The atomic number of an atom will always identify the amount of protons in its nucleus. If the atom is neutral, what else is identified by the atomic number? A. the number of neutrons in the atom B. the most common isotope of the atom C. the atomic mass of the atom D. the number of electrons in the atom

Answers

D.The number of electrons in an atom.In an atom,the number of protons and electrons are always the same which is indicated by the atomic number.Since we know that protons have a positive charge, and electrons have a negative charge this suggests that an atom is always neutral as +1-1=0.

The concentration of greenhouse gases in the atmosphere can and does change. Would conditions on Earth be worse if the concentration of gases increased or if it decreased? Use Figure 4-4 to explain your answer.

Answers

Answer:

The concentration of green house gases must be appropriate in order to maintain an optimum temperature on the earth.

More the concentration of gases on earth, the temperature would increase because the green house gases more heat in it.

If the overall green house gas will decrease then also the temperature on the earth will not be adequate for living as it will be too cold.

hence, the balance is maintained only when there is a proper concentration of carbon dioxide in atmosphere.
According to climate scientists the increase in greenhouse gases is negatively impacting the planet and human life by raising the temperature of the planet which is leading to other adverse climate effects. If greenhouse gases were to decrease it could potentially help the situation to elevate some of the pressures currently leading to climate change. However, if greenhouse gases are to increase it will likely have an increasingly negative impact on human life and the homeostasis of the planet.

Whats another name for cytosol

Answers

Another name for cytosol is cytoplasmic matrix. This is the liquid that is found in the cells. It is how the organelles are suspended within the cell.

Another name for cytosol is cytoplasmic matrix. This fluid can be found inside cells. It has to do with how the cell's organelles are held in suspension.

Numerous crucial metabolic processes occur in the cytosol, which also serves as a conduit for the movement of chemicals and ions throughout the cell. It offers a dynamic setting that supports the cellular machinery and enhances the cell's overall functionality. The term "cytoplasmic matrix" refers to the fluid-like substance (cytosol) that provides the cytoplasmic organelles and molecules with their structural support.

In comparison with liquids and gases, solids area. more dense.
b. more easily compressed.
c. less organized.
d. more likely to flow.

Answers

In comparison with liquids and gases, solids are more dense. The answer is letter B. The solid has a more definite shape and volume. The particles are locked into place. It cannot be further compressed due to the bond that exists between the molecules. The kinetic energy of the molecules is close to none because the molecules are so close and so compact with each other. 

Which substance can not be decomposed by a chemical change?A. Ammonia

B. Copper

C. Propanol

D. Water

(P.s, tysm )

Answers

The substance that cannot be decomposed by a chemical change is: B. Copper

What is copper

Copper is an element, and elements cannot be broken down into simpler substances through chemical changes. Chemical changes involve the rearrangement of atoms in molecules, leading to the formation of new substances.

However, in the case of an element like copper, it is composed of only one type of atom (Cu), and it cannot be further broken down into simpler substances by a chemical reaction.
