Chemoreceptor is a specialized sensory receptor cell, which responds to a chemical substance and generates a biological signal.
The type of chemoreceptor responsible for our sense of smell is called olfactory receptor. It is also known as odorant receptor, these are found in a small patch of tissue high inside the nose. These cells directly connected to the brain.
Answer:
Carbon dioxide has been released by the burning of fossil fuels. This process is increasing the ocean's water temperature resulting in the glacier melting
Explanation:
The carbon dioxide emissions have constantly been on the rise ever since the Industrial Revolution occurred. The burning of the fossil fuels is the main reason why there is such high quantity of this gas released into the atmosphere. The carbon dioxide is a greenhouse gas, thus it contributes to the arming up of the atmosphere. Because the atmosphere is warming up, the water is warming up as well. The higher temperature of the water results in melting of the glaciers, such as Thwaites Glacier. As the process continues, more and more of the glacier will be melted, with the end result being relatively big rise of the sea level.

Answer:
Deletion of two nucleotides.
Explanation:
Every amino acid coded by 3 nucleotides.
12:3=4 (amino acids)
6:3=2 (2 amino acids)
3:3=1 (1 amino acid)
After all of these mutations sequence amino acids change, but after continues stay the same.
Only deletion of 2 nucleotides will completely altered all amino acids encoded without mutation.
