In some parts of the world, up to 20 percent of people perceive cilantro as tasting soapy.Curious, Miguel asks two more friends, Akeela and Domingo. Neither of them taste soap when they eat cilantro.For science class, Miguel decides to make a model of this chromosome that will show the difference among the four students taste of cilantro. Which statement below describes what the models should look like? A. All four model chromosomes should be identical. B. Only Miguel's model chromosome should be different. C. Only Domingo's model chromosome should be different. D. Only Lauren's model chromosome should be different.dont need an explanation :)

During photosynthesis, pigment molecules in chloroplasts must absorb eight photons (four by each photosystem) for every O2 molecule they produce, according to the equation 2H2O+NADP++8photons2NADPH+2H++O2 The standard freeenergy change ( ) for the lightindependent production of O2 is 400 kJ/mol. Assuming that these photons have a wavelength of 700 nm (red) and that the light absorption and use of light energy are 100% efficient, calculate the standard freeenergy change for the process.

It is estimated by a wide body of scientists that in recent decades we have begun another mass extinction event on Earth. Amphibians in particular have been in decline,sometimes due to climate change,and they therefore provide a possible early sign of dramatic biodiversity change to come. With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest,mutations of DNA sequences of the frog genome that are inherited by offspring A) could either be beneficial or harmful. B) will primarily be harmful. C) may have no effect at all,be beneficial,or be harmful. D) will only speed the decline and extinction of the species
