Answer:
chromosomes of a cell are in the cell nucleus. They carry the genetic information. Chromosomes are made up of DNA and protein combined as chromatin. Each chromosome contains many genes. Chromosomes come in pairs: one set from the mother; the other set from the father.
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:
These are the "Light Phase Reactions" of photosynthesis, which produce two high energy chemical products, namely NADPH and ATP. ... And in the end, the plants have utilized the energy of sunlight to produce glucose (and ultimately other carbohydrates, proteins and fats) and oxygen from water and carbon dioxide.

Answer:
nature and nurture
Explanation:
According to my research on studies conducted by anthropologists, I can say that based on the information provided within the question this demonstrates the intimate connection between nature and nurture. This can be said because in the question it illustrates how the advanced ability to hunt animals (nature) was a main aspect of our change in diet and ability to adapt rapidly (nurture).
