"Carbon, because it can bond with many elements to form complex molecules" is the element that <span>is considered the most versatile element in living organisms. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope it helps you.</span>
<span>Your basic lens is the pinhole camera. You can illustrate
a picture to exemplify how the light rays bypass through the hole to outline a picture
on the screen. A lens is a development on the pinhole, but the pinhole result
is still there, defined by the width of the lens. In a camera, the width is
adjustable and that is what the f-stop embodies. A small f-stop means a small
hole and the pinhole effect permits focus in a large range. A large f-stop
means the focus has to be more accurate, and things in front or behind the
focus point are blurred. In a microscope you have no such adjustment, so depth
of focus is always the same meaning that some objects in front of and behind
the object being viewed will also come into view in focus.</span>
A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
