我好憎E2﹐我連core同plant/ecosystem有關的都答得唔好

定*

但有啲題目要答 reabsorptions of useful substances increase the water potential of glomerular filtrate ->much higher than blood->larger proportion of water is reabsorbed???
定我記錯

邊條?

印象中上堂做過 唔知係係pp 我記錯都唔知

定*

呢條？

17年個E2 狗也不屌

我直頭睇都唔睇就揀E4﹐有得背marking的E4 點都好過on99 的ecology
我連16, 17 的core 都未做(聽朝做)

諗住聽朝操份Ls再做

Andy tse話今年好大機會係VNTR
2013dse有出過vntr

果個term應該out syl
我溫果時係記coding region同non coding region有mutation影唔影響survival chance﹐因而影響variety的多少
所以先有DNA fingerprint的pattern

等我參考下先 但自己效率低 加油啊大家

其實VNTP係咪淨係識(iii)呢度嗰啲就夠？

第一句應該係"at least one", but not "one".
同埋字眼上要寫好啲先穩陣地有分。係inherit X-chromosome bearing the normal/defective allele, not "X-linked allele"。
其餘整體邏輯都通，可以係alternative answer

想問下大神們唔同experiment題目有啲咩assumption 同precautions要記
次次做題目都失左呢d分

最記得cross pollination個experiment一定要切走同一朵花個anther同埋用膠袋笠住成盤嘢

呢個差d都唔記得 多謝絲打提醒
好鬼煩 好似多數都係植物果d濕勁實驗先要make assumptions

我諗佢係想你suggest一個possible explanation. It is possible that the water loss is greater than the water uptake, leading to the guard cells becoming flaccid, and hence the closure of stomata。
你仲諗唔諗到其他可能性?

呢題應該al pp有考過
因為我呀sir份notes有而書好似無

唔係，可以連結去DNA fingerprinting，正如上面巴打所講

啱啱醒起如果要做唔同temp關於enzyme既food test
喺加enzyme之前要分別將個sample同enzyme擺喺特定溫度10分鐘 等佢地適應左個溫度先再mix埋佢地

搵翻學校呀sir份notes有寫你呢個答案
巴打op

可唔可以影份notes黎睇下
我都係google搵答案

大家加油

2016過來人 大家加油啊

我覺得唔會考 因為書無
