Which of the following observations would support the claim that a particular mutation is neutral? a
The frequency of the mutation in a population, once it first appears, tends to increase over time.
b
In a given population, individuals that possess this mutation have a greater rate of reproduction.
c
The mutation is higher in populations of organisms that produce fewer offspring and have shorter life spans.
d
The frequency of the mutation goes up and down with no observable effect on the health of a population.

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.
