Answer:

Reverse Osmosis.

Explanation:

This is the mechanisms of water purification for drinking water which is droven by the chenical potential of the solvent .

It involves the use of partiaiy permeable membrane to allow ions , water molecules ,solvent molecules to pass through during purification

A pertial permiable menenrane in this prurifiction process is the membrane that allow only water molecules, ions and restricted other unwanted chemical contaminants from passing through it.

Leno4ka [110]

Answer:

Positive feedback is used to build more contractions.

Explanation:

Positive feedback mechanism in humans is also observed during childbirth which is induced by the pressing of the ovarian wall by the baby.

The pressing sensation is passed to the brain via different nerves, and in response, the brain stimulates the pituitary to produce oxytocin.

Oxytocin is responsible for the contractions of the uterine muscles which cause the movement of the fetus towards the cervix, further increasing the stimulus.  

The positive feedback loop continues until the baby is born.

Softa [21]

Answer:

The animal cell will take in water until it eventually swells or burst

Explanation:

Osmosis is an important phenomenon that drives the movement of water across membranes. It is defined as the movement of water molecules from a region of high water concentration/low solute concentration to a region of low water concentration/high solute concentration across a semi-permeable membrane.

In this case, the animal cell with a molar concentration of 2.0M is placed in 0.0M and 1.0M sucrose solutions. This means that the cell is placed in an hypotonic solution (solution with low solute concentration), hence, water will move from the extracellular solution into the animal cell since the solute concentration in the cell is more. The animal cell will begin to swell and eventually burst.
