The correct answer is option B. Higher levels of haemoglobin

A higher level of the haemoglobin allows the organism to survive in low oxygen condition. The low oxygen level decreases the amount of oxygen delivered to the cells, to cope up this condition, there is an increase in the haemoglobin content. The increased haemoglobin concentration allows the delivery of  the sufficient amount of oxygen, as the number of haemoglobin increase, the capacity of oxygen carried to the cell is increased.

Select the true statement(s) about chemiosmosis in eukaryotes. To be marked correct, you'll need to select all true statements,
Alexeev081 [22]

Answer:

a. Chemiosmosis requires the formation of an electron gradient.

b. In aerobic eukaryotes, chemiosmosis leads to the production of water and up to 34 ATP.

c. In eukaryotes, chemiosmosis requires that protons diffuse through ATP synthase in the inner mitochondrial membrane.

Explanation:

Chemiosmosis theory has been proposed for understanding the procedure for the production of ATP in eukaryotic organisms. In the process of chemiosmosis the movement of ions takes place across the semi-permeable membrane according to the concentration gradient. In the whole procedure the electrons move through various complexes and electron acceptors and finally reach to the final electron acceptor, the Oxygen. Due to the movement of electrons the energy is released which is used to pump the protons across the membrane.
