Carbohydrates are the primary source of energy for the human body. if your body lacks enzymes that break down carbohydrates, it would be unable to get (amino acid molecules, fatty acid molecules, sugar molecules) for energy production. If you lacked the enzyme to digest proteins, you may not absorb enough (amino acids, simple sugars, fats).

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

Sorry i dont understand the question can you rephase it?
