Hi, while I read your comments, I have the following questions. 

1. Ed 1. line 12 - you mentioned if  the algae adsorbs the metal or the metal adsorbs the algae, then I should consider re-phrasing as "and metal oxide nanoparticle interactions".

In this case, I'm not sure how to re-phase (how would you revise these sentences??). What I meant was "the algae adsorbs the metal or the metal adsorbs the algae"

2. Ed 2. line 14 -
What I meant was "nanoparticle impacts on algae". Do you think the edited sentence is clear? or do you have to revise the sentence, based on what I meant here?

3. Ed 8. line 122 -
What I meant was the algae themselves are transformed into toxic products by ROS. In this case, do I have to change the sentence in Line 122, based on what I meant?? , if yes. how would you make that change in this sentence??

Look forward to hearing from you soon.

Thanks.
