Your answer would be Phospholipids
Explanation:
I'm not sure about the first two but I think the one about the halite crystal is cubic. :)
This reaction is called a condensation reaction. It is also known as a dehydration reaction.
When three fatty acids become attached to a glycerol molecule, a triglyceride is formed. The fatty acids become attached to the glycerol through a condensation reaction named so because 3 water molecules are formed from the 3 OH groups from the fatty acid chains and 3 H atoms from the glycerol.
The bond formed between the fatty acid chain and the glycerol is called an ester linkage.
The right option is; it interprets signals from the external environment
The peripheral nervous system (PNS) is made up of all parts of the nervous system, except the brain and spinal cord (parts of the central nervous system). The peripheral nervous system functions as a channel through which neural signals are transferred from and to the central nervous system. Two types of neurons (sensory and motor neurons) functions in the PNS. The motor neurons transfer neural signals from the central nervous system directly to various muscles, glands, and organs (effectors) throughout the body.
