Answer:
The correct answer is - molars.
Explanation:
Mechanical digestion takes place inside the mouth of an organism by the process called masticating with the help of teeth. There are four types of teeth in the mouth all help in the digestion of the feed incisor cuts the food, canines tear the food, premolars, and molars chew or masticate the food.
The main and major tooth that helps in mechanical digestion is the molar to chew food so it can mix with the saliva to make bolus and chemical digestion.
Factors that affect natural selection include variability among all, reproduction and heredity.because the genetic variability of these species may express genes that are not conducive to the evolution of the species
<h3>What factors affect natural selection?</h3>
For natural selection to occur, there are some factors:
- variability among all
- reproduction
- and heredity.
Variability between substances: Organisms of the same species have variations in their characteristics.
With this information, we can conclude that factors that affect natural selection include variability among all, reproduction and heredity.
