How salt dissolves in water
lana66690 [7]

Answer:

Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon
stellarik [79]

Answer:

  1. Glycine
  2. Ribulose 1,5-bisphosphate
  3. 3-phosphoglycerate
  4. Glyceraldehyde 3-phosphate.
  5. Glucose
  6. Sucrose

Explanation:

The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.  

<u>Calvin cycle</u>

During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.  

During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.

During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.

<u>Cytosol: </u>

Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.

Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.

_______________ refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesio
dybincka [34]

Answer:

<u>Liquefaction</u> refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesion and mechanically fail to provide support during earthquake shaking.

Explanation:

Liquefaction occurs when an unbound material (usually sand), which is saturated in water, loses its resistance to shear due to intense and rapid vibration (earthquake), which breaks its granular structure by reducing its inter-granular pressure and flow like a liquid because of an increase in pressure.

Liquefaction usually manifests itself in loose, saturated and non-cohesive soils, formed by young deposits of sands and sediments of similar particle sizes. If the soil is dense there will be less chances of liquefaction. Older deposits, in general, are more dense and cohesive. At higher density, more interstitial pressure is needed for liquefaction to occur.
