Question

fill in the blanks by choosing the correct option, to complete the concepts of tonicity of solutions. you are stranded on a lifeboat with nothing to drink but seawater. this is not a good idea because the seawater is hypertonic to your cells, your cells will lose water and crenate. you are dehydrated and have to be admitted to the hospital. the nurse starts an iv of isotonic saline. this is the normal solution for you cells. water intoxication occurs when you drink large amounts of plain water. when you consume such large quantities the environment surrounding your cells becomes hypotonic, your cells will gain water, and the cells will lyse. paramecium have a contractile vacuole. they must live in a hypotonic environment. jellyfish living in the gulf of mexico live in ocean water with a 3.5% saline concentration. the fluid concentration of the jellyfish is also 3.5%. the solutions in the ocean water and the jellyfish are hypotonic. salmon spend their adult lives in the ocean and return to freshwater to spawn. the salmon are adapted to the ocean water which is hypertonic to their cells and the freshwater which is hypotonic to their cells. plants contain a cell wall which prevents them from lysing in a hypotonic environment water is stored in the vacuole and the inflow of water increases the turgor pressure. a wilted plant has less turgor pressure and the cell will plasmolyze in the hypertonic environment. plants at the grocery store are frequently misted. the environment is hypotonic to the plant and the plant will take on water from the environment.

Explanation:

Tonicity refers to the relative concentration of solutes in two solutions separated by a semi - permeable membrane. Hypertonic solutions have a higher solute concentration than the cell, causing water to leave the cell. Hypotonic solutions have a lower solute concentration, leading to water entering the cell. Isotonic solutions have the same solute concentration as the cell. Plants have cell walls which protect them from bursting in hypotonic environments and plasmolyze in hypertonic ones.

Answer:

You are stranded on a lifeboat with nothing to drink but seawater. This is not a good idea because the seawater is hypertonic to your cells, your cells will lose water and crenate.
You are dehydrated and have to be admitted to the hospital. The nurse starts an IV of isotonic saline. This is the normal solution for your cells.
Water intoxication occurs when you drink large amounts of plain water. When you consume such large quantities the environment surrounding your cells becomes hypotonic, your cells will gain water, and the cells will lyse.
Paramecium have a contractile vacuole. They must live in a hypotonic environment.
Jellyfish living in the Gulf of Mexico live in ocean water with a 3.5% saline concentration. The fluid concentration of the jellyfish is also 3.5%. The solutions in the ocean water and the jellyfish are isotonic.
Salmon spend their adult lives in the ocean and return to freshwater to spawn. The salmon are adapted to the ocean water which is hypertonic to their cells and the freshwater which is hypotonic to their cells.
Plants contain a cell wall which prevents them from lysing in a hypotonic environment. Water is stored in the vacuole and the inflow of water increases the turgor pressure.
A wilted plant has less turgor pressure and the cell will plasmolyze in the hypertonic environment.
Plants at the grocery store are frequently misted. The environment is hypotonic to the plant and the plant will take on water from the environment.
