C. Useful energy out of a system is always less than the energy input of that system.

Explanation:

The correct statement of the given options is that useful energy out of a system is always less than the energy input of that system.

This is in compliance with the third law of thermodynamics which states that "energy transformation in a system is not 100% efficient".

  • At every stage energy is usually lost when it is transformed from one form to another.
  • There is no machine that is 100% efficient.
  • A machine that is 100% efficient will convert all the useful energy in it to do work and even more.
  • In system energy is usually lost as a result of heat and to overcome friction.
  • This reduces the amount of energy out of a system.

What will happen if the pollen tube pore its content inside the embryo sac?
anastassius [24]

Answer:

Once the embryo sac has developed, pollination has occurred, and the pollen tube has grown into the ovary to make contact with the ovule, fertilization (fusion of egg and sperm) can occur.Typically, the pollen tube reaches the embryo sac via the micropyle (Greek, mikros + pyle = small opening), or opening, in the integuments of the ovule.. There, it discharges its sperm into the embry

Explanation:

The pollen tube enters into the ovule, through the micropyle. Inside the embryo sac, the tip of the pollen tube ruptures and the 2 male gametes are set free near the egg apparatus. Inside the embryo sac, one of the 2 male gametes fuses with the egg nucleus and forms a diploid zygote. This process is called syngamy or true fertilisation.
