There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA.
All animals and plants are made of cells. Animal and Plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes.
Answer:
The correct answer is competitive exclusion.
Explanation:
According to the principle of competitive exclusion, the two species, which compete for the exact identical resources cannot coexist stably. Of these two competitors, one will always exhibit a slight advantage over the other, which results in the extinction of the second competitor in the prolonged time.
It can also result in an evolutionary shift of the inferior competitor towards a distinct ecological niche. As an outcome, the competing associated species usually evolve differentiating features in the regions where they both coexist. This helps in mate identification, thus, sustaining the superiority of each species in exploiting somewhat distinct ecological niches.
Enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.
