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

sessile, feeding on their host plant's 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?

Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Explanation:

A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.

The hypothesis can be tested by comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

What type of fault is formed when divergent plate move​
ValentinkaMS [17]
A divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.[1][2] Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill.

Plant shrinks when places in saltwater due to osmosis of?
aivan3 [116]
Water.

osmosis always refers to the diffusion of WATER down a concentration gradient.

diffusion can be applied to any substance;
osmosis only applies to the diffusion of water.

in the situation described, osmosis occurs by water diffusing out of the plant, down the diffusion gradient (because the salt water effectively has a lower concentration of water than in the plant) and into the salt water.

There are two different alleles for flower color, P and p. The image shows a white sweet pea that is labeled with its two allele
Triss [41]

B. White petal colour is a recessive trait.

Explanation:

In Mendelian genetics, the alleles depicted in small letters are recessive traits.

Since both alleles are same and in lower case they are homozygous recessive alleles for a white coloured petal gene.

The genotype of the trait will be tt because if it is crossed either with heterozygous or homozygous P alleles it will appear as tt to have phenotypic trait of white colour.

So the genotype will be tt.
