My lecturer gave me a mini-assignment on describing the possible characteristics of posthumans in the distant future. Here are my ideas:
1. Sexual dimorphism becomes more apparent, but their difference in social roles instead becomes less.
2. They get taller but less robust.
3. They are highly intelligent, typically able to solve complex mathemtical problems all in their minds subconsciously while they are doing something else like driving or cooking.
4. They become un-emotional in their reasoning. Vulcan-like.
5. They live in a community but prefer solitude whenever possible.
6. They converse with each other but prefer to be silent and engage in monologues whenever they can.
7. The gradual shift from fertility to survivability means that they live very long lives but have very little children.
8. Their sexual organs tend to be geared more for pleasure, not reproduction.
9. Capable of ESP, telekenesis, etc.

Is it plausible?I don't want to lose marks here. Please help me

I know glycolysis occurs in the cell membrane and may take place with or without oxygen it initially takes place in the cell membrane and continues into the cytoplasm. The result is the gain of two atp and the end product pyruvate.

The krebs cycle occurs in the mitochondria it produces the most enery

is this correct? I'm confused about:
What are the starting molecules of every cycle of respiration and the end products?
