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.
The answer is c because many things are losing their habitat and food sources
eel- electrical energy
bat- mechanical energy
polar bear- thermal energy
firefly- radiant energy
Yes. Some mammals may have less hair/fur, but all mammals do. It is a defining characteristic of a mammal.
Answer: A. sorE encodes a gene that increases I. hockious virulence
Explanation:
Notice that at the start of the study, there were 10 times mutant gene lacking sorE compared to the wild type. After 24 hours, it reduced to 5 times compared to the wild type, this is an indication that sorE is a virulence gene and it's absence reduces the virulence of the bacteria.
