Answer:
a. more widespread in the body and affect distant targets.
Explanation:
Hormones are released into the blood by the dustless endocrine glands and the circulating blood delivers hormones to cells throughout the body. Therefore, hormones affect the distantly located cells throughout the body. For instance, growth hormone released by pituitary gland affects soft and hard tissues throughout the body.
On the other hand, the nervous system release neurotransmitters that affect the postsynaptic neuron or the muscle or gland cells present close to the site of their release. Target cells of neurotransmitters are more limited and include muscle (smooth, cardiac, and skeletal) cells, gland cells, and other neurons only.
Carbon is the atom, which is necessarily find in the living organism.
All the living organisms are made up of biomolecules. All the biomolecules are organic compounds. The substance cannot be consider as living, if it lacks nucleic acids. There are two types of nucleic acids DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), both have a structure made up of carbon rings and chains.
Other than nucleic acids, proteins, enzymes, hormones etc are also made up of carbon. So, all the living cells, or dead remain of organism must have carbon atom.
Hence, the correct answer is option D. carbon.
