Answer: The question is incomplete,below is the complete question.

What are the terms describes the dna–protein complexes that look like beads on a string?

A) Chromatin

B) 30-nanometer fibre

C) Histones

D) Nucleosome

The correct answer is option D

Explanation: A Nucleosome is the basic fundamental unit of a DNA, and the fundamental sub-unit of a Chromatin.

The Nucleosome is the basic packing unit of DNA,it is built from histone proteins. A nucleosome is made up of 8 histones proteins resembling a thread wrapped round a spool.

The smallest bundle of DNA is known as a Nucleosome,a Nucleosome is produced through interaction between DNA and histone proteins.

olga55 [171]

The Bartholin's Glands, which are also known as the vestibular glands are a pair of pea size gland. The location of the Bartholin's gland is postrior to the vaginal orifice.

The main function of these Bartholin's gland is to secrete mucus and to lubricate the vaginal orifice. These gland is homologous to the bulbourethral glands present in the males.

<h3>Hence, the vaginal orifice is lubricated by secretions from the Bartholin's Glands.</h3>

Why are fences put along some beaches ?
kvv77 [185]

The answer is; B

Sometimes winds carry the sand of the beaches causing erosion. The fences act as breakers of this wind erosion. As wind tries to carry the sand, they encounter the fence and 'break'. Therefore, the sand is deposited along the fence forming a sand dune. These dunes also form protection from storm surges.

The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0037 m. calculate the number of molecules inside th
Talja [164]

First, let calculate the volume of the rod shaped-bacteria:

S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3

Now, let's convert the moles into molecules (with Avogadro's law):

0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L

Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)

1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3

so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3

The answer is  2.22 10^ 12 molecules / µm3
