In an experiment, a researcher tries to cook an egg with sound. The researcher uses sound that can be heard by humans, and the temperature of the egg does not change. The researcher then uses an ultrasound device that creates much higher
frequency sound
waves, and the egg changes in
temperature from 21°C to 65°C.
Which statement explains the reason for the temperature change in the egg?
Neither low frequency nor high frequency sound waves have enough energy to vibrate the matter in the egg and cause it to heat
Both low frequency and high frequency sound waves have enough energy to vibrate the matter in the egg and cause it to heat.
Low frequency sound waves have enough energy to vibrate the matter in the egg and cause it to heat, while high frequency sound waves do not have the energy to heat the
egg
Low frequency sound waves do not have enough energy to vibrate the matter in the egg and cause it to heat, while high frequency sound waves do have the energy to heat the
egg

Dominance the dominant allele doesn’t fully mask or hide the recessive. for example, a red carnation with a white carnation will produce a carnation. one gene one trait. well most of the time than one gene controls a trait. we are all different but genetically speaking we are % similar with regards to genetic makeup.

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.

To determine if a particular plant is homozygous or heterozygous, you would have to test cross with a
