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:
Answer:
Multicellular organism is the example of complexity of the natural world.
Explanation:
Multicellular organism such as human which is made of billions of cell. Each cell perform a specific function. The function of one organ is different from the other organ. For example, brain of human is made of millions of neurons which takes instructions from brain to the organs and bring messages from organs to the nervous system in the form of electrical impulses. In short every system in our body is full of complexity.
Answer:
Seaweed (producer) → Shrimp (primary consumer)→ Crab (secondary consumer) → Octopus (tertiary consumer)
Explanation:
In a food chain, there are organisms of different trophic levels present. Food chain, the chain or linear network or representation of a line of the food web that always starts with a producer as sea-weed in the given food chain and ends with a predator or third or highest consumer which is Octopus here and in between the different level of consumers from the primary consumer that depends on the producers and secondary consumer depends on primary and so on.
Seaweed (producer) → Shrimp (primary consumer)→ Crab (secondary consumer) → Octopus (tertiary consumer)
Answer:
Mammal
Explanation:
A mammal is any any animal that is warm-blooded, gets milk from its mother, and is born alive, etc. Therefore a Cetacean should be considered a mammal.
