Which particle has a high rate of deposition?

Rom4ik [11]

Answer:

A particle with jagged, rough ends has a high rate of deposition.

Explanation:

When erosion takes place, the particles of rocks move from one place to another and then they get settled on the new place. Those particles which have round shaped ends cannot settle quickly because they can be easily pushed by air and again moved but particles having rough ends get stuck in the soil or surface of earth and they are settled quickly.

When testing to determine the presence of lipids in food, which solution or reagent should be used?

ArbitrLikvidat [17]

The answer should be C, Sudan red solution.

Sudan red solution dissolves in lipids, which can show a color of orange/red if lipid is present.

On the other hand, Biuret solution/reagent is used to test for proteins, and it'll show a color or purple if protein is present.

Iodine solution is used to test for the presence of starch, and it'll show a blue black color if starch is present.

And lastly, Benedict's solution is used to test for reducing sugars, and it'll show a brick red color (or green as small amounts) if reducing sugars are present after heating under boiling water bath.
