You have worked on a gene for eternal youth for the past ten years and discovered it is not the needed expression of a gene at all but the presence of an ""old age"" gene that needs to be knocked out to get to the ""fountain of youth."" what would be the outcome if the procedure used to make the gene-targeted (knock-out) mouse for the foy (fountain of youth knock out mouse) was embryonic lethal? would this still be a useful model to study?

Give three examples of plant activities that are affected by circadian rhythms and natural fluctuations in the length of daylight?

How would you expect the mrna codons that code for the amino acids that make up hemoglobin to compare between humans

How do temperature and salinity affect deepwater currents? question 15 options: 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 changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
