How do sound waves move in air? a) the wave particles diffract around a barrier. b) the wave particles move in a curvilinear motion. c) the wave particles move via acceleration; that is, they increase speed. eliminate d) the wave particles displace one another, with particles replacing each other.

D, because the air s moving as in longitudinal waves which means a wave vibrating in the direction of propagation, and probation means that the making of more and replacing

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
