He could perform some DNA tests that could show how those species were related. For example, genome sequencing could show all the differences in DNA nucleotides. The number of changes could then be multiplied by the rate of mutations and the result would show how species were related.
Answer:
D- The effect of drift on average fitness is not predictable
Explanation:
Genetic drift is a mechanism causing change in allele frequencies in a population from one generation to another. Genetic drift happens by random sampling and the benefit or harm of the allele is not a factor in deciding which allele stays and which is deviated from.
A beneficial allele may be lost, and a harmful allele fixed into the next generation. Genetic drift affects both small and large populations but its effect is more pronounced in small populations.
Since Genetic drift happens by chance and any allele can be selected, the effect of the drift on the fitness of the population cannot be predicted. If a harmful allele is selected, there will be a negative effect on the fitness. On the other hand, if a beneficial allele is selected, there will be a positive effect on the fitness of the population
Answer:
Option E
Explanation:
Polysaccharides are long chains of carbohydrate molecules, specifically polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages.
Monosaccharides are simple sugars, like glucose. Special enzymes bind these small monomers together creating large sugar polymers, or polysaccharides. A polysaccharide is also called a glycan.
Answer: The binomial naming device is the device used to call species. Each species is given a call that includes parts. The first component is the Genus to which the species belongs, and the second component is the species call.
