How is Earth's surface most likely to change as rainwater flows downward over a rock formation over time? (3 points) Minerals will be left behind causing colored streaks.
Large sediments will collect on the surface of the rock.
The rock will become red due to oxidation from the running water.

Explanation:

The rainwater will act as a withering agent when flowing downwards over a rock surface. This will result as a disturbance in rock formation. ... The flowing rainwater can create pores, spaces or cracks in rock and erode away soil particles and sediments from it. Therefore,rainwater can create a jaggedsurface on the rock.

minerals will be left behind causing of colored streaks

Explanation:

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

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.
