Artificial selection cannot occur without inherited variation.
Explanation:
Artificial selection is the *process of breeding animals and cultivating plant which have certain desirable inherited characteristics*. It is an intentional way of selection,it is different from natural selection.
In Artificial selection, Animals bred or plants that are cultivated at home garden do not occur exactly the way they are in the wild. They are the result of many centuri of selection process by humans. Man has stipulated such plants/Animal by *selecting out undesired characters to ensure higher yields of resistance*, wherefore inherited traits(variations) are used in the selection process.
*Artificial selection cannot occur without inherited variation because the inherited traits/variation could be adaptations that will help the specie to survive*.
Adaptations can lead to the survival of an organism because it lets them adapt to there environments and helps them survive. Evolution determines the course of a organisms history by showing how species has evolved into what they are now.
The plasma membrane is made up by a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. Only relatively small, non- polar materials can easily move through the lipid bilayer of the plasma membrane.
as we all know, diabetes can only be prevented by eating very very very less sugar. Diabetes type 1 and 2 can be prevented both by eating sugar free meals
