Which of the following is a direct observation?

A. Music may help plants grow

B. The plant is 22cm on day 23

C. two plants must have died from insects

D. The plants will likely grow 2cm per day

Explanation:

The answer would be B. The plant is 22cm on day 23

A direct observation is something that was observed by one or more of the human senses. This is something that was seen, heard, tasted, touched, and the like.

The plant is 22cm on day 23 is a direct observation because it was something that was seen and measured.

The others are not direct observations, those are hypotheses or predictions because it is not something that was seen. For A and D, it is something that has not happened so it is a prediction. For choice C, it is more of an assumption because the researcher did not witness that insects caused the plant to die.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

helicase, i think thats it
