Answer: crossing over
during the process of fertilization, a sperm and egg join together to create a zygote. since a sperm had half the number of chromosomes and an egg has half the number of chromosomes, when they join together the zygote had a complete diploid set of chromosomes. the assortment of chromosomes and crossing over promotes genetic variation during the process of reproduction
My favorite animal is the Arctic fox it has very small ears because with big ears very much heat is lost so the small ears cause the fox to lose less heat.

Answer:
Explanation:
The aim of the Hershey and Chase experiment was to show that DNA and not proteins are the genetic material.
Proteins are made up of amino acids which also has a nitrogenous base. Since the whole point of the experiment was to differentiate between the two i.e. show which one is the genetic material, it would be impossible to differentiate between DNA and proteins if the nitrogenous base was labelled.
<h2>X-Ray diffraction</h2>
Explanation:
- x-ray diffraction and the macroscopic shape of crystals.
- X-ray diffraction is a nondestructive method generally utilized for the portrayal of smaller scale crystalline materials. The strategy has been generally applied for stage distinguishing proof, quantitative investigation and the assurance of structural flaws. Lately, applications have been stretched out to new territories, for example, the assurance of reasonably complex gem structures and the extraction of three-dimensional microstructural properties. This is the outcome of the higher goals of current diffractometers, the coming of high-power X-ray sources and the advancement of line-profile displaying ways to deal with conquer the line cover issue emerging from the one-dimensional information contained in a powder diffraction design.
