Ribosomes differ from cell to cell/species to species in

If a mature cell or a gamete of a species 'A' contains 4 chromosomes each root cell of the same species of a higher plant will contain

The differences among the species are due to differences in their

Assertion (A) : New species develop from the existing species known as speciation. Reason (R) : Different species can breed together and produce fertile offspring.

The graph shows the oxygen dissociation curves of haemoglobin from two species of mammals, s and T . Which statements could explain the difference in the oxygen dissociation curves of species S and species T ? I. Species T has higher haemoglobin concentration in its red blood cells than species S. II. The haemoglobin in species T has a lower affinity for oxygen than the haemoglobin in species S. III. Species T may be living at a higher altitudes than species S.
