Answer:
Option-B
Explanation:
The brain is an organ composed of neurons which controls all the voluntary and involuntary of animals. In humans, the brain is located in the skull where the brain is suspended in a fluid called cerebrospinal fluid.
As humans ages and becomes old aged, the neurons in the brain losing their ability to perform their function, if they are lost they cannot be regenerated.
The lesions appear on the white matter of the brain and the brain shrink. Due to these known and other unknown features, the process controlled by these neurons become inadequate and shows slower brain processing and weak memory.
Thus, Option-B is the correct answer.
Answer: Hey again!
Option (a) is the correct answer.
Explanation:
Elemental form of carbon means the pure form of carbon, that is, carbon is present in its natural form.
An elemental form also means that the pure atoms are not attached to any other atom.
For example, diamond is an allotrope of carbon in which there are only carbon atoms attached to each other and no other atom is present in it.
Whereas methane has carbon and hydrogen atoms attached to each other therefore, it is not an elemental carbon. And proteins include different atoms attached to each other.
Thus, we can conclude that diamond is an example of elemental carbon.
