Well, aluminum oxide is an ionic compound as it contains elements categorized as being metal and nonmetal, aluminum is metal and oxygen is nonmetal.

Methane is a covalent compound as it contains elements that are categorized as nonmetals. Hydrogen and carbon.
Also if you took the electronegative values of each element in methane and subtracted the larger one from the smaller one, it would result in a value that is found within a particular range of electronegativity differences that represents it's a covalent, more specifically it can help distinguish between polar covalent and or Nonpolar covalent compounds.

TRUE OR FALSE :Normal cells will not divide unless the nutrients they require are already presen True False
Diano4ka-milaya [45]

Answer:

False

Explanation:

Cell division is a primary procedure by all cells. This process in the life cycle of cells ensures that new cells (daughter cells) are produced. The two major process are; meiosis and mitosis.

Normal cells would divide if the nutrients required are not present, since water is the main nutrient required. But in some cases, the division process may lead to an effect on one or both daughter cells. This effect is called mutation, thereby mutated cells may be produced.

How does mass affect a star's life cycle?
Andre45 [30]

Answer:

<h2>A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. ... As the gas spins faster, it heats up and becomes as a protostar.</h2>
