Answer 1

@k-nowhere

Answer 2

Alrighty

Answer 3

Here is the first question:

Which is an example of an internal stimulus?

a sudden change of air temperature
an artificial light that attracts insects
an increase in the amount of water available to a plant
a decrease in oxygen levels in the blood during exercise This one?

Answer 4

That's correct. I was going to say it could also be B, but I realized that that has nothing to do from within.

Answer 5

That decrease in oxygen (an internal event) tempts you to catch your breath.

Answer 6

Okay. Thank you. Here is the second question:


A dog may become frightened and cower when it hears loud thunder. This is an example of a reaction to what kind of stimuli?

chemicals
light
touch
sound This one?

Answer 7

Yuppers!

Answer 8

Okay. 3rd question:

What is one example of a response?

water lost from the lungs during breathing
ivy growing around the pole of a fence
the angle of the sun changing during the day
outside temperature dropping at night This one?

I am not to sure about this question, but this is just what I thought it might be. Feel free to tell me if I am wrong.

Answer 9

It would be the third option this time. I think of it as a sort of depend v.s. independent variable situation.

Water will always be lost as long as you breath no matter how fast or slow you breathe.
The suns angle will always change during the day, due to gravitation forces and such.
The temperature will always drop during the night, even if it's just slightly.
A plant will grow, *but* since theres a fence in its way, it has to grow *around* the fence.

Answer 10

What type of stimulus is an allergen such as pollen?




response to a stimulus This one?
external stimulus
internal stimulus
inborn stimulus
