Answer:Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Explanation:
<span>Coal results from the compressed remains of plant matter, while natural gas is the compressed remains of marine organisms. Natural gas was made due to pressure and heat under buried layers of rock over millions of years, while coal was made by heating the compressed remains from magma underneath. </span>
B. X-linked. When traits are more common in males, this means that it is linked to the X chromosome and a dominant trait. In order for the trait to show, it would need one dominant gene. Since males only have one X chromosome, this makes the change of a gene being dominant 50/50. The daughters do not have it because they have the recessive form of the gene on both of their X chromosomes.
Here are your answers:
1. Paleontologist use the technique called "relative dating" which is when scientist compare rocks to determine the age. So if you have a rock which has a similar surface to another rock you could determine the age of that rock. You could also use the technique called the "radiometric dating" by measuring the amount of isotopes in the rock.
2. You can determine the age of a rock by "looking how rough or smooth the rocks are"... so lets say you fine a rock that has many points, sides, and rough edges which means the rock is actually pretty young so it was recently created and most likely a sedimentary rock, but if you find a rock that has smooth sides and no rough edges which would mean the rock is pretty old rocks could go up to thousands of years old and if a rock is that smooth it could be up too a million years old.
Hope this helps!
