Answer:
G proteins. (Ans. B)
Explanation:
Metabotropic receptors are also called neurotransmitter receptor, they are indirectly linked with ions channels through the signal introductions mechanism on the plasma membrane of the cell & activating G-proteins. The Metabotropic receptor is activated by specific neurotransmitters (is known as a chemical messenger which delivers a signal across a chemical synapse, from 1 nerve cell to another target neuron).
G protein which is also called guanine nucleotide-binding proteins, that behaves as molecular switches inside the cells & they are involved in delivering the signals from stimuli outside the cell to its inside.
Traditionally, some textbooks from the United States used a system of six kingdoms<span> (Animalia, Plantae, Fungi, Protista, Archaea/Archaeabacteria, and Bacteria/Eubacteria) while textbooks in Great Britain, India, Australia, Latin America and other countries used </span><span>five kingdoms</span>
Spread of disease is the answer.

Bottom Strand of DNA. The 1st codon has been done for you.
Remember: There is no thymine in RNA!!
Pesticides may end up in water sources (such as rivers and the sea), as a consequence they end up in the food chain. Not only this, human water systems could be affected, resulting in humans ingesting these pesticides.
Pesticide presence increases as you go up the food chain because more food will be consumed (e.g: The larger fish may eat several small fish who are contaminated with the pesticide).
Example:
Algae (absorbs pesticide)—> small fish —> Larger fish —> Human
