The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.
If she consumes protein without having to exercise, there
will be a presence of excess amino acids and by having this on her diet, the
amino acids will likely go through deamination in the liver of Marla as they
are excess and are unused.
Habitat is where it lives, and it's niche is what other organisms it interacts with,what it eats, basically its job in an environment . Think of habitat as the address of the organisms house and the niche kinda like the job it has.

</span>A biome is composed of various diverging ecosystems that relates with the community. Biomes can either be deserts, grassland, savanna, tropical rain forest, taiga, boreal and etc. <span>An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. </span>
Answer: Unnatural occurrences
Explanation:
Unnatural occurrences, can have the MOST significant impact on any ecosystem. Energy moves through the plants and the animals in an ecosystem.
