In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the β hemoglobin alleles in the human gene pool. 15. If the sickle-cell allele is recessive, what proportion of the population should be susceptible to sicle-cell anemia under typical conditions?

Answers

Answer 1
Answer:

Answer is "0.04 Population"

Explanation:

  • The human body is a remarkable piece of work in which every part has its own function. Each part has a specific structure to best fit its function. When everything is structured (shaped) properly, it should function properly. However, there are many times when parts of the body are misshaped, and the deformed structure no longer allows for the body to function properly
  • The function, or job, of red blood cells is to carry oxygen to all the organs in the body. They also get rid of the carbon dioxide (CO2), a poison in our bodies. They travel through a maze of blood vessels such as veins and arteries. To make for smooth travel through the body, normal red blood cells are shaped like little flexible disks. Their shape allows for them to bend and twist and move around the body in a smooth, fluid movement. Blood cells shaped like sickles can obviously not perform their function as well
  • All red blood cells have a protein in them called hemoglobin (HEE-muh-glow-bin). Hemoglobin is what attaches the oxygen to the cell. A person with sickle cell anemia has some red blood cells that have a different kind of hemoglobin called hemoglobin S. Hemoglobin S causes a red blood cell to be deformed into a sickle shape. A sickle cell is stiff and sticky instead of smooth and flexible
  • Hence the right answer is "0.04 proportion of population should be susceptible to sicle-cell anemia inder typical condition"

Which statement best explains why the stability of the producer population is important to the stability of the entire ecosystem

Answers

Answer:

Producers are responsible for providing energy to the rest of the ecosystem.

Explanation:

Producers are literally the basis of all food chains, if they do not exist, it is impossible for energy to pass from one trophic level to the next.

Producers are represented by plants that, through photosynthesis, produce enough energy to be passed to all living organisms, through the food chain. For this reason, it is important to maintain the stability of the producing population, since the stability of the entire ecosystem depends on it, since it is through it that energy is provided for the rest of the ecosystem.
Producers are responsible for providing energy to the rest of the ecosystem.
