3. The figure above represents forelimbs from mammals that all have different uses depending on the
environment in which they live, yet they all have the
same basic pattern of bones. They inherited this
pattern from a common ancestor. This type of evidence
for evolution is called...
a. Analogous Structures
b. Homologous Structures
c. Vestigial Structures
d. DNA Sequence Comparison

a. to encourage apoptosis

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.
