You investigate the effect of different concentrations of ethylene spray on ripening in bananas.
What would be the independent variable of this investigation?
(1 point)
the length of ripening time
the color of the bananas
the concentrations of ethylene spray
the age of the bananas
Which statement is true?(1 point)
In stems, auxin accumulation will occur on the side that is away from the light source, and cell elongation will occur on the opposite side.
In stems, auxin accumulation and cell elongation will occur on the side that is away from the light source.
In stems, auxin accumulation will occur on the side that is near the light source, and cell elongation will occur on the opposite side.
In stems, auxin accumulation and cell elongation will occur on the side that is near the light source.
Kid who hates Fortnite was wrong about the stem question, here is the full quick check test.
1: reproduction without another parent.
2: can help a species better adapt to environmental changes.
3: haploid gametophyte
4: the concentrations of ethylene spray
5: In stems, auxin accumulation and cell elongation will occur on the side that is away from the light source.
1: the concentrations of ethylene spray
2: In stems, auxin accumulation and cell elongation will occur on the side that is away from the light source.
thank you gamer
The independent variable of this investigation would be the concentrations of ethylene spray.
The statement that is true is: "In stems, auxin accumulation will occur on the side that is away from the light source, and cell elongation will occur on the opposite side."
To determine the independent variable in the investigation, we need to identify the factor that is manipulated or controlled by the researcher.
In this case, the independent variable would be the different concentrations of ethylene spray. The researcher would most likely apply varying concentrations of ethylene spray to different batches of bananas to observe and measure the effect on ripening.
For the second statement, the correct option is:
"In stems, auxin accumulation will occur on the side that is away from the light source, and cell elongation will occur on the opposite side."
This statement reflects the phenomenon known as phototropism, which is the plant's response to light. Auxin is a hormone that promotes cell elongation, and in response to light, it accumulates on the side of the stem that is away from the light source. This leads to cell elongation on the opposite side, causing the stem to bend towards the light.
