Answer:
Increased frequency of the allele for sickle cell anemia
Explanation:
Sickle cell anemia is fatal in homozygous genotype. The homozygous genotype having two copies of the allele for sickle cell anemia is not favored by natural selection due to its reduced survival success.
However, the heterozygous genotype for sickle cell anemia with one allele for the disease exhibit malaria resistant. The presence of one allele is not fatal for the organisms as the presence of one normal allele ensures the formation of some normal hemoglobin protein and RBCs to support the oxygen delivery to the body parts.
The increased survival success of heterozygous genotype in malaria-prone regions allowed their natural selection. This increased the frequency of allele for the sickle cell anemia in the gene pool of the local population and increased the frequency of heterozygous dominant genotype.
Answer:
The animals living on land warms the egg to produce its baby where as the animals living on water doesn't makes it warm and most of them leaves the egg all alone. The egg which animals on land give are dry where as animals living in waters egg is unique than the animals which produce on land
Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism,
Answer:
Enzymes can also be referred to as catalysts
Explanation:
Enzymes serve as an accelerating factor to the biochemical reactions in living organisms, and as such, they are used to catalyze the important commercial processes of biotechnology.
Derives from the fact that bacteria are exploited by humans in a number of beneficial ways
