5,3,4 岩呀...
你睇番個圖...
5唔經3  點跳去4...
唔係全部reflex都唔使association neurone嫁...

hormones方面  大部份係由protein組成
仲有d係其他野組成  e.g.  fat

好似話..只要有溫度既野都會有r ...

For pt 3, no...
air temp > body temp... radiation 係energy gain...大家都有放radiation,但四圍的環境更熱...總energy係gain左...
因此這裡radiation唔係散熱,但從convection ,conduction吸番,而係由頭到尾都係從果3樣吸熱

For pt 4...
of coz only the one on the right grow towards the left...mica plate係唔比auxin過...

Actually,the theories that sunlight decomposes auxin are not confirmed...so we cant say it is destroyed...but we can say that auxin move away from sunlight only...
and i dun think it is really destroyed...what if there is light from all direction...all auxins would be destroyed?[[tk_02]]

auxin果題兩條都會bend嫁...
我之前做pp..(好似係05..)
有做過一條咁既野...
做果陣已經覺得兩條都bend..
但係阿哥mark個ans係只有左邊bend(好似)
之後覺得怪怪地就上網check..
結果個ans係兩條都bend

no,there are 2 theories...just depends which one u follow...both can be ans
unfortunately,in CE lv,HKEAA follows the auxins move away form light theory[[tk_02]]
ur pt is valid,but if u say that to a CEer,u will kill him[[tk_02]]
