Cross a trihybrid with purple flowers and yellow, round seeds (heterozygous for all traits) with a plant with purple flowers, yellow seed color and, wrinkled seeds (heterozygous for flower and seed color). What fraction of offspring from this cross are predicted to exhibit the recessive phenotypes for at least two of the three characters? You must show all of your work. Genotypes of parents, all Punnett boxes, possible genotypes that fulfill this condition, and your mathematical work.​

Mention true or false : a) cholera is marked by acute diarrhea and no urination. b)mosquitoes are the source of dysentery germs.

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.
