Explain why is it important to keep the airways clear?

Asmall number of finches are removed randomly from the wild and placed in a protected bird area. they are given as much food as they need and have plenty of space. why would natural selection not occur in this population? a. there is no reason for genetic mutation to occur. b. the birds compete for limited resources, c. the population has not reached carrying capacity. d. there is no genetic variation in the finches.

All phases of matter may have a fixed mass

The hardy-weinberg principle is that genetic frequencies in a population? will remain stable from generation to generation will always be changing will not be affected by environmental changes are always in a 3: 1 ratio
