Answer:

Option (4)

Explanation:

The thermosphere is the layer in the atmosphere that protects the earth as well as helps in carrying the radio signals used for communication purposes. It is the region that lies between the mesosphere (below) and the exosphere (above).

In this layer, the radio waves are used as a medium for communication. These radio waves carry the data or signals in the form of magnetic fields as well as the oscillating electric field, which are commonly considered as the electromagnetic field (EMF). These radio waves carrying information travels at a speed of light in the air, transmitting these waves in every direction.

Thus, the correct answer is option (4).

Natalka [10]

<span>The answer to the question is 0 percent. In order to have wrinkled seeds, the offspring must inherit two recessive alleles from the parents. From the cross of RRYY and RrYy, there is no way for the offspring to have wrinkled seeds as one of the parents doesn't have the recessive gene for it, the RRYY parent. Because of this there is 0 percent probability of having an offspring that has wrinkled seeds and yellow seed color.</span>
