CH3- methyl group
COOH- carboxyl group
H2O- just water
NH2- amino goup
OH- hydroxyl group
the answer is H2O
Answer: ionotropic; metabotropic
Explanation:
A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.
Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.
The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
Salt is the Inorganic matter.
Option D.
<h3><u>Explanation:</u></h3>
Organic matters are defined as those compounds of carbon expect the carbonates, bicarbonates, cyanides etc. These compounds were primarily thought to be produced only from the living organisms and were unable to be produced in laboratory. But later they were being produced in laboratory too.
Inorganic compounds are all the compounds except the organic ones.
Here, in the question, we see the compounds -
Protein - it's the polymer of amino acids which contain carbon, and isn't carbonates or bicarbonates, cyanides etc.
Carbohydrates and sugars are also similar to proteins which contain carbon and isn't the exceptions. So they are also the organic compounds.
But salt, commonly table salt is sodium chloride which doesn't contain carbon, so is Inorganic.
<span>The part of the ear where sound wave compressions and
rarefactions cause the eardrum to vibrate is the middle ear. The 8th
nerve in the inner ear actually converts the mechanical energy to electrical
energy for transmitting to the brain. A membrane called the tympanic membrane
separates the middle ear from the outer ear. Whenever a sound reaches the ear,
it creates a sound wave that creates vibration in the eardrum. The pressure
when high pushes the membrane inwards while low pressure sound waves helps the
eardrum to come outwards. </span>
Answer:
The light bulb will have the same mass on the moon as it will on earth. The mass of an object will not change if the gravitational pull on the object changes, but the weight of the object will. For instance, if you measure your mass on Earth and then measure your mass on the moon, your mass will remain the same. The same theory applies to any object with mass.

hope it helps brainliest pls!! :)
