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.

Answer:
Energy and nutrients are cycled throughout all the different components of the ecosystem. The non-living components like heat and nutrients are called abiotic factors. Both biotic and abiotic factors contribute to an environment's health. Biotic factors include plant productivity and animal behavior.
Answer.
Actually all of these are involved.
Explanation:
Transcription is the process where genetic material or DNA is copied into RNA by the enzyme RNA polymerase. The transcription unit is made up of a promoter, a protein-coding sequence an attenuation sequence, a termination sequence. The rotein coding sequence contain the structural genes which Consist of two strands which is known as template strand and coding strand. Attenuator sequence can be as a result of stop signal which can also lead to transcription.
