In human blood, there is a compound inside the RBCs called haemoglobin which ensures that the muscle will receive enough oxygen during exercise.
<h3><u>Explanation:</u></h3>
In human blood, the red blood corpuscles contain the haemoglobin. Haemoglobin is a iron chelated compound containing porphyrin ring and a globin tail which can establish co-ordinate covalent bond with both oxygen and carbon dioxide. The bonding element depends on the concentration of these two gases. In lungs, where the oxygen concentration is more than carbon dioxide, the haemoglobin bonds with oxygen and brings it to the tissues where carbon dioxide concentration is more. This makes the haemoglobin to release oxygen and bond with carbon dioxide which is brought back to lungs. This is the process by which each and every tissue including the muscles recieve oxygen.
In muscles there is Myoglobin which is another iron-porphyrin compound which has several times more affinity for oxygen than haemoglobin. This helps to extract more oxygen from haemoglobin in muscles.
Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.
This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.
The human activities that could have endangered botana curus is:
Pollution: It lead to slow down the rate of growth of the plant.
Overexploitation: The over use of plant for its medicinal purpose.
Habitat: The natural habitat of the plant has been changed due to various human activities.
