What do you mean by energy?The "ability to do work, which is the ability to exert a force causing the displacement of an object" is the definition of energy. Despite this baffling definition, the meaning is quite straightforward: The only thing that makes things move is energy.
There are many different kinds of energy. These, for instance, are: electrical energy, sound energy, chemical energy, nuclear or atomic energy, mechanical energy, heat energy, gravitational energy, mechanical energy, and so on.
The body's capacity to perform work could be used to define energy. – The joule (J) is the SI unit for energy. or 1 kJ equals 1000 J. Energy forms: Potential energy, kinetic energy, heat energy, chemical energy, and light energy are the various forms.

Identify which plant species you have the most of (big bluestem). Say that this is much higher than all the other species, as most only have a few individuals. You can say that there is 6 times as much big bluestem as there is mountain mint (which is the second most common species).
You have to remember that this only shows the species present in a small area of the prairie, so if you repeated this is another area you could have only 1 big bluestem and 100 mountain mint instead.
Just say what you notice, you don't need to be able to explain why this is the case. :)

Describe two factors that affect the size of surface waves
Answer:
wave height
Explanation:
Wave height is affected by wind speed, wind duration (or how long the wind blows), and fetch, which is the distance over water that the wind blows in a single direction. If wind speed is slow, only small waves result, regardless of wind duration or fetch.

Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

Physical limits on the flow of ______________into and _________of the cell prevent most cells from being too large.
Answer:
materials/out
Explanation:
Physical limits on the flow of materials into and out of the cell prevent most cells from being too large.
The limitation of the kind and amount of materials that flow into and out of the cell prevents the cell from being too large. The function of selectively allowing materials to enter and leave the cell is carried out by the cell membrane. While being permissible to some materials, it shuts some materials off and, thus, the size of the cell is maintained.

Which of the following phrases best describes cancer
Answer:C uncontrolled cell growth caused by mutations in genes that control the cell cycle
Explanation:
Cancer is mutated cell that grew uncontrollably
The phrase that best describes cancer is uncontrolled cell growth caused by mutations in genes that control the cell cycle, hence option C is correct.
Cancer is a broad collection of illnesses that can begin in practically any organ or tissue of the body.
These illnesses are brought on when abnormal cells grow out of control, cross their normal boundaries to infect nearby body parts and/or spread to other organs.
Mutations in the genes that regulate the cell cycle result in uncontrolled cell growth. Cancer cells are unable to recognize or regulate cell division and proliferation. They continue to reproduce as a result.
