Answer:
The used up all their resources too fast and weren't able to regrow them in time; they eventually basically killed each other off.
Explanation:
A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
Answer:
The correct answer is - Protect organs
Explanation:
The skeletal system is the internal frame of the body that includes all the bones and joints present in the body. There are 206 bones in the adult human skeletal system.
The major roles of the skeletal system to help in movement, support, and protecting vital organs such as hearts, stomach, lungs, brain, and other organs. It also helps in movement and providing support to the body.
