Which of the following statements is incorrect?
Options
- AIsolated metabolic reactions in vitro are not living things but surely living reactions.
- BAll organisms, from the prokaryotes to the most complex eukaryotes have self-consciousness.
- CThe sum total of all the chemical reactions occurring in our body is metabolism.
- DMetabolic reactions can be demonstrated outside the body in cell-free system.
Correct answer
B. All organisms, from the prokaryotes to the most complex eukaryotes have self-consciousness.
Step-by-step solution
Consciousness is a defining property because it is seen in all living organisms from prokaryotes to complex eukaryotes without any exception but self-consciousness is a characteristic feature of human only because a human is the only organism which is aware of himself. All reactions taking place inside the body are collectively called metabolism which is also a defining property of living beings.
