Sarah described the following situation:

when fertilizer was added to one plant and nothing was added to another plant, there was a noticeable difference in the color of the leaves of the plants.

which of the following best describes the situation?

this is an example of correlation but not causation.

this is an example of causation but not correlation.

this is an example of both correlation and causation.

this is an example of neither correlation nor causation.

This is an example of causation but not correlation best describes the situation.

Causation is the capability of one variable to produce an effect on another. This is also known as cause and effect. There is a causal relationship between the two variables. The effect of the fertilizer (variable) on the plant which brings about a noticeable difference in the color of the leaves of the plants is causation. Correlation only describes the extent to which two variables is likely to decrease or increase in parallel.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest

human-caused climate hope this
