Red blood cells (a good, colorful example of an animal cell type) when placed in pure water swell up and eventually explode. Why
Snowcat [4.5K]

Answer:

When red blood cells are placed inside pure water they normally swell up and eventually explode. Red blood cells in pure water swell up because the pure water enter in the red blood cells by mean of osmosis. The water molecules are able to enter the red blood cells because the salt concentration inside the red blood cells is more than that of the pure water.

As water continue to move inside the cells, the cell swell up and eventually burst because the internal pressure inside the cell is greater than the external pressure, therefore the cell membrane become ruptured and eventually burst.

Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of kno
xenn [34]

Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is :  The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test <u>color, malleability, melting points</u>, and to test how shiny or dull it is. I would propose these to increase the <em>certainty</em> in the identity of the metals.  Btw, please mark me brainliest.

Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".

The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.
