Answer:
Radiometric dating methods
Explanation:
Geologists usually use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon to find the age of fossils.
<span>An element is a substance that cannot be broken into other substances further.An element is composed of one type of atoms all over. Like a molecule can be divided into atoms further. For example, Water is a molecule which is made up of Oxygen (O), Hydrogen (H). Here, Oxygen and Hydrogen are elements and cannot be further broken down into other substances.</span><span />
The disorder where the grandfather and the grandchild are affected is related with the X chromosome and is called Sex linked or X linked disorder.
<h3><u>Explanation:</u></h3>
All the sex linked disorders are recessive in character i.e the normal allele is dominant over the mutated allele. In females, there are 2 X chromosomes, so the mutated allele is only expressed when there are both the mutated alleles, else its masked by the dominant normal allele. But in males, there's only one X chromosome, so if a mutated allele is present, it's readily expressed.
If the Grandfather is diseased, then he must have that mutated allele in X chromosome. Through reproduction, its received by the mother, but she is normal because the other allele received from grandmother was normal. But mother has one of the X chromosomes with mutated allele, which is received by the grandson who again becomes diseased.
So the disorder must be X linked disorder
Oil and natural gas were created by the squeezing of Plankton over millions of years. Oil & Gas were formed (over millions of years) from organic matter like plankton, plants and other life forms. Over time, sand, sediment and rock buried the organic matter and it eventually formed large quantities of fuels.
