Which is the independent variable in the graph of the u. s. population 1800-1900? population straight lines united states years

Years

Explanation:

An independent variable is the variable that is changed or controlled during an experiment, and this is done to test the effects on the dependent variable. So the dependent variable is affected by the independent variable and it is being tested and measured in a scientific experiment.

In the graph, time or years is the independent variable because it is not caused by the experiment. It just exists and it can cause a change in population (the dependent variable). As the years go by, the size of the population can increase or decrease, so it depends on the time elapsed.

halogen, any of the six nonmetallic elements that constitute group 17 (group viia) of the periodic table. the halogen elements are fluorine (f), chlorine (cl), bromine (br), iodine (i), astatine (at), and tennessine (ts).

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
