i think it might be C but idk

Answer 16

An example of a food chain would be A plant is a producer > an insect eats the plant > a mouse eats the insect > a bird eats the mouse.

Answer 17

so B????

Answer 18

Well I am pretty sure that C would be a best fit, a food chain is more just showing how they relate to each other with feeding, although within a food chain I believe there is something called the 'calorific flow'/energy flow which is the energy.

Answer 20

Which is an example of an external response to stimuli?


A.
a rabbit running from a predator that is chasing it


B.
getting water to drink to quench the body's thirst


C.
a rabbit sensing a predator is approaching


D.
the body recognizing it is constantly feeling thirsty

Answer 21

Which choices can we eliminate simply on they aren't external?

Answer 22

A stimulus is something that triggers a response. An example of external stimulus is a ball hitting your face. The ball triggers a response in your body, causing you to react. An example of internal stimulus is hormone. Hormones such as testosterone triggers a response in various parts of your body internally.
External: When pea plants feel a solid object, they twist and bend to support themselves around it. Easier way of saying: thirst and hunger are internal and something hitting you is external.

Answer 23

Exactly what he's getting at, with that we can eliminate B and D

Answer 24

Oh wait

Answer 25

Just re-read the question, it states which of the following is an external RESPONSE to a stimuli

Answer 26
