Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.
<h3>What do you mean by Natural selection?</h3>
Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.
Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.
Scientists hypothesize that oxygen began to accumulate in the Earth's atmosphere after the appearance of living things with the ability to Photosynthesize.

Hypothalamus
Explanation:
is linked to the pituitary gland (both in the brain) which releases stimulating and inhibiting hormones which go to glands which are part of the endocrine system such as the thymus
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>
A. They impede fish migration and spawning
Answer:
Ice caps melting, increased heat causing droughts and wildfires
