Which one are you asking about
Answer:
False
Explanation:
A generator converts mechanical energy into electrical energy
''The plasma membrane allows some molecular species to enter and excludes others. It is therefore referred to as a SEMIPERMEABLE MEMBRAINE.''
Answer:
A. Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
Explanation:
Energy, as stated in this question, can be of two types namely: kinetic energy and potential energy. Kinetic energy is the energy due to motion i.e the energy used to transport solute etc.
On the other hand, potential energy is the energy due to position like the energy stored in the covalent bonds of a molecule. Based on this question, the fact that triglycerides (a type of lipid) store about twice as much energy as polysaccharides (carbohydrate) is evidence that POTENTIAL ENERGY is stored in covalent bonds.
