Transpiration: process in which plants release water vapor into the air
Evaporation: process in which water changes to a vapor
Precipitation: water that falls from clouds toward the ground
Condensation: water vapor that cools down to form water droplets
Groundwater: flowing of rainwater downhill to form streams and rivers
The right answer is E.
Uracil is a nitrogenous base (pyrimidine) specific for RNA. The nucleoide of uracil is called uridine and nucleotide is called uridine monophosphate or uridylate. In the DNA, there is thymine instead of uracil.
So if we mark the uracils, only the RNA will be marked. The DNA will not be given that there is no uracil in it.
When prey is abundant, predator populations increase because more young are able to survive. More predators kill more prey, which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other.
The answer is A. When a potent drug is discovered, it has to undergo animal and human trials to test it ADMET (Absorption, Distribution Metabolism, Excretion, and Toxicity) properties. Using tissue cultures to test drugs, such as cancer drugs, prevents the incidence of subjecting humans to the unknown adverse effects of the drugs before the drugs are determined to be safe for use.
