Answer:
c) microevolution
Explanation:
Microevolution is the change in allelic frequencies within a population over time.
If natural selection favored birds with beaks and small bodies, that means that the frequency of that phenotype (beak and small body) increased while the frequency of birds with body and large beaks decreased.
In this example we see that in the Darwin's finches population, the allelic frequencies - reflected in the phenotype - changed over time as a consequence of the drought.
They would be metamorphic rocks because they form under high heat and pressure. Sedimentary rocks are formed under high pressure. Igneous rocks are formed under high heat.
The best answer would be "research reasons why species change over long periods of time"
if not i apologize but this is my best guess<span />
A control group is going to be something that you don’t “experiment on or change. It is grown or watched under normal conditions. This way you have a medium to say how things are “supposed” to go.
The experimental group is going to be where you “experiment” and change the normal conditions to see what outcome will occur ( under different conditions then normal )
Explanation:
Solids:
Particles stay close together with a pattern
Particles do not flow freely
Definite shape and definite volume
Liquids:
Particles are closer together (compared to gas) with somewhat of a pattern
Particles flow freely
Somewhat strong attractive forces that hold an indefinite shape
Gas:
Particles spread out without a pattern
Particles flow everywhere (they are like kids on a sugar rush)
Weak attractive forces that hold no shape or volume
Indefinite shape and indefinite volume
Not entirely sure what compressibility is so i skipped that one for all of them
