In contrast, the mutated proteins prevent them from moving through the cell, this causes mucus to accumulate in the skin, in the lungs and the pancreas, a medical condition called cystic fibrosis.
tandem repeat is a microsatellite with repeat units that are 2 to 7 base pairs in length, with the number of repeats varying among individuals, making STRs effective for human identification purposes

I believe this would be false. Chaparral biomes can have many different types of terrains. The land in a chaparral biome can be mountainous, rocky, or flat. Chaparral biomes are generally defined by their temperature and climate. They are very hot and dry, and have mild winters and extreme summers. Hope this helps.
The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.
