Answer:
The incidence of mid-digital hair will not change because it offers no selective advantage or disadvantage.
Explanation:
The traits of an organism are determined by the genes of an organism.
In the given question, the trait is the hair growth on the middle digit or finger which is passed on to the generation but in some, it is expressed and in some, it is not.
This trait does not provide any benefit to the humans neither they are disadvantageous and thus is the neutral trait. Therefore, this trait will not change over time.
Thus, the selected option is correct.
Answer:
convention cells
Explanation:
In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.
