Answer:

1 .Atom goes to C

2.Proton goes to A

3. Neutron goes to b

Question 4:Protons are a type of subatomic particle with a positive charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron

Question 5:Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus.

Question6:Thomson's model of the atom in 1897 shows that the atom was a sphere of matter, wherein the electrons are mixed inside it. This model does not show the protons and the neurons. On the contrary, the current model that was proposed by Niels Bohr gives us a clearer representation of the structure of an atom.

Question 7:its mass number A is 23.

Question 8: 1 i found the number because hydrogen only has 1 atom so yuh..

I will answer the rest in the comennts:)

Indicate the expected number of Barr bodies in interphase cells of individuals with Klinefelter syndrome; Turner syndrome; and k
madreJ [45]

Answer:

Barr bodies are small bodies that are dark staining bodies that show the inactivated X chromosome, these sex chromatin bodies attach to the membrane of the nucleus of interphase cells.

One less of the total number of X-chromosome (n-1) represents the number of Barr bodies.

Then,

The number of Barr bodies with Klinefelter would be:

Klinefelter (47,XXY): (n-1) = (2-1) = 1 Barr body as here two X chromosome present.

Similarly, for

Turner (45,XO): (n-1) = (1-1) = 0 Barr bodies (X chromosome = 1)

Now, as per the question, the bar bodies for karyotypes given

47,XYY: (n-1) = (1-1) = 0 Barr bodies

47,XXX: (n-1) = (3-1) = 2 Barr bodies

48,XXXX: (n-1) = (4-1) = 3 Barr bodies

Subunits sometimes build up to form amacromolecule. which molecule is least likely to be a subunit of a macromolecule?
zloy xaker [14]

The molecule that is least likely to be a subunit of a macromolecule is the steroids.

<h3>What are macromolecules?</h3>

The term macromolecules refers to those molecules that are large and are composed of smaller subunits that are joined together to form the macromolecule. These subunits are called the monomers of the macromolecule that is under study.

We know that the steroids are already large molecules in themselves thus they can not be joined together to form a bigger molecule.

Hence, the molecule that is least likely to be a subunit of a macromolecule is the steroids.
