Fats are divided into two major classes, these are saturated and unsaturated fats. Saturated fats refer to those fats that do not have double bonds in their molecular structures while unsaturated fats are those that have double bonds in their molecular structures. Saturated fats are usually solid at room temperature and they are considered to be less health as food compared to unsaturated fats. Unsaturated fats are usually liquids at room temperature and they are considered to be more health than saturated fats. Examples of saturated fats are cream, butter, cheese, pork, lamb, poultry with skin, etc.
<span>The answer is A. Variation in gene pool
Speciation is a formation of a new species during the evolution line.
When there is a variation in a gene pool, a unique combination between genes could be formed during the mating process. This will create an offspring with unique gene pool that will lead to speciation</span>
