B. The effects of warmed water on aquatic life
Explanation:

Polar covalent bonds (because hydrogen and oxygen form polar bonds and are both nonmetals so it's covalent) and hydrogen bonds (because the water molecules are attracted to each other with partial charges, causing specific properties like surface tension).
So in my very bad drawing that I attached in case you're more a visual learner, the d- and d+ show the partial charges of hydrogen and oxygen (making it polar, as the electrons in the bond are more shifted towards oxygen, which is why oxygen has a negative sign) and the yellow dotted line show the hydrogen bonds.
Answer:
a- The paper towel with more thermal energy
Explanation:
The paper towel with a higher temperature is one with more thermal energy.
Temperature is the degree of hotness or coldness of a body. And it is a measure of the average kinetic energy of the particles within a medium or body.
As body gains more thermal energy which is a form of kinetic energy, the average kinetic energy of its particles increases.
This will in turn lead to an increase in the temperature of the substance.
So, the paper towel with more thermal energy will have a higher temperature.
(D) exposure of a photographic plate
