Is the activation of receptors in the various sense organs?
GaryK [48]

Answer;

-Sensation

Sensation is the activation of receptors in the various sense organs

Explanation;

-Sensation is the activation of sensory receptor cells at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern. Perception is dependent on sensation, but not all sensations are perceived.

-Receptors are the cells or structures that detect sensations. A receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes.

I need a poem about Photosynthesis and Cellular Respiration: has to have at least 20 lines and includes these words: ATP, Carbon
Neporo4naja [7]

Photosynthesis The Poem

I stand as a plant.

But what do I need?

I cannot make a sandwich

to feed.

But lucky for me

I have Photosynthesis, you see!

I take the Carbon Dioxide

And some water too

Altogether, I have Glucose for food

This gives me ATP energy

Which I need to survive

And so I do not come to my demise

But this also makes oxygen

Which I do not need

So I give it to humans so they can breathe.

Cellular Respiration is what they use

a little bit of oxygen

glucose tagging along too

they produce water and CO2

the mitochondria capture the energy

and use it

to power you so you can make tea!

My superpower may seem unreal

but it's not I promise

as crazy as it may feel.

My leaves grow big and strong

To reach out and soak up sunlight

that's far beyond.

I have organelles in my cells

that humans do not

They're called Chloroplasts just like you thought!

And they give me food like the chips you bought.

Chloroplasts take the suns light

And use it to make me food

like the glucose I eat every night!

Please don't laugh, I tried my hardest lol

Do whatever you'd like with it, take snippets of it or don't use it at all but either way I hope it helps a little!
