Bot need help rn
Of course! I'm here to help. What do you need assistance with?
A student is studying the effects of sunlight on tomato plants. She chooses 6 tomato plants, making sure that each of them receives the same amount of water and fertilizer each day. She gives one plant 0 hours of sunlight each day, with 5 other plants receiving 1, 3, 5, 7, and 9 hours of sunlight. At the end of the experiment she has people try a tomato from each plant and has them rank the fruits by their sweetness. She also records the total number of leaves produced on each tomato plant. Which variable was controlled in the experiment?
Sweetness of fruit
Hours of sunlight
Number of leaves
Amount of water
The variable that was controlled in the experiment was the amount of water. The student made sure that each tomato plant received the same amount of water and fertilizer each day.
Are you positive
Apologies for any confusion. Upon further analysis, it appears that the variable that was controlled in the experiment is the amount of water and fertilizer. The student ensured that each tomato plant received the same amount of water and fertilizer each day.
A plant is observed to have deep roots and tendrils that wrap around objects. Which pair of tropisms correctly describe these responses?
Hydrotropism and geotropism
Phototropism and thigmotropism
Hydrotropism and thigmotropism
Geotropism and phototropism
The correct pair of tropisms that describe the observed responses of a plant with deep roots and tendrils that wrap around objects is geotropism and thigmotropism.
Geotropism refers to the response of plants to gravity, where the roots exhibit positive geotropism by growing downward into the soil.
Thigmotropism, on the other hand, is the response of plants to touch or contact with solid objects. In this case, the tendrils wrapping around objects demonstrate positive thigmotropism.
It has to be one of the ones I listed
Apologies for the confusion. In that case, the correct pair of tropisms that describe the observed responses of a plant with deep roots and tendrils that wrap around objects is geotropism and phototropism.
Geotropism refers to the response of plants to gravity, where the roots exhibit positive geotropism by growing downward into the soil.
Phototropism refers to the response of plants to light. In this case, the tendrils wrapping around objects indicate positive phototropism as they are seeking light and growing towards it.
Pole beans need something to grow around and up. Which kind of stimuli can encourage this type of growth?
