Answer:

spontaneous generation

Explanation:

Spontaneous generation is the myth that organisms could originate without the need to have descent from similar organisms (i.e., created spontaneously from the dust). This belief stated that organisms could arise from nonliving material. Louis Pasteur conducted experiments in order to show that this belief was false and thus confirm the theory of biogenesis, which states living organisms can be only generated by the reproduction of similar living organisms. Pasteur showed that microorganisms could not be developed in isolated sterilized tubes, but they could be developed in open tubes, thereby showing that reproduction (biogenesis) is the only source of living organisms.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
AleksAgata [21]

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.
