Whiteflies are common pest insects found on cotton, tomato, poinsettia, and many other plants. Nymphs are translucent and mostly

sessile, feeding on their host plants' phloem (sap) from the undersides of leaves. They undergo incomplete metamorphosis into winged adults. Because whitefly nymphs cannot escape predation by moving, you hypothesize that their translucent bodies make them hard to spot by predators. How could you directly test this hypothesis? _____ Select one: a. Compare rates of predation on whitefly nymphs on plant leaves of different colors (for example, red vs. green poinsettia leaves). b. Compare rates of predation on whitefly nymphs coated with a nontoxic dye vs. undyed whitefly nymphs. c. Compare rates of predation on whitefly nymphs vs. whitefly adults. d. Compare rates of predation on whitefly nymphs by predators that are translucent vs. predators that are not translucent. e. Compare rates of predation on whitefly nymphs feeding on poisonous plants vs. those feeding on nonpoisonous plants.

The hypothesis devised in this study by the researcher is –  

" White fly nymphs escape predation because of their translucent bodies."

In order to test this hypothesis, the researcher is required to conduct an experiment where two sets of white fly nymphs are formed and fed to their predators. The two set of subjects would be -  

Set I – White fly nymphs with translucent bodies  

Set II- White fly nymphs with translucent bodies coated with harmless dyes.  

The number of predated flies in each set can be compared to deduce justification for assumed hypothesis.  

Hence, option B is correct

Ecology: Resources

In this question, they are asking us to pick the information that favors the construction of a solar array over the hydroelectric dam and the coal-burning power plant.

Let's look at each statement:

A. The solar array requires more maintenance than the power plant or the dam.

In this case, the statement gives information against the solar array.

B. The coal-burning power plant and power line are less expensive to build than the solar array.

Here it says that the solar array is more expensive, so is also against it.

C. The overall price of a unit of electricity the solar array produces is lower than in the other solutions,

In this option, it says that it's cheaper to produce electricity using the solar array so is in favor of the solar array.

D. The energy from the solar panels is nonrenewable, while the energy from the dam and the coal plant is renewable.

Here it says that the energy from solar panels is nonrenewable, which is against the solar array, but also false because solar energy is considered renewable energy.
