A1 The agar jelly contains nutrients for the micro- organisms to use. Can you suggest what the word 'nutrients' means?

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

explanation:

the sun shines white and black light to our planet. the white light has all the colors in it. in our upper atmosphere, we have dust particles and oxygen molecules. the white light meaning all of the colors in a rainbow shines through the upper levels of the atmopshere and the blue light scatters across the entire planet. that is why our sky is blue.
