hydrosphere and atmosphere.</u>
The water cycle is a good example of this interaction, as well as the weather phenomena that come from it (rain, snow, etc.)
<u>4. interaction between hydrosphere and geosphere.</u>
An example of such an interaction would be the erosion that is caused by water in rivers and waterfalls.
Answer: it would be natural selection
Explanation:
You will need to complete a Punnett square to answer this. Let's say tongue rolling is R and non-rollers are r. The heterozygous roller would be Rr and the non-roller would be rr.
Rr x rr
That yields two offspring with Rr (rollers) and two rr (non-rollers). The ratio is 2:2 or 50%. See the attached image for the completed Punnett square.
Alcohol use of course. Especially when driven by peer pressure. Stay Safe Hope this helps
