I believe the answer is Yy. Although Y represents the dominant trait for yellow, it being paired with the recessive trait, y, has the chance of a plant with green seeds to be produced in the next generation.
If the sediments are put down, it's deposition
If the sediments are being moved, it's erosion
Materials eliciting increased tongue flicking and prey attack in garter snakes were isolated from both earthworm and fish prey. New extraction methods based on chloroform-methanol mixtures are valuable adjuncts to the more typical aqueous preparations. Both high- and low-molecular weight components from earthworms and fish were active. The similarity between the active chemicals in these two classes of prey was established using several methods of analysis.
A heterogeneous mixture is a mixture of substances. In this mixture, substances are not chemically bonded just mixed, they're only together.
Examples:
A bowl of different nuts - Many types of nuts together.
A puddle of mud - Water, sand, leaves
Dirt - a bunch of particles held together.
