Answer:
Sickle cell anemia refers to a recessive inheritance disorder, in which every individual carries two copies of a gene. In normal individuals, both the copies of the globin gene are normal, and they generate 2 and 4 kb fragments of DNA on digestion by BseR1. A patient with sickle cell anemia is homozygous for the recessive gene and exhibits a mutation in both the copies of a globin gene.
Therefore, BseR1 could not digest the globin gene and generate a single 6Kb fragment of DNA. In a patient acting as a carrier, one copy of a globin gene is mutated and the other is normal. As a consequence, BseR1 digestion generates 6kb of the fragment of DNA (mutated copy) and 4 and 2 kb from the normal copy of a gene.
<span>Driving cars lowers the pH of the oceans by releasing CO that dissolves and forms acid in the oceans. The answer is letter C. CO is soluble in water that is why it readily reacts with sea water to form acid. Forming an acid in the ocean, lowers the dissolve oxygen and thus lowers the pH.</span>
Answer:
Heritable traits that enhance fitness are traits that boost their chances of survival.
Explanation:
Darwinian fitness, the survival of the fittest, says essentially animals with the most beneficial traits tend to out-compete others without the trait. A lot of factors influence how well they compete, but some heritable traits for animals include camouflage (color), limb adaptation, and speed.
