7) When there is pressure, tectonic plates can shift, which moves some of the lithosphere. It cooperates with the mantle of the Earth because the crust floats on top of it.
8)Magnets have a north and South Pole. Opposites attract while similar poles repel. Magnets can be cut in half and still have a north and South Pole. The earth is a magnet.
9) Compasses are magnets that have an attraction towards the Sun. By observing the time, the Suns position in the sky, and a compass, people can navigate much easier.
10) The steepness of the platform, the height of the platform, and the weight of the object.
12) Heat can travel in 3 ways; conduction, the transfer of heat through physical touch, such as touching a hot metal spoon; convection, there transfer of heat through liquid or gasses, and radiation, the transfer of heat through waves. An example of radiation is the heat from the sun or a fire.

Which prediction will most likely describe how friction will affect her findings? The distance for Trial 3 will be greater than
Juliette [100K]

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.

Explain how the random alignment of homologous chromosomes during metaphase I
borishaifa [10]

The randomness in the alignment of recombined chromosomes at the metaphase plate, coupled with the crossing over events between nonsister chromatids, are responsible for much of the genetic variation in the offspring. To clarify this further, remember that the homologous chromosomes of a sexually reproducing organism are originally inherited as two separate sets, one from each parent. Using humans as an example, one set of 23 chromosomes is present in the egg donated by the mother. The father provides the other set of 23 chromosomes in the sperm that fertilizes the egg. Every cell of the multicellular offspring has copies of the original two sets of homologous chromosomes. In prophase I of meiosis, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate. Because there is an equal chance that a microtubule fiber will encounter a maternally or paternally inherited chromosome, the arrangement of the tetrads at the metaphase plate is random. Thus, any maternally inherited chromosome may face either pole. Likewise, any paternally inherited chromosome may also face either pole. The orientation of each tetrad is independent of the orientation of the other 22 tetrads.
