A.) neutral

I can answer number 3. Osmosis is a unique property of water that allows water to move past cell walls. Like when water evaporates out of your plastic cup.
Diffusion (which is a kind of passive transport)
The structure (shape and number) of an animal’s teeth vary according to what food they consume.
For example, molars- flat teeth at the back of the mouth are very different among different types of animals:
• Herbivores (eat plants) have strong and flat molars ,
• Carnivores (eat meat) have limited number of molars,
• Omnivores (eat combine food) have molars for grinding.
On the other hand canine teeth are small or sometimes don’t even exist in herbivores are very defined and sharp in carnivores.
