You are studying leaf development in a member of the mustard family. You identify several mutants of interest in this plant and make pure (true-breeding) lines of each mutant for further study. You decide to conduct a genetic analysis of these mutant lines by crossing each with a pure wild-type line. The numbers in the F2 indicate the number of progeny in each phenotypic class. Three crosses between pure lines of flowers. The first cross is between twist and wild type flowers. F1 flowers have twisted leaves. When F1 flowers were crossed with each other, 53 twisted and 18 wild type flowers were obtained. The second cross is between forked and wild type flowers. The F1 generation is all forked, and when they are crossed with each other, 49 forked and 16 wild type flowers were obtained. The third cross is between pale and wild type flowers. The F1 generation was of middle coloring and when they were crossed with each other, 17 wild type, 16 pale, and 34 middle type flowers were obtained. From these results, determine the relationship between the mutant allele and its corresponding wild-type allele in each line.

The phlogiston theory in the 17th century attempted to explain burning. the theory stated that combustable objects contained a material called phlogiston, a substance without mass, color, odor, etc. after objects burned, the objects were dephlogistonated and were then in their true form. the phlogiston theory was accepted until the 18th century, when lavoisier proved that combustion requires a gas that has mass. phlogiston is considered a) to be scientific knowledge b) not to be scientific knowledge c) to be proven by scientific method d) to be accepted in the modern scientific community

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
