How do you describe this solution?
How do you describe this solution? A solution is a homogeneous mixture of two or more substances. A solution consists of a solute and a solvent. The solute is the substance that is dissolved in the solvent. The amount of solute that can be dissolved in solvent is called its solubility. What are the three […]
Why does one oxygen bond with two hydrogen atoms form water?
Why does one oxygen bond with two hydrogen atoms form water? When two hydrogen atoms come close enough to an oxygen atoms, their electrons are attracted to the proton of the other atom. Because there is both a strong enough attraction between atoms and room for electrons in the outer energy levels of the atoms, […]
What do cells need to maintain homeostasis?
What do cells need to maintain homeostasis? One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins. Why do we need to maintain […]

What is the name of the variable that you decide to change in an experiment?
What is the name of the variable that you decide to change in an experiment? Independent and dependent variables in experiments In experimental research, the independent variable is manipulated or changed by the experimenter to measure the effect of this change on the dependent variable. Why do we use constant variables? Constants are useful for […]
