DSE 生物BIOLOGY 區

長知識了

想問下Q11點解

因為y axis係intake rate but not substrste conc inside cells？所以個rate increase應該呈線性，而d幅圖前面個part個increase幅度細d，應該要y axis係 substrate conc inside cell先合理？

利申：唔知有冇講錯，唔肯定

可靠嘅mc答案係邊

樓主個個暫時算冇咩爭議
上面幅圖個個就算把啦
得啖笑

記左premolar1/2 molar2-3

A, C一定唔正確
因為佢話uptake by means of diffusion
所以個rate of uptake means net uptake
換句說話就係extra concentration must be larger than X to have net intake
而diffusion 就一直係linear increase of rate唔會係exponential increase

Premolar可以係兩隻
但cusp一定得兩個
幅圖唔止兩個

見到幅圖一定係molar啦
每邊兩隻加埋八隻

點解Q11唔係D嘅巴打
唔係好明

LONG Q 考左點乜????

mc得28/36
仲有無可能有雙星😭😭

4應該係D
Regeneration of RuBP唔會involve NADPH
所有RuBP都會directly拎晒嚟做glucose ，唔會有regeneration

Not a reason 喎
B 話carbon dioxide combine with 5C to form glucose directly 點都錯啦

哦 無嘢啦我眼殘

我上年錯6條先得星

錯2-3 條有冇雙星

我錯左呢條
同樓主個answer 比，total錯左3條

師兄犀利

但係上網搵premolar have at least two cusps wor, 我都揀咗0

有冇大神可以解答下：
Q11 點解係B唔係D? Concentration 越高 slope唔係越斜?
Q30 點解係D唔係C?
Q31 點解會係B?幅圖冇顯示if there is change in growth for males after age 20. 係咪應該係C?
Q35 點解係A唔係C
唔該晒

35 C嗰答案好搞笑喎點解你覺得會係C

會唔會出LongQ ans

我都覺得30係C，唔係D。D可以 compare 幾棵 plant 嘅 growth，但係題目淨係俾你一棵，所以我覺得 C好似合理一啲。
