Answer:
Grass - grasshopper- man - bacteria.
Grass - rabbit- man - maggot.
Grass - cow - man - bacteria.
Explanation:
In these food chains, grass is the producer that provides food to primary consumer or herbivores such as grasshopper, cow and rabbit. These primary consumers are the food of secondary consumer such as human while when human die, it become the food of worms and decomposers such as maggot, bacteria etc. the nutrients releases by decomposers are used by producers for the production of food for themselves.
Mutation is random because there is really no way of knowing whether a child will inherit it, whereas natural selection is predisposed in either parent.
Answer:
Biogeographic isolation is the separation of organisms of a species through geographical or biological forces.
Explanation:
All of the factors are responsible for unloading of oxygen from the hemoglobin molecule except the increase in partial pressure of oxygen.
Because the affinity of haemoglobin for binding oxygen increases as partial pressure of oxygen rises.
<h3>What is Haemoglobin?</h3>
Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs.
<h3>What are factors that affect Haemoglobin's affinity for oxygen?</h3>
- When used as an oxygen transporter, hemoglobin can carry about 65 times as much oxygen as simple solution in plasma could.
- A cooperative oxygen-hemoglobin affinity is produced by conformational changes in the molecule.
- The oxygen-hemoglobin dissociation curve's sigmoidal form reflects this characteristic.
- Temperature, hydrogen ions, carbon dioxide, and intraerythrocytic 2,3-DPG all have an impact on hemoglobin's affinity, and they all interact with one another.

Our skin cells divide rapidly in order to maintain a protective barrier against infection.The outer skin layer is called the epidermis and contains mostly dead cells that contain keratin.Keratin is a tough fibrous protein found in hair,skin and calluses and acts as a protective coating.The epidermis cells are constantly undergoing mitosis so the outer dead cells containing keratin are rapidly replaced as they fall off, which occurs after so many days.Then the newer living cells start producing keratin,lose their cellular contents,then die and the cycle goes on.The skin acts as a barrier to infection,therefore,it's constantly renewed and repaired.
