Answer:
<em><u>The answer is</u></em>: <u>Folded, fault block, volcanic.</u>
Explanation:
<u>The main types of mountains are</u>: Folded, fault block, volcanic and upwarped.
Folded mountains. These types of mountains tend to change constantly depending on their complexity, however they always conform to the basic type.
Volcanic mountains. It is about the mountains that come to form when a volcano erupts.
Domes. These mountains are created by domed strata, as a granitic intrusion is generated.
Mountains in block. These are large-scale structural failures. These inside are usually folded and tend to have failures.
Plateau mountains. These are created when there is activity in the deepest of the earth's crust. They are formed with the deep channels that the current water produces, where the rivers can cut any table regardless of their depth, thus producing high-rise mountains.
<em><u>The answer is</u></em>: <u>Folded, fault block, volcanic.</u>
It is true that it is possible for a population to not evolve for a while.
There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.
There are 5 Hardy-Weinberg assumptions:
- no mutation
- random mating
- no gene flow
- infinite population size
- and no selection (natural nor forced).
You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.
For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.
Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

Descending tracts are the pathways by which motor
signals are pass through from the brain to lower motor neurones. Thus, all
the neurones within the descending motor system are classed as upper motor
neurones. The lower motor neurones then directly innervate muscles to produce
movement. Their cell bodies are found in the cerebral cortex or the brain stem,
with their axons remaining within the CNS.
Answer:
mid ocean ridges forms because it is responsible for dividing the ocean's.
Answer:
C) an interneuron
Explanation:
A reflex arc is a neural pathway that controls a reflex action. In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through an interneuron because an interneuron enables communications (i.e a pathway for information passage) between a sensory neuron and motor neuron. They play vital roles in reflex actions, neuronal oscillations, neurogenesis in an adult mammalian vertebrate brain.
