The answer is Sugars, or sugar molecules!

Explanation:

The sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. Phloem is composed of living cells that transport a water solution of sugars that we commonly call sap.

Answer from: sabrinarasull1pe6s61

The molecule is Sugar ,transported principally as Sucrose, but originally as Glucose after photosynthesis and stored as starch in plants.

The sucrose is transported in the Phloem( one of the vascular tissues, the second is the xylem. They are located adjacent o each other.)The process of transportation is called, Pressure Flow Model. The process of moving the sugar through the plants is called Translocation.

There are two regions during transport of sugar in translocation. The source where the sugar is produced, that is the green leaves, and the sink where the sugar is metabolized.

Therefore the high concentration of the sugar at the source([plant leaves) increases the solute potential of the cell in the phloem of the leaves. This set up a gradients that draw water from the adjacent xylem into the phloem by osmosis.

The water influx increases the pressure potential of the phloem sap, and which makes the phloem turgid. The creates turgor pressure because of the increases of the phloem sap (containing sugar).The pressure leads to the bulk transport of the sap contain sugar (translocation) from the source( leaves) to the Sink.

At the sink, the sugar is withdraw . Thus the solute potential rises,(with a drop in pressure potential) and water return by osmosis back to the xylem for the process to continue with another transport.

Answer from: Quest

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.

It should be cryosphere and hydrosphere

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
