a. rate of expansion.

Explanation:

The various theories of the final destination of the universe depend on the current current of the universe, known as the rate of expansion.

We then use the term expansion rate which is related to the measure of how much the total space of the universe has increased over time. It is also necessary to clarify that relativity only restricts the speed at which bodies move through space, but it does not in any way restrict the rate at which space changes in size. One of the effects of the expansion of the Universe is to make us see the galaxies around us moving away from us. In addition, this distance speed is proportional to the distance between us and the observed astronomical object. This means that an object that is more distant moves away from us faster than another that is closer

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
