Which of the following best explains why the diversity of organisms decreases as you move from shallow seas to deep oceans? The levels of oxygen in the deep ocean are too high for many organisms to thrive.
The low temperatures of the deep ocean would freeze most organisms.
The salinity of the deep ocean is too high for most organisms to live.
The lack of sunlight in the deep ocean limits the types of organisms that can survive.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this

what are the options

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
