No. Yes phenotypes are important for example those with longer legs can run faster and hence escape predators
But genes also code for unseen proteins
For example, if a disease is introduced those with long legs won't survive but those who have the genes which code for the complimentary antibody have the ability to kill the pathogen and hence survive.
A riparian buffer is usually a piece of land along a water course, where no farming is allowed with the purpose of protecting the water course.
A riparian buffer is important for protection of water quality. Riparian zones help sediments, phosphorous, nitrogen, pesticides and other pollutants from reaching a river or stream.
The root system of plants, shrubs and trees growing on the riparian buffer land stabilize the soil, and thus prevent sediments and pollutants from entering the water body .
The correct answer is that it is warmed and moistened already in nose and mouth, at the very beginning, when it enters our body (answer a).
It needs to be filtered and warmed alredy before it enters further, because our internal organs are delicate and a dry, dirty air would cause damage to our lungs and other organs.
