DSE程度嘅話,應該係
不過事實上好複雜,within一個circuit for pupil construction,係可以involve cerebrum,不過應該唔洗識。呢個真係有錯請指出

pupil constriction係咪involve medulla, no cerebrum
重問

書裡面淨係講pupil reflex係controlled by medulla oblongata,所以應該outsyl
2018-04-01 23:22:53
大腦唔involved
個reflex control centre 係cranial nerve(dse無提到cranial nerve可以做control center)
2018-04-01 23:23:46
Independent assortment嘅意思係,一pair alleles嘅separation係唔受另一pair alleles嘅separation影響,書應該有圖去illustrate

homologous chromosome係咪都會以line up形式show under mitosis?
想知道係咪homologus chromosome can be observed under meiosis only or not
2018-04-01 23:29:03
你讀到neuroanatomy就知有兩個reflex係responsible for pupil constriction, 其中一個經visual center of cerebrum
DSE雞唔洗理會!!!照記cerebrum唔involve

冇錯係有chromosome line up。不過Mitosis好似唔用homologous呢個字,當啲chromosome line up。
當chromosome喺pair up at meiosis,咁就會寫埋homologous,強調兩個chromosomes屬於同一pair

當chromosome喺pair up and also line up at meiosis,咁就會寫埋homologous,強調兩個chromosomes屬於同一pair

即係同一pair chromosome係mitosis情況下唔會consider做homologus?
2018-04-01 23:46:14
我諗緊如果有條問題問is homologus chromosome shown only in meiosis
咁跟番你幅圖 起mitosis 紅色,藍色依兩pair會唔會consider做homologus
2018-04-01 23:50:06
首先你要搞清楚咩叫homologus chromosome
2018-04-01 23:53:10
我唔係咁嘅意思。
Homologous chromosomes by definition就係同一pair chromosome,任何情況都係咁。
但當你喺Mitosis用上homologous chromosomes line up呢個字眼,就會引來誤會,令人以為你係講chromosomes兩個兩個雙行排嘅情況,所以一般喺mitosis,都係就咁寫chromosomes,去表達所有chromosomes一個一個單行排。

Sorry,有小小更正。啱啱wiki,Homologous chromosomes除咗係指同一pair chromosomes之外,仲指已經pair up姐,所以mitosis應該直頭唔可以寫homologous。

thx

可唔可以以分享下樓主臨考前一日會做啲乜
2018-04-02 00:16:32
唔緊要,出卷尤其是MC應該會刻意避開呢個位,因為做咗咁多pastpaper都未遇過呢個困局,其實都只係大家定義不同。
不過,LQ安全起見,mitosis唔好寫homologous,唔寫一定啱。
2018-04-02 00:20:42
睇返啲pastpaper,唔會做,齋諗同望
2018-04-02 00:23:37
我都知道mitosis唔使寫homologus
只係想再清楚d concept
驚mc會出條比較做字眼既問題

啱啱再google 有人話算homologus
