Sucrose cannot pass the cell membrane, but water molecules can.

By the given percentages, we can conclude that the animal cell has a higher water potential, because it has a lower sucrose concentration. Meanwhile the solution has a lower water potential, since it has a higher sucrose concentration.

In this way, water molecules will move from the cell to the solution, due to osmosis.

Osmosis is always the water molecules, moving from a region of higher water potential to a region of lower water potential, through a semi permeable membrane, which is the cell membrane.

So what would happen is that the cell will shrink, because it lose so much water.

The law of conservation of mass states that matter can/cannot be created
anyanavicka [17]

Answer:

Cannot

Explanation:

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

The domestication and breeding of animals to have as pets, livestock on farms, or for work purposes is a form of artificial sele
musickatia [10]

Answer: Natural Selection is the (natural) process in nature whereby organisms (plants, animals, etc.) that are better adapted to survive and thrive in their environment, are more likely to survive in order to breed/reproduce and pass on their own genes and characteristics. These characteristics can be physical or behavioral.

Artificial selection is where man, instead of nature, determines which characteristics they would like to hone. In the case of crops, edible, tasty, easy to cultivate crops were chosen above harder to grow crops. Animals kept for meat and other products, were selected based on how much milk, wool, meat, etc. could be produced. Health was also a factor, as sickly animals are troublesome (and potentially unsafe to utilize their products). In the case of domesticated pets, let us consider the dog, originating from domesticated wolves. The more easily trained, protective, better natured wolves were chosen to continue to line of species and the undesirables discarded.
