<span>The barn owl's right ear opens slightly upward while its left ear opens slightly downward. this difference enables the owl to detect the location of a sound. It would actually depend on the location of where it would be at, and based on this, depending where it would then be located, this would then be able to differentiate where it would be located.</span>
For the answer to the question above, there is no such thing as a non-living organism. Because organisms are only a term for living things.
1. Cellular structure: all living organisms generally have a cellular structure i.e., they are made up of one or more cells.
<span>The protoplasm is the physical basis of life. </span>
<span>There is no such fundamental and structural unit called cell in non-living things. </span>
<span>2. metabolism : The various life processes taking place within the body of an organism is collectively termed metabolism. The metabolic processes can occur only in living organisms and not in nonliving things. </span>
<span>3. growth, repair and death : Growth consists of the living organism absorbing materials entirely different from those that make up its body and convert them into body building substances. Growth in non-living substances such as crystal is at the cost of material similar to that of which it consists. Same substance is added without conversion. </span>
<span>The growth is permanent, irreversible process in living organisms but can be reversed in non-living things. </span>
<span>Growth is different in different parts of the body of an organism. Growth is uniform throughout in the non-living things. </span>
<span>Respiration, nutrition,excretion, movement,irritability, reproduction, life span, death, evolvability are other properties of a living organism.</span>
<h3><u>Answer;</u></h3>
When an area is holoendemic, the HbS allele frequency is between 0.52 and 4.04.
<h3><u>Explanation;</u></h3>
- <em><u>HbS allele is the sickle cell hemoglobin allele that provides immunity to malaria. This is because people with the sickle cell allele have a selective advantage in areas where there is a high incidence of malaria.</u></em>
- Therefore, natural selection will favor the population with HbS allele in a Malaria holoendemic (most individuals are infected) region. The HbS allele frequency in this population is expected to be high.
- After malaria is cured, the frequency of the HbS allele should decrease in regions with a lot of mosquitoes because having one copy of the HbS allele will no longer be advantageous in these regions.
