In one type of cell division, a single cell forms two new cells. This process is called mitosis. What is a reason that human skin cells frequently undergo mitosis?

Answer:

A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.

Answer:

2C2H2+5O2--->4CO2+2H2O

Explanation:

.....................

Answer:

So the atomic number increases with each element. The atomic mass is the sum of the protons and neutrons. As the atomic number increases it causes an increase in the atomic mass. However sometimes there is not a corresponding increase in the number of neutrons...

:)) good luck!!!

Answer:

They have mobile charged particles.

Explanation:

Plasma refers to very hot matter such that the electrons in matter are ripped away from the atoms leading to the formation of an ionized gas.

We know that the carriers of electricity are charged particles. Any state of matter that has an abundance of charge carriers will definitely be a good conductor of electricity.

Therefore, plasmas are good conductors of electricity because they have a lot of mobile charged particles.

Answer:

yes

Explanation:

Yes, electricity and light can bring reversible and irreversible changes. Light : Reversible change - The light illuminate it's surrounding's environment which is reversible when we turn off the source of the light. ... And,this reaction is an irreversible change

Answer:

The Eukaryotic cell has a nucleus

Explanation:

Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Answer:

27

Explanation:

Answer:

The atomic number of Nitrogen is seven. So it contains seven protons and seven electrons in neutral form. Also, the electronic configuration cited above contains seven electrons among which two electrons are present in first shell and five electrons are present in valence shell respectively.

Answer: B

Explanation: All you have to do to find out if an equation is balanced is count the number of atoms on each side. To be balanced, they must be equal.

In case you didn’t know: The number in front of an element or compound means that you will multiply. For instance, 2AlBr3 would have 2 Al atoms and 6 Br atoms. The subscript number just means how many atoms there are in that compound.

If it interests you, you could check out Maxwell's demon. If he is not in operation (and he likely isn't), then the answer is D.

Heat always transfers from hot to cold -- at least at beginning levels of chemistry.

Answer:

W X Z Y. It is the strongest to the least

Answer:

False

Explanation:

The statement is false because the volume of an irregular object can either be measured by the use of a measuring cylinder or an overflowing jar. That's the standard method of measuring irregular objects volume.

Answer:

MgCl2 + Na2O ---> 2NaCl + MgO

Answer:

Particles of objects have both kinetic and potential energy. Because particles are constantly in motion, they have kinetic energy. These particles are arranged in specific ways in different objects. Therefore, they also have potential energy.

Answer:

Rutherford's experiment led to the rejection of JJ Thomson's raisin bundle model. In the experiment, a thin gold strip was bombarded with alpha particles. According to Thomson's atomic model, all alpha particles should have passed through the strip, but in this experiment it was found that some of the particles were reflected backwards. Based on his experiment, Rutherford published the result that almost the entire mass of an atom is concentrated in its nucleus. Rutherford's atomic model was later improved by Niels Bohr, who published the Bohr model.

Answer:

Solar energy is energy from the sun converting it to thermal or electric energy. It is renewable resource meaning it will never die out. It is also called radiant energy.
