I would appreciate help please thank you

Answer:

When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Answer:

I learned about this, Uhm...

C is the right answer bc igneous rocks cool and form crystals.

Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.

Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.

Hope this helps :)

Complete question:

In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the  concept that natural selection is not random?  

Answer:

The study supports the  concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.  

Explanation:

All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

Answer:

A monosaccharide is the most basic form of carbohydrates. Monosaccharides can by combined through glycosidic bonds to form larger carbohydrates, known as oligosaccharides or polysaccharides.

Explanation:

A monosaccharide is a type of monomer, or molecule that can combine with like molecules to create a larger polymer.

Explanation:

The impact that the movement of the water has in this area, is that the movement of the water has caused the erosion of this land because there is no protection against strong waves.

Marine erosion, also called maritime erosion, is defined as “the process of wear, transport and sedimentation of rocks and coastal soils by erosive agents”. Fundamentally, it can be caused by the action of three factors:

With this information, we can conclude that the impact that the movement of water has in this area is that the movement of water has caused erosion of this land because there is no protection against strong waves.

Answer:

C. There is a 25% chance of short offspring.

Explanation:

In the simplified genotypes of a Punnett square cross, we deal with two genotypes. In this case, we are looking at a cross between Tt and Tt. T is dominant and t is recessive, meaning that someone with any genotype with T in it will be tall.

TT, Tt, and Tt will all produce tall offspring, while tt will produce short offspring.

This means there is a 75% chance of tall offspring, or 3:4.

50% or 2:4 are expected to have the Tt genotype.

Only 1 of the 4 will produce short offspring, which is 25%.

Answer:

Sleet is simply frozen raindrops and occurs when the layer of freezing air along the surface is thicker. This causes the raindrops to freeze before reaching the ground. In addition, ice caused by freezing rain can rapidly add weight to tree branches and power lines, causing them to snap or break
