In humans, the embryonic and the fetal forms of haemoglobin have a higher affinity for oxygen than that of adults this is because non-identical genes produce different versions of globin during development. So the correct option is A.
<h3>What is meant by oxygen affinity? </h3><h3> </h3>
The amount of oxygen delivered to the cells will depend on the haemoglobin's oxygen affinity.
Oxygen affinity is defined as the relationship between the saturation of haemoglobin oxygen, represented by SaO2 and the oxygen tension, represented by PaO2. This relationship is plotted by a dissociation curve which is S-shaped.
Thus, in the embryonic the fetal form, haemoglobin has a higher affinity for oxygen.
Therefore the correct option is A.

The graph that best shows the general relationship between the temperature of a gas and the speed of the molecules in that gas is B.
<h3>What is kinetic energy?</h3>
Kinetic energy is the energy that an object or particle has as a result of its motion. When work transferring energy, is done on an object by applying a net force, the object accelerates and goes under kinetic energy.
The missing graphs are attached as image.
The average kinetic energy of gas molecules is
K∝T
So as per above equation, K-T graph is a straight line having a finite slope and passing through the origin.
Thus, option B is correct.

Explanation:
The right answer is the dark reaction would stop happening.
The Calvin cycle (or dark reactions, independent of the sunlight) makes it possible to manufacture glucose, an energy molecule, from carbon dioxide. This is called carbon fixation.There are three reactions of this cycle take place in the stroma of chloroplasts: the first of which is the fixation of carbon dioxide. which is a limiting step in this cycle.If a substance other than the components of the dark reactions absorbs and uses carbon dioxide, the carbon cycle will not be able to occur for lack of one of these ingredients which is the CO2.
