Answer:

B

Explanation:

A nucleosome is a section of DNA that is wrapped around a core of proteins. Inside the nucleus, DNA forms a complex with proteins called chromatin, which allows the DNA to be condensed into a smaller volume. When the chromatin is extended and viewed under a microscope, the structure resembles beads on a string. Each of these tiny beads is a called a nucleosome and has a diameter of approximately 11 nm. The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4. The chain of nucleosomes is then compacted further and forms a highly organized complex of DNA and protein called a chromosome.

EastWind [94]

The bone that is situated next to the eardrum is called the malleus.

The bone that sits next to the oval window is called the stapes.

Given,

The bone that is situated next to the eardrum is called the __________; the bone that sits next to the oval window is called the __________.

We need to fill in the blanks.

<h3>What are eardrums and their parts?</h3>

The eardrum is a transparent gray membrane and there is a middle ear

bone called the malleus attached to the center part of the drum.

The space inside the ear drum is called the middle ear.

The three smallest bones of the body are found in the middle ear.

They are:

- The hammer (malleus)

It is attached to the eardrum.

- The anvil (incus)

It is in the middle of the chain of bones.

- The Stirrup (stapes)

It is attached to the membrane-covered opening that connects the middle ear with the inner ear (oval window)

Thus

The bone that is situated next to the eardrum is called the malleus.

The bone that sits next to the oval window is called the stapes.
