C.There is less salt in fresh water. D.There is more and more salt in fresh water. 30.From the passage we can learn thatD. A.Marc conducts the experiment all by himself B.the vegetables have more salt than sugar C.carrots grow well,as was expected ...
Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top. The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down. 【小题1】In which step of the experiment ...
D.Fresh and sea water. 3.It can be known from the passage that. A.salinization brings great benefits to farmers in Holland B.the farmer did the experiment using high technology C.vegetables grew better in sea water than in fresh water in the experiment ...
Saline ice water irrigation must go through two processes:saline ice melting and melt-water infiltration,which determine the effect of irrigation together. An in-lab saline ice melting experiment was conducted using saline water,two in s... Y Zhang,J Yang,R Yao - 《Acta Pedologica Sinica》 被...
2.In Step 4 of the experiment, why do you pour the water over the spoon “slowly”? A. It is easier to see what you are doing. B. It pushes the fresh water to the bottom. C. It will keep the water from coming out. D. It will keep the liquids from mixing together. ...
A long term simulation test on salt-water dynamics in unsaturated soils with different groundwater depths and soil texture profiles under stable evaporation condition was conducted.Salinity sensors and tensiometers were used to monitor salt and water variation in soils.The experiment revealed that in ...
Experiment 1. Effect of water content at the surface of loins on salt uptake and water loss After the three days of storage previous to salting, the weight losses were significantly lower in the control loin pieces (C) (3.66 ± 1.87%) than in the surface-dried loin pieces (D) (8.40 ±...
