Hence she wrote for 2nd part:


The layer of oil acts as a barrier, preventing oxygen from entering the water, therefore, the guppy in setup B will die when the oxygen is depleted in the water.

My girl's answer has no 'lesser' but was marked 'right'. Ok..I think I know why..comparison. She has a second part which i thot unnecessary earlier on. That could be why she got it 'right'. It goes...

\"On the other hand, set up A allows oxygen entering into the water continuously. As a result, guppy in set up B is likely to die before guppy in setup A.\"

Lor-so.

See, your dd make a full story while my ds only half way through. :lol:
BTW, I like you dd's answer about the difference between two cycles. Very smart.

Wld someone pls enlighten me how can air enters into the stagnant water in setup A?

I was told I needed an air pump for our fish tank, else the oxygen in the water is not replenish and the fishes will die. Was I tricked by the shopowner?

I am always under the impression that fish will swim near the water surface to gasp for air when there is insufficient oxygen in the water (again told by someone). but knowing how fishes in water take in oxygen via their mouth n passing the water through their gills, how do the fishes then breathe near water surface?

Err strictly speaking, E3 is the one who started it first when she promoted Happy Mama to Ermei Zhan Men Ren. I only ask whether she looks like 周芷若 but then you have to suggest Botox for the older nun (which we all agree no way is Happy Mama going to be look like her, kekeke).

Nevertheless, I have to be honest and admit that *ahem* I'm too young to have the opportunity to watch shows of that era.

But... who is this 周芷若? and hallo..... why do I need botox when I have the skin of a 16-year old??

Oops! Just kidding lah! hahaha!!! :rotflmao: :rotflmao:

I think when they ask such question, they are looking for comparison..'lesser', 'hotter', 'shorter' are comparison. Or lor lor so so like mine to state how one differs from the other. I hope I am right.

Aiya...almost slipped my mind! We have teachers here! E3 & Happy Mama (& anymore...who else Science teacher?)...can advise?

Haha...my girl just asked me not to say she lor so. She said if only write the 1st sentence, it is only explaining \"why the guppy wil die\" not \"who die first\". :lol:

Wow, your dd got scientist potential leh. Seriously. 思路清晰，逻辑严谨。

Hmmm....I cannot answer you on the fish breathing on the surface stuff because I have absolutely no idea. On the O2/air into water, I rem, long long time ago, I ever read from a text before that air does enter into water w/o pump. But, the solubility of O2 is low in water. For an aquarium, I think pump is used to filter, and pump in more oxygen to supply the fishes. :lol:
