DOUBLE-CHECK PLS Study the picture below. State which tropism each area of the plant is responding to.
For the upper half of the plant pic the choices are:
A. Hydrotropism
B. Phototropism
C. gravitropism
Then for the lower half of the plant the options are the same but I have to only pick two, one for the upper part and one for the lower part only answer if you know.
My answers are:
(Upper part) *phototropism*
(And for the lower part) *gravitropism*

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
