HKDSE Biology Question Review (2021-01-24)

1. Why is transvestite an eunuch?

Solution:

The question implies that it is impossible for a woman to be a man because this implies real male genital needs to be transplanted which is beyond the capacity of modern medicine.

Transvestite is still biologically a male because there exists Y chromosome in EVERY NUCLEUS of his cells.

Injection of estrogen to promote breast growth implies adrenaline dissipation and thus reduction of lifespan.

The skeletal structure of a transvestite remains unchanged, so he will always look bigger than a real woman, especially the fingers and the face.

2. In a fiction, there was a technology called genetic defragmentation technology that can reset the physiological composition of an organism.

Assume that a male wanted to be a real female by such a technology, what is missing?

Solution:

A male has an Y chromosome from his father and an X chromosome from his mother. The Y chromosome needs to be replaced by an X chromosome.

Such a X chromosome must come from his father, not his mother. If both X chromosomes come from his mother, then he will suffer from gene degradation due to duplicated chromosomes from the same person.

An otaku has a recessive X chromosome from his mother, so he needs a dominant X chromosome from OTHER THAN his mother such that he can reproduce another otaku. This implies that he will be an MK because all females are MK.

男人想變成女人，最直接的方法就係刷首抽。然而根據世界人口比例，你有20%機會投胎做印度人日日飲恆河屎水同埋不分男女任人姦。

性別認同障礙同時表示一個人唔成熟。兩條基佬玩屎忽或者假閪(人妖即基佬)，呢啲係所有畜牲都識，係相當幼稚的動物本能。

宅男唔會接受任何形式的性取向。

我係連登識好多cross-dresser ，而反串唔係個個人都玩得起。

我係老牛聲，而且成身都係毛，無得扮女人。

有啲男人天生就係青龍無鬚無恥毛，加埋聲線夠高樣夠童顏，呢啲先係高級偽娘。

有男人想脫毛豐胸走去食雌激素做藥娘。

He is fucking himself.

佢係度捉蟲入屎眼。

體內男女荷爾蒙失調會加速全身器官衰竭。

做藥娘肯定死得早。

3. What is meant by logistic growth?

Solution:

It is exactly the law of diminishing marginal return. If a single input (e.g. metabolism) keep on adding up, the absolute return will be eventually a concave curve that drops to zero sharp some day.

4. Why plain Janes hate math?

Solution:

佢地食指長過無名指

而且數學勁的女人往往會被其他女人批鬥至死
