Answer: Option B.
Neural crest and peripheral nervous system.
Explanation:
Neural crest are bilateral paired cells of the neural tube that arise from the ectoderm layer of the embryo. Thesescells move to different part of the body and differentiate into various cell types like melanocytes,cartilage and bone, smooth muscle, craniofacial, neurons, gangalia e.t.c. The neural crest running through neural tube develop into peripheral nervous system after birth. Peripheral nervous system consist of neurons and gangalia outside the nervous system The peripheral nervous system connect the central nervous system to organs, skin and limbs.
Answer:
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
Darwin's finches are a classical example of an adaptive radiation. Their common ancestor arrived on the Galapagos about two million years ago. During the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behaviour.

Answer:
There are Five main compounds but our body need carbohydrate and protein more.
Explanation:
There are five major organic compounds that our body needs for normal metabolic processes. These are- Carbohydrates, lipids, proteins, nucleic acids and high energy compounds. organic compounds are involved in almost all biochemical activities that is related to metabolism. The organic compounds always contain carbon. Carbs act as the source of energy to the body. They converted to glucose, which used in cellular respiration. Lipids act as fatty acids. Proteins have a structural function like keratin in skin and hair. Nucleic acids are large organic compounds that store and process information at the molecular level inside the body cells. High energy compounds like ATP serves as a source of cellular energy.
