Answer:

Swimmer A has reduced friction

tight kick with pointed toes reduces friction

Also, keeping your legs as tight together as possible helps to reduce friction because it streamlines, or compresses, the legs. And pitting he head down helps to reduce friction.

Keeping the head down helps keep it in alignment with the body, but more importantly, a head down also can help reduce surface or wave drag. There is actually less drag underwater than on the surface of the water (think of a submarine), because we eliminate surface drag.

A would win the race!

In simple terms, friction makes it hard to slide through water, forcing swimmers to expend more energy to achieve higher speeds. ... Maintaining high energy levels helps swimmers move faster and for longer; even a fraction of a second might make the difference between winning and losing a competition.

However, prokaryotes, fungi, and some types of algae are not included in any modern definitions of the Plantae.

Plants are essential to the ecology because they help with the nitrogen cycle, prevent soil erosion, and participate in the water cycle. Although they also create oxygen, plants are a significant source of food. For humans to exist, it is essential that plants flourish.

One of the simplest methods to enhance the environment and enhance your surroundings is to plant a tree. Plants help to prevent soil erosion by filtering contaminants, absorbing carbon dioxide, and releasing oxygen. It will also assist to lessen your carbon footprint if you plant a few trees.

hence, The farmer ceased preserving the land because plants grew over time.

Does your body get all its energy from the sun

Hunter-Best [27]

Indirectly yes.

Plants need sunlight to photosynthesize. We eat the plants/vegetables which give us glucose. Glucose is needed for respiration. One of the products of respiration is energy.

The equation of photosynthesis:
Carbon dioxide + Water ----> Glucose + Oxygen

The equation of respiration:
Oxygen + Glucose ----> Energy + Carbon dioxide + Water
