The answer is b. is under purifying selection
If being short is the dominant trait, then you should expect the offspring to also be short.
This is because the traits are spread out as four different possibilities. Either FF, FF, Ff, or Ff. If the dominant trait is being short, “F” then this would mask the recessive trait “f”.
Answer:
1) Every planet's orbit is an ellipse with the sun at a focus.
2) A line joining the sun and a planet sweeps out equal areas in equal time(s)
3) The square of a planet's orbital period is proportional to the cube of semi major axis of it's orbit
Very powerful microscopes were needed before cells could be observed in detail
The right answer is Filtration.
A water filter is composed of a filtration system that aims to separate the water from the solid particles (residues) by passing it through a porous medium, which allows only the liquids and the finer solid particles to pass through. as the filter holes (porosity). The water that comes out of this filtration system is rid of solid particles larger than the pores of the filter.
Some water filters are designed to make drinking water (very fine filtration, less than the size of a microbe).
