And clouds of white The bright blessed day
The dark sacred night
And I think to myself
What a wonderful world

Song by Louis Armstrong

Lyrics-

I see trees of green

Red roses too

I see them bloom

For me and you

And I think to myself

What a wonderful world

I see skies of blue

And clouds of white

The bright blessed day

The dark sacred night

And I think to myself

What a wonderful world

The colors of the rainbow

So pretty in the sky

Are also on the faces

Of people going by

I see friends shaking hands

Saying how do you do

They're really saying

I love you

I hear babies cry

I watch them grow

They'll learn much more

Than I'll ever know

And I think to myself

What a wonderful world

Yes, I think to myself

What a wonderful world

Ooh, yes

the krebs cycle and electron transport occur in the mitochondria, though other than that i would need to know more information.

i believe it is the first choice (1.)

and also as u said,( based on what buck learns within the call of the wild, "both the wild and civilization have rules".this is true of humans within society as well.
