Answer:
The term gene expression means the process by which the information encoded in our DNA is used to synthesize a functional product, such as a protein molecule or other cell structures.
Explanation:
Answer:
A solid rock becomes soil when it breaks down and combines with water, air, and organic matter.
Answer:
you would see rivers and mountains.
pine peak is the highest point because there are more circles surrounding it and its also named.
it is flowing away from the ocean because fresh water fish have to swim UP river to spawn in the ocean.
i think its 20 but im not sure
Explanation:
i hope this helps :)
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.
