Answer:
The correct answer is A. Fossil fuels are cheaper than alternative forms of energy
Explanation:
Fossil fuels are made from organic matter of dead animals and mainly plants who were buried in the soil over hundred and thousand of years. We use fossil fuels because they are the best source to provide energy in the current time.
Fossil fuels are easily available and are present in very large amount which is the main reason for it to be cheaper. Fossil fuels like coal, petroleum or natural gas are more cheaper and efficient than alternative forms of energy like solar or wind energy.
But in future these fossil fuel will not be there and alternative forms of energy will become the primary and cheaper source of fuel.
Answer:
D)

If the explosion doesn't alter the Earth's rotation, the lack of moon would cause the Earth to rotate at a constant speed. This means that every day would be 24 hours long for the rest of the Earth's existence. The Earth's tides would also change because the gravity the moon exerts on the oceans would no longer exist.
Answer:
The test cross is shown below
T T
t Tt Tt
t Tt Tt
The alleles shown in the vertical side (tt) are recessive and come from the male parent. The alleles TT are dominant and come from the female parent.
For the variety of offsprings to be 100% tall, the recessive parent had to be crossed with a homozygous dominant parent. If the female was heterozygous with which the cross was done,then there would be small tomato plants in the offspring generation.
