我都係9,10
其實10(b)天然選擇係唔識做既
我不斷重複part a d pt+吹下水

第8題(a)part幅圖都唔知乜來, 點做?

天然個度其實唔難，但難就難羅足分

都係講，佢只係殺左對劑冇抗性個d蚊，但有抗性既仲係度，一直少左只係少左冇抗性個d

一年一年咁過,有抗性個d 佔蚊既比例越來越大，一直咁繁殖
所以個殺蟲劇"看似"一年比一年失效，其實冇，只係殺左大部份對佢有效既蚊 <=當然呢句唔洗寫

但點解有D蚊會有抗性,你又點答?

胃潰瘍

我答:
假說是細菌引致胃潰瘍

第二條答(唔係我,係我個fd,因為我知我個個錯硬):
兩個陪養"名"
一個放幽門桿菌
一個放抗生素

之後唔記得左

首先，佢有冇問你呢個問題?

can tolerate the insecticide => survive and reproduce =>
hv resistance

有呀...問你之後殺蟲劑殺唔死佢地

你指最後個題??

if yes,我肯定你理解錯

下面有part 4分叫你解釋點解有變異
唔識

杰少仔

你呢個問題其實一早已經係唔知第一定第二條答左

問點解殺左d蚊
d蚊仲可以繁殖

我寫...搵d病人...一d俾胃藥佢地食...一d俾抗生素,一d 2樣都俾...

I said put the bacteria into 2 different petri dish
1 add antibiotics and 1 dun add...
then observe their growth

下面有part 4分叫你解釋點解有變異
唔識

1:染色体基因排列 隨機，是random唔同,有變異

2:唔同基因組合精子 + 唔同基因組合x子 已經可以組合好多不同合子


我係咁吹only

I think it is because of the chemical
what is the question asked about?

我吹水...

有d蚊中左dd殺蟲劑...唔足夠殺唔死佢...

之後身體產生抗體...再同第2d蚊交配...生下一代...

所以下一代既蚊有不同程度既抗殺蟲劑能力...遺傳變異

我淨係寫左第一點independent assortment of chromosomes

第二點空左, 但聽到人吹mutation(突變?)

點解唔同蚊有唔同程度既抗程
explain two reasons

杰少仔

同你地吹水好辛苦

要我出動呢樣野
