Answer:

A) Power plant

Explanation:

The key to understanding this question, is first knowing what "stationary" means. When something is stationary, it doesn't move, it just stays in one place.

Since power plants are buildings, they naturally don't move. On the other hand, the other choices are all vehicles that are intended to move. So while all of these options do cause air pollution, the power plant is the only one that is stationary.

I hope this answer helps you :)

What process involves the turning off or on the genetic information of a cell
JulijaS [17]

Differentiation is the process that involves the turning off or on the genetic information of a cell.

Differentiation is the process in which a young and immature cell changes into a specialized cell (a mature form with distinct function). Generic embryonic cells undergo differentiation to become specialized cells through the process of gene expression in which specific combination of genetic instructions are turned on (expressed) or off (repressed).
