The enzymes that digest carbohydrates are very specific and can only digest specific glucose monomers of a Polysaccharides. For example our body can digest starch since its made up of α-glucose monomers (the difference of α-glucose and β-glucose is just on the location of the hydroxl group). However <span>Polysaccharides</span> like cellulose are indigestible because cellulose is made up of β-glucose and the enzyme which digests polysaccharides in humans (amylase) cannot detect β-glucose linkages.
Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.
Mutation can cause instant adaptation while natural selection is the process by which adaptation occurs over a series of generations.
Answer: D
Explanation:
Cytokinesis is basically the formation of 2 new cells. C describes metaphase and A and B are talking about cytokinesis in a plant cell because animals don't have cell walls or plates. So the right answer has to be D
