Q5.

The answer is A. In thermodynamics, the first law of conservation states that energy can never be destroyed or created but can only be transformed from one form to another. Therefore part of the electric energy was converted to light energy while the other dissipated as heat. However, the summation of the energy of these tow outputs in joules remains the same as initial electric energy.

The answer is B. This is because the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they turn electromagnets that convert the mechanical energy into electrical energy

julia-pushkina [17]

Answer: Fewer harmful mutations are inherited by sexual reproduction than by asexual reproduction.

Explanation:

A germline mutation is the mutation in the germ cells (of the fully developed sperm and ovum) of the parents. When the affected parents undergoes with the sexual reproduction the mutations are passed from the parents to the offsprings.

Lapatulllka [165]

Answer:

Grass

Explanation:

Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses

grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors

This is because it is a living thing (performs photosynthesis and cellular respiration).

Biotic means living, all of the other choices are not living, and would therefore be abiotic factors
