R唔係叫 restriction enzyme咩

Becoz it have restriction enzyme PQR

Or QRS
Don't rmb since I have the paper dumped

The bacteria causes inhibitory effect on growth of plants is it parasitism ？

The bacteria causes inhibitory effect on growth of plants is it parasitism ？

Yes

有冇最終答案

個條問size of native plant 應該點答

個條問size of native plant 應該點答

Decrease abundance
Since Y Plant outcompete native plant in hk for food sources eg light
Al marking

Bio邊有老師敢出
佢地考都未必5**

個條問size of native plant 應該點答

我寫the size of native plants decreases as more bacterium available to promote plant growth so more soil nutrients are absorbed by foerign species because foerign species is more competitive than native species. Less nutrients for native species to support the growth so size decreases

類似啦
要講到前因：bacteria <> plant Y (promotion)
-> more plant Y
-> since given Y is more competitive
-> outcompete
-> blah blah blah

同樣道理
唔敢出

mc 第二題係咪有tricky 位
超計係stomach 都會有amylase 從bolus流入?

有都變哂性啦
胃酸pH值太低

但係條題目係話找到喎 就算變左性都會有酶架應該

變性唔叫酶
只係蛋白

因為無左「特定三維結構」

q29係咪冇ans揀？因為突觸只有係軸突個邊先有 但x個到係樹突喎

無問題
邏輯黎

軸突 <> 樹突

即係呢個突觸「同時存在係」軸突未端同樹突前端

軸突 <> 樹突

即係呢個突觸「同時存在係」軸突未端同樹突前端

反而係定義問題
Hkeaa on99

突觸(synapse): 「神經源」之間，前突細胞膜至後突細胞膜之間，訊息傳遞既空間
-> 重點放係「神經源」

但我題目問motor neurone
-> it connects muscle or gland
-> so that we will call the AREA between motor neurone and muscle fibre/ gland as JUNCTION
-> neuromuscular junction or neuroglandar junction

明顯佢呢題用字都有問題

Since synapse =/= chemical synapse nor electrical synapse

But in this q, it states SYNAPSES...

咁q7 點解唔係c？ 佢話葉片 咁姐係薄壁細胞都會以硬脹度互相擠壓 令葉片挺直架喎 咁咪應該有支持作用囉

我錯左呢題... 唔識lol
因為上網搵唔到資料support plant leaf is supported by turgidity but only vascular veins

其實保護細胞算唔算薄壁細胞？

咁你q4揀左咩？ 我就揀左D 因為我覺得成個實驗都唔關人事 佢整水浴純粹想令溫度一致

係 d
