Re: I want quick help

The steel rods or bars in concrete resemble cellulose fibrils of plant cell walls whereas the cement represents pectin and (I guess) hemicellulose.

Organisms with a defined, heritable body plan. That's perfect for ruling out prokaryotes and it is indeed met by all eukaryotes. Great definition!

Well, yeah but with "blue" blood valencialiew meant deoxygenated blood. That's the convention.

Blue blood = deoxygenated or oxygen deficient blood.
Red blood = oxygenated or oxygen rich blood.

More blue blood means less oxygen supply to the body.

Re: Multicellular prokaryote

I'm glad that the misconception is over. Jorge and Chris both of you are welcome. I wonder why prokaryotes are still thought to be only single-celled, at least according to most textbooks, when in fact, Nostoc are multicellular prokaryotes. That statement of yours above is one of the the reasons I i...

Re: Multicellular prokaryote

No, Chris you are misunderstanding Jorge. He never said that you are complicating this. He said that the functional differentiation of cells in association with other cells of the same species is the FACT that is COMPLICATING the generalized concept that prokaryotes are unicellular. Complicating the...

Biohazard, thanks a lot for the comprehensive explanation.

Also, sweating is a physiological response found only in humans right? Because I have never come across another mammals that sweats.

Thermal insulation by adipose tissue

Well, adipose tissue is known to act as a thermal insulator.

1) Why do body organs need thermal insulation?

2) How does adipose tissue provide it? Is it a property of fat stores or something?

Thanks!

bacterial ETC

If the bacterial electron transport chain is located in the plasma membrane and the proton gradient is from outside the cell (high conc.) to inside (low conc.), then if bacteria are cultured in a medium slightly more acidic than normal, their rate of growth should increase. Am I right? Since, they'l...
