for bacteria it is reproduction, photosynthesis makes absolutely no sense, ur asking about the question which how bacteria forms groups right?

Assalam-o-alaikum wr wb...
bacteria were collected where there is more oxygen..the question was why were they arranged in those places...'those places' were chloroplast or something...so more oxygen is given out providing more concentration of O2 for bacteria to live in

 

[Ahmed Khider]

but it is saying they form groups, it starts with one bacteria and reproduce to form alot of groups, why will they form groups to respire?

Dude dont u get it..the question said they want to respire or something..im not making it up!!!If it was reproduction why the hell would they mention respiration????

it didnt say these places, it just says how they form groups, i think

No, not that way..
they said they live in areas of high oxygen which is a product of respiration; if you notice you will find that the bacteria accumulate near the chloroplast.

i dont remember the question, but did it say they are aerobic bacteria?

nope...it says these places!

 

[Abu mota]

nope...it says these places!

ok

It didnt say anything about them being aerobic or not..

 

[Skynox]

Since they require oxygen then thay are aerobic and they were near to chloroplasts…

Thats sooo right

 

[kareem1997]

oxygen is a product of photosynthesis... respiration uses oxygen to produce CO2 and water :S............... so the answer for whats the process that attracts the bacteria is photosynthesis :/

Guys what about the question of osmosis and the substances which are recycled??

Guys what about the question of osmosis and the substances which are recycled??

Carbon and water
Osmosis needs cytoplasm and cell membrane

 

[Ahmed Khider]

Carbon and water
Osmosis needs cytoplasm and cell membrane

Are you sure??Thx anyway

It's genetic only !!! Environmental changes don't have effects on GENES !!! if some one became diseased due to environmental changes does that mean his child will be sick too !

 

[kareem1997]

guys i hv know idea wat ru arguing bout.... dats it da exams over.. u wnt be able 2 change anythin... so just chill nd prepare 4 2mrws exam

The inheritance question is it both or genes only !! Needs someone to be sure. i think it's both but i did it genes only, need someone to tell me

Assalam-o-alaikum wr wb...
the question was in co ordinated science...you may check the mark scheme of it to be sure, your answer is correct anyway
take the link from the following post

Assalam-o-alaikum wr wb..
check this paper...question number 11
