The function performed in F is that,it mixes the food thoroughly with more digestive juices.
The function performed in M is that ,it allows the control of stool.
I think some factors that influence rabbit reproduction is enough food, healthy rabbits, lots and lots of space for them to populate, and very little predators. This should help I'm not exactly sure what you are looking for though sorry. :^)
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.
Variation is number of alleles for the wing color of the peppered moths. The wing color ranges from pure white to pure back.
Selection pressure is predation by birds.
Explanation:
In the wake of the industrial revolution, white-winged peppered moths had a large allelic frequency in the population compared to black-winged peppered moths. However, when the environment changed due to soot produced by industries (making the environment darker) white-winged peppered moths reduced while that of black moths increased.
This is because black moths were able to blend in and camouflage in the dark environment than white-winged peppered moths that stood out to their predators. Black moths, therefore, had an increased chance of reaching adulthood and passing their genes to the next generation. This increased the allelic frequency of black-winged peppered while that of white-winged moths reduced in the population.
