Explanation:

Electrical energy - The communication of neurons with each other takes place at synapses. Synapses are of two types i.e. chemical and electrical. A signal transduction process by a neuron uses electrical energy. In electrical synapse, flow of ions between cells takes place.

Gravitational potential energy - It is the energy possessed by an object when it is placed at some height. It is given by :

PE = mgh

The energy used when "a ball is at the top of a hill" is gravitational potential energy.

Mechanical energy - It is the total energy i.e. it is the combination of gravitational potential energy and kinetic energy.

The flexing of an arm muscle is an example of mechanical energy.

What is the source of carbon for the organisms of food chains?

murzikaleks [220]

Answer:

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

If a chemical reaction is reversed, what happens to the enthalpy of the reaction?

nataly862011 [7]

Answer: C. The sign of the enthalpy of the reaction reverses.

Explanation: Enthalpy of a reaction is the net heat absorbed or released during a chemical reaction.It is represented by $\Delta H$ . It is negative for exothermic reactions in which heat is released and is positive for endothermic reactions in which heat is absorbed.
