Answer:

presence of sugar means that the outside of the fruits is less dilute (more concentrated in sugar than water) than the inside of the fruits

in osmosis (diffusion of water molecules), water molecules have a net movement from a more dilute substance to a less dilute substance

sugar is the less dilute substance, so water is drawn out of the fruits and mixes with the sugar around them

the sugar dissolves in water, creating a sugar solution

this results in fruits with less water inside them, and surrounded by sugar solution

Why do you think toxicology is an important area of study in veterinary science?

Answers

Toxicology is very important because the substances that are not harmful to humans can be very harmful to animals. For example, dogs cannot eat chocolate but humans can. Toxicology helps determine the “poisons” that animals ingest and the medicines needed to remedy them.

Because some compounds that are not dangerous to humans can be exceedingly harmful to animals, toxicology is crucial in veterinary science.

What is veterinary science?

Veterinary science is defined as concerned with preventing the spread of animal diseases to humans as well as the prevention, control, diagnosis, and treatment of diseases impacting the health of domestic and wild animals.

Toxicology is defined as a branch of study that aids in our comprehension of the negative consequences that drugs, events, or chemicals may have on humans, animals, and the environment. The Threshold of Toxicological Concern (TTC) is a notion that refers to the determination of a level of exposure for all chemicals beyond which there would be no appreciable danger to human health, whether or not there are chemical-specific toxicity data.

Thus, because some compounds that are not dangerous to humans can be exceedingly harmful to animals, toxicology is crucial in veterinary science.
