D.a protein that attacks foreign molecules
First is Light. This area in the deep sea, where there is totally no light at all. Creatures survive by producing their own light through chemical reaction, which is called bioluminescence. Second is Food. Since light cannot reach this area anymore, photosynthesis cannot take place. The creatures feed on decaying organisms.
Last is Oxygen. Aphotic region is the coldest region of the sea and have an adequate amount of oxygen.
The best answer is B; heat energy is also known as thermal energy.
Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase
Here is a word equation for the hydrolysis of lactose:
lactose + water → galactose + glucose
Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.
