When a plant grows toward or away from a stimulus, it’s called a tropism.

harina [27]

Explanation:

Phototropism- a response to light stimulus that directs the stem to grow toward the light and roots to grow away from it.

ii. Gravitropism- Stems and leaves grow away from the force of gravity while roots grow toward it.

iii.Thigmotropism - growth in response to touch stimulus. The side of the stem in contact with the object grows slower than the side not in contact. This causes the vine to twist around the object.

Describe how sandstone, a sedimentary rock, may become a metamorphic rock. Enter your answer in the space provided. HELP 30 POIN

pshichka [43]

Explanation:

When sandstone is overlaid by layers and layers of sediment, it becomes subject to enormous pressure and temperature beneath the layers and its grain structure begins to change. The force of compactness causes grain structure and size to reform. This is called metamophism., The sandstone becomes a new rock called quartzite. The two rocks will have different properties. Quartzite will have larger crystals and will be hard and smooth while sandstone will be coarse and soft.

Five dialysis bags constructed of membrane, which is permeable to water and impermeable to sucrose, were filled with various con

Gekata [30.6K]

Answer:

The options

A. A

B. B

C. C

D. E

The CORRECT ANSWER IS D.

Explanation:

It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.

If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.

At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.

The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
