Answer:
There are four forces of evolution: mutation, gene flow, genetic drift, and natural selection. Mutation creates new genetic variation in a gene pool. Gene flow and genetic drift alter allele frequencies in a gene pool.

Answer: Elephants.
Explanation: The tusks of this organism fits the description of Elephants tusks.
The process that occurs in a cell when there is not enough oxygen
is called fermentation. Fermentation occurs through the process of Anaerobic Respiration,
where instead of using oxygen, organic and inorganic molecules are used as
final electron acceptors. The by-product of this process is usually alcohol,
ethanol, or acetic acids.
<span>
Fermentation is commonly used in lactic acid (in muscles) and alcohol (beers,
whiskey) fermentation where the by-product is ethanol. Yeasts are a common
organism that uses this process, where it convert sugars into alcohols or
acetic acids.</span>
The answer is: D because “purebred” is an offspring of many generations that has every same trait etc.
Answer: Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.
Explanation:
Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population. Sexual reproduction promotes variable gene combinations in a population leading to genetic variation.
