In farmland areas poor drainage can lead to a buildup of salt in water supplies. A student performed an investigation to study the
effects of salinity on the germination rates of seeds. The student
places seeds in several solutions containing 0% to 3% salt. The
data from this investigation is shown below and suggests that
increased salinity in more areas may lead to a decrease in which of
the following?

food production.

Explanation:

food plants need water to survive. Salt soaks water from a source of it If the slat buildup occurs in that water supply then the plants will not have anything to use to get their glucose to make food. This then leads to the con of the plants dying and the people having a loss of food production.

hope this helped!

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.
