Answer:
The correct answer is the second option axon.
Explanation:
Neurons or nerve cells is a cell that transfers electrical signals. Nerve cells are the structural and functional units of the human nervous system. Every nerve cell is made up of 3 parts, a cell body called soma, dendrites and an axon.
The soma or cell body forms an elongated projection, called axon. Axon is responsible for sending electrochemical signals with the help of elaborate ion transport. Some nerve cells have a myelin sheath covering around the axon to facilitate signals faster.
Thus, the correct answer is the second option, Axon.
Answer:A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. ... Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral.
Coastal oceans are commonly defined as the areas from the shoreline to the outer edge of the continental margin. They connect the continents to the open ocean and serve as a link for transporting organic and inorganic, natural and anthropogenic material from land to sea.
Coastal oceans in tropical areas have similar characteristics to their temperate counterparts. ... Coral reefs are biologically diverse and rich habitats that occur in relatively nutrient-poor environments along coastlines. Areas that have too many nutrients often harbor too much algal growth to sustain coral growth.,
The first organic compounds may have been nucleotides and make up nucleotides. Nucleotides bond together to form RNA or DNA. RNA and DNA make up genetic codes. So all of these make up each other in a sort of chain or order.
