What are two ways that animals defend themselves

A pangolin will roll up into a ball-like shape to protect itself.

Tiger have sharp claws to fight-off and injure their enemies.

Hi there, two ways animals can defend themselves could be when a predator trying to make a baby animal their meal so the mom or the dad defends their young by biting their attacker like lions, tiger, ext..  Another way could be a kagaroos kick. When kangroos feel threatened, the need to defend themselves, they'll kick their attacker. I hope this helps :)

depends on your school

when i was in high school i took ap biology my senior year and it was the hardest one for me because my teacher finished the material within the first month of school and then went on to doing advanced college level it was horrible. but at a nearby school ap biology was one of the easier aps. also, it depends on what you are interested i like math a lot so ap calculus was easier for me than most but i hate history so ap us government was harder for me than most.
