Better in convo!
One big reason for less people giving AS.......NO ONE ( no teachers) is supportive!
All energy made in the ecosystem comes from photosynthesis. The energy that the plant lost, kept, used, etc. ALL originally came from its photosynthesis. Therefore:
nice tyAll energy made in the ecosystem comes from photosynthesis. The energy that the plant lost, kept, used, etc. ALL originally came from its photosynthesis. Therefore:
Energy from photosynthesis: 27,000 + 3000 = 30,000
Energy from Sun = 1,000,000
Percentage = 30,000/1,000,000*100%=3%
I'm not sure, but for the airways to be constricted, smooth muscles have to contract. So they're more active. Also, activity of cilia should be less I think, because they become paralysed when one smokes I think due to mucus. I'm not sure why goblet cells would wanna do endocytosis, my guess is that they need to take in more materials now than before in order to be able to produce mucus. So I'd go for C but again I'm not sure.
i go for B as during asthma attacks more mucus is produced cuz some foriegn substance actually entered which triggered the asthma attack so choice 2 is now eliminated as exocytosis will increase not endocytosis and as 2 is eliminated the ans should be B the cilia will be more active as it will try to remove the excess mucus produced
is the answer C?
Your reasoning is good I change my mind loli go for B as during asthma attacks more mucus is produced cuz some foriegn substance actually entered which triggered the asthma attack so choice 2 is now eliminated as exocytosis will increase not endocytosis and as 2 is eliminated the ans should be B the cilia will be more active as it will try to remove the excess mucus produced
what is the answer by the way

i am doomed....Answer is B (checked the markscheme) and salma_69 is right exocytosis will increase nt endo
heyyy its okay we all make mistakesi am doomed....
going somewhere good i hopeLola_sweet Hows ur prep?
im nt mary jonesNO YOU AREN'T!
When she wants to she can Mary Jones !
Thanks for the encouragement..heyyy its okay we all make mistakes
