There are 20 different type of monomers present in proteins.
Amino acids are in reality the monomers of proteins. Out of the 20 amino acids,
only 9 are considered essential. The other 11 are of little use to the humans.
The nine of the essential amino acids required by humans are Tryptophan,
lysine, Histidine, Isoleucine, Valine, Threonine, Phenylalanine, Methionine and
Leucine. The amino acids combine with one another to form different types of
proteins. These proteins satisfy a number of our physical functional needs.
<u>Answer:</u> The concentration of KOH solution is 1.215 M
<u>Explanation:</u>
For the given chemical equation:
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of KOH solution is 1.215 M
Transition metals.
I have to write 20 so this is filler.
The sensory neurons within the olfactory organ are stimulated by Chemicals in the air.
Sensory neurons are the neurons that take up the signal from the receptors to the Central Nervous system (CNS)
Olfactory organ is the organ which is capable to sense smell i.e. Olfaction.
The Chemicals present in the air stimulates the sensory neurons present withing the olfactory organ consisting of olfactory epithelium. The cilia present in the epithelium recognizes the chemical present.
The neurons form connections of neuron to the olfactory bulb.
It is a mass of tissue that is round in shape that comprises of several kinds of cells of neurons that are capable to sense smell. It is necessary to sense smell properly.
Odorants are the compound that consist of an odor which get detected by the sensory neurons to carry out olfaction. They activate olfactory receptors and send signals to olfactory bulb.
