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.
The three parts that make up paint are pigments, binders and solvents.

I think it’s false but jsjs
Yes. Lions are predators to grass eating species, so without the limitation of said species, there would be less chance for grass to grow as it is eaten more because the prey species are not killed off.
