T's harder to find one of the many genes involved in a polygenic trait vs. the only gene involved in a discrete trait."
<span>It is probably not very difficult to find ONE OF THE GENES involved in a polygenic trait (as this answer suggests), but it IS difficult to find ALL OF THE GENES involved in the trait. </span>
<span>This sounds like a high school Biology or first year university question - chances are they're testing your reading comprehension as much as your scientific knowledge.</span>
The answer is the second choice (B)
EXPLANATION:
In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The animation at right shows a one-dimensional longitudinal plane wave propagating down a tube. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion. The wave is seen as the motion of the compressed region (ie, it is a pressure wave), which moves from left to right.
The second animation at right shows the difference between the oscillatory motion of individual particles and the propagation of the wave through the medium. The animation also identifies the regions of compression and rarefaction.
The units of density are g/ml. If you find the grams of 1 mol of ethanol (with the molecular weight), you can then divide by the density to get the ml of ethanol.
g*(ml/g)=ml
