When you listen to your favorite music, what is the order in which the sound approaches and enters your nervous system and is in
kvasek [131]
In the ear, the sound waves enter through the auditory canal and hit the eardrum (tympanic membrane). The eardrum amplifies the sound and the waves move on to the middle ear, where three bones called the ossicles (malleus, incus, and stapes) amplify the sound further and vibrate. Then, the sound waves go to the cochlea where tiny hairs and other receptors turn the sound waves into a nerve impulse. This impulse is sent to the brain via the auditory nerve and interpreted by the brain.

Identify how the deletion of a single nitrogen base in DNA can cause a harmful mutation in an organism.
ra1l [238]

Answer:

B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.

Explanation:

Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.

When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence.  For example, given the code:

GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.

So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.

What substance would need to be added in order to reverse the reaction?
Korvikt [17]
The substance that would be added in order to reverse the reaction would be any substance that is found in the product side. Adding a substance that tends to be a product will shift the equilibrium of the system and will allow the reaction to produce the substances that is found in the reactant side.
