The balanced scale represents the equation: 2x + 1 = x + 5
If one x block is subtracted from the right side and one numbered block is subtracted from the left side. What process will balance the scale?

A. Subtract one x block from the left side and subtract one numbered block from the left side

B. Subtract one x block from the left side and subtract one numbered block from the right side

C. Subtract one x block from the right side and subtract one numbered block from the left side

D. Subtract one x block from the right side and subtract one numbered block from the right side

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
