Answer:
This question lacks options, the options are:
A) storing energy
B) catalyzing cellular reactions
C) building tissue
D) storing genetic information
The answer is D.
Explanation:
There are four major biological molecules found in living systems. They are as follows: carbohydrate, protein, lipids and nucleic acids. The biomolecule being described in the question is a NUCLEIC ACID. Nucleic acids are complex biomolecules made up of long chains of monomeric units called NUCLEOTIDES.
Nucleic acids are two in nature; Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). These two nucleic acids are involved in the storage of genetic information in all living organisms. They carry the inheritable genetic information of living organisms.

Answer:
True
Explanation:
The scala vestibuli contain perilymph in which there is a domination of Na+ ion which is K+ in endolymph. endolymph has domination of K+ because they have very large potential as compared to perilymph this is also called endocochlear potential . there is a potential difference of about 150 mV across the stereocillary membranes that drive cations through mechanotransduction channels
