Answer: The question is incomplete therefore, the options are gotten from another websites.
demonstrating?
A. mechanical energy
B. potential energy
C. kinetic energy
D. two of the above
The correct option is C.
Kinetic energy.
Explanation:
It is kinetic energy because the chemical energy stores in food is converted to kinetic energy and this is because kinetic energy is the energy in motion.
When a person is running, the energy the person is using is kinetic energy because is the energy the person possess by virtue of his body in motion and it is the energy required to accelerate a body with mass from rest.
Answer:
Water molecule is present in air these airborne water molecule are called water vapor, when the molecules are present in air they don't normally stick together as the space is too much.
Bill Nye took a giant bottle and covered it with a stopper and started pressurizing it with a pump to make the molecules come closer and become compressed also it increase the temperature even slightly and that warmth will cause the liquid stick with the smoke particles to go back to forming as vapor.
After that he removed the lid then the air inside the bottle is spread out and it will eventually cool also the kinetically energy is also reduced and that cooled air sticks with dust particle which now forms cloud.
This experiment shows how the clouds are formed and the science associated with it.
I’m not sure if there’s options to the question but the answer should be C. prokaryotes convert nitrogen-containing molecules into forms that can't be used by other organisms.
The evidence of common ancestry is based on study of
three parameters; fossils record, homologies of various
organisms, and study of biogeography. Fossils record determines the similarity and differences of
bones as well as shells of different organisms over a given period of time. On the
other hand, studying of homologies involves assessment of mitochondrial DNA and
other proteins with an aim of finding similarity from one organism to
another. Finally, Biogeography is the
assessment of how continental drift might have separated organisms which had
got common ancestry and they were living together.
We can’t predict what will happen when a predator is lost from an ecosystem; there are too many unknown ways that species interact, and the processes take place over scales of tens to thousands of square kilometers. The true effect of a loss can’t be known until years or decades after it has taken place.
