To control its wild rabbit population, the Australian government introduced the viral disease myxomatosis. At first the virus was very deadly to the rabbits, but over the years, the virus became less deadly. Explain what might have happened to the rabbit population and why the virus became less dead

Natural Selection

Explanation:

Overtime the the animals that had a natural immunity to the disease bred and produced offspring that also had this immunity, while the other animals that didn't dies off. So the population would have become smaller, but only for a little bit. Overtime this immunity will become more common in the population.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
