Explanation:

It is known that each atom consists of three sub-atomic particles which are protons, neutrons and electrons.

And, inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.

Protons hold a positive charge, neutrons hold no charge and electrons hold a negative charge.

As due to the like charges of protons they tend to repel each other but a force stronger than the force of repulsion helps in binding the protons and neutrons together.

This force is known as nuclear binding energy.

Therefore, we can conclude that neutrons are the other particles which is found in the nucleus and separates protons so that the strong force can hold the nucleus together.

How many molecules of water are released during the polymerization of a 20 monomer-long cellulose molecule?
Alborosie

Answer:

  • <em>During the polymerization of a 20 monomer-long cellulose molecule,</em> <u>19 molecules of water are released.</u>

<u></u>

Explanation:

In simple terms, <em>cellulose </em>is the biopolymer formed by many glucose units. This is cellulose is the polymer and glucose is the monomer.

To have a <em>20 monomer-long cellulose molecule</em>, 20 monomers have been chemically bonded by reacting 19 times, as it is explained in the next paragrpahs, and so 19 molecules of water have been released.

You can imaging the polymerization process as a step-by-step reaction in which the first step is the condensation reaction of one glucose molelecule to produce a 2 monomer-long chain, with the release of one molecule of water: the second step would be the condensation reaction between the 2 monomer-long chain with another glucose molecule, with the release of an additional molecule of water, and so on, until 19 condensation reactions happen, to obtain the 20 monomer-long cellulose molecule.

Condensation is the loss of water in a chemical reaction.

When two glucose molecules react together, condensation occurs. One OH group from each glucose molecule come together, the OH from one glucose molecule combines with the H part of the OH from the other glucose molecule, to form H₂O (water that is released).

The two glucose molecules (monomers) will form one bigger molecule where the two glucose monomers are bonded through the oxygen atom that did not form part of the water molecule released.

Then, a 20-monomer chain means 19 condenstation reactions, with the release of 19 molecules of water.

Do all cells have the same internal structures
professor190 [17]

Answer:

No

Explanation:

Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells. ... Animal cells each have a centrosome and lysosomes, whereas plant cells do not.
