Answer: Option 4.
The fresh water is hypotonic and the salt solution is Hypertonic.
Explanation:
Hypotonic solution is a solution that have little dissolved solutes i.e low osmotic pressure compare to other solution. When a cell is put in hypotonic solution, it take in water and the cell swell up and it does not burst due to it's cell wall thereby becoming turgid or hard.
Hypertonic solution is the solution where the concentration of solute is higher outside the cell than inside the cell. Example is saline water.when a cell is placed in Hypertonic solution it will shrinks because it losses water.
Support the cell. Aid in cell movement.
Heterotrophs
Explanation:
Heterotrophs are organisms that depends on autrotrophs to transfer energy and their carbon compounds.
Heterotrophs are plants and animals that are not capable of producing their own food on their own. They depend on mostly plant materials and products for their own nourishment.
- Organisms that are able to produce their own food are called autotrophs.
- Autotrophs takes up raw materials from the environment and manufacture their own food.
- Autotrophs can be photosynthetic or chemosynthetic.
- Autrotrophs are producers in the food chain or web.
- Heterotrophs are consumers at all level. They depend on the materials produced by the autotrophs for their own survival and nourishment.

<span>Answer: continually increasing pressure on the unaffected lung.
In tension pneumothorax, the pressure is so high that it will push surrounding organ like another lung, heart, or blood vessels. Pushing another lung can make it less expandable, so less air can come inside and less oxygen can be gained.
Pushing heart and blood vessels can also disturb blood circulation.</span>
The answer to this question would be: Stomach(gaster), HCl
Protein digestion happens in the stomach. The stomach will secrete the acid which was HCl to kill bacteria inside food and denatures the protein. The acid also activates pepsin enzyme and in turn, will digest the protein into smaller amino acids.
