When a candle burns, energy is released in the form of light and heat.
Candles are used to provide light because when they burn, the energy which is released takes the form of light. Similarly, because fire is involved in the process, heat is given off as well.
Answer:
cell membrane controls the transfer of materials inside and outside the cell.
Answer:
anther
Explanation:
The anther is responsible for producing cells by meiosis
1. it is a non spontaneous chemical reaction
2. change in gibs free energy (∆G) is positive ie., ∆G>0
3. entropy is included in any change in gibs free energy. ie, ∆G= ∆H-T.∆S
where,
∆G = change in gibs free energy
∆H= change in enthalpy
∆S= change in entropy
T= temperature in kelvin
4. in this reaction the total amount of energy is a loss, (ie., more energy is needed to start the reaction than the energy obtained from it)
5. total energy is a negative net result.
6. in metabolism endergonic process is anabolic, ie., energy is stored.
7. examples: protein synthesis, Na+/K+ pump (drives nerve conduction and muscle contraction).
