Which of these statements is true about adaptive evolution:

A. Adaptive evolution is a permanent change in a trait.

B. Adaptive evolution is a temporary change in a trait.

C. Adaptive evolution is a fluctuating change in a trait.

Answer: C. Adaptive evolution is a fluctuating change in a trait.

As a result of our ever changing environment, adaptive evolution leads to a fluctuating change in traits. With evolution leading to changes in organic matter over time, adaptive evolution results from the body’s need to survive or adapt to certain changes in the environment. There is always a constant need to adapt and when evolutionary changes occur as a result of such adaptations, such changes are bound to fluctuate as the environment will most likely change again and the body will be left with the task of adapting to such change.

Math Calculus — AID—

Total time spent: 4 hours 15 minutes (it is equivalent to 255 minutes). Let the flight time from Paris to Glasgow be X. Then the flight time from Glasgow to Paris will be (X+10). We have an equation with one unknown variable: X + 45 + (X+10) = 255 ⇒ X = 100 So the […]

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]
