Answer:
A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. Hydrogen bonds can occur between molecules or within parts of a single molecule.
Answer:
C. tarsal glands: produce tears
Explanation:
The tarsal plate refers to a thick fold of connective tissue that serves as a support to the eyelids. A row of tarsal glands is embedded in each tarsal plate. Tarsal glands are elongated modified sebaceous glands. Also known as meibomian glands, they secrete a fluid that helps keep the eyelids from adhering to each other. These glands do not produce tears. Tears are produced by lacrimal glands present in the lacrimal apparatus.
If the choices are A.C2H6, B.C2H4, OR C.C2H2 then the answer would be B.C2H4 because each carbon atom bonds with two hydrogen atoms and one double carbon bond.
A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate
