Male widow birds can have short, medium, or long tails. However, females are attracted to widow bird with longer tails. The problem is that longer tails make it harder for the male widow bird to fly and avoid predators. A group of explorers capture a group of widow birds and relocate them to another island. This island also has many resources but has many predators. Which graph below represents the expected allele frequencies of the widow birds tails after several decades? Explain your answer.

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.
