Savage Garden - Santa Monica

In Santa Monica in the winter time
The lazy streets so undemanding
I walk into the crowd
In Santa Monica you get your coffee from
The coolest places on the promenade
Where people dress just so
Beauty so unavoidable
everywhere you turn
It's there
I sit and wonder what am I doing here?
But on the telephone line I am anyone
I am anything I want to be
I could be a supermodel or Norman Mailer
And you wouldn't know the difference
Or would you?
In Santa Monica, all the people got
modern names
Like Jake or Mandy
And modern bodies too
In Santa Monica, on the boulevard,
You'll have to dodge those in-line skaters
Or they'll knock you down
I never felt so lonely,
Never felt so out of place
I never wanted something more than this
But on the telephone line I am anyone
I am anything I want to be
I could be a supermodel or Norman Mailer
And you wouldn't know the difference
On the telephone line, I am any height
I am any age I want to be
I could be a caped crusader, or
space invader
And you would know the difference
Or would you?
Or would you?
on the telephone line I am anyone
I am anything I want to be
I could be a supermodel or Norman Mailer
And you wouldn't know the difference
On the telephone line, I am any height
I am any age I want to be
I could be a caped crusader, or
space invader
And you would know the difference
Or would you?

⑷ 细菌的芽孢和外毒素在细胞的什么时期形成

稳定期 由于培养基中营养物质消耗,有害代谢产物积聚,该期细菌繁殖速度渐减,死亡数逐渐增加,细菌形态,染色性和生理性状常有改变.一些细菌的芽胞,外毒素和抗生素等代谢产物大多在稳定期产生.有害代谢产物积累，新增细胞数目与死亡细胞数目达到动态平衡，次级代谢产物大量积
累，形成芽孢（稳定期的细菌种内斗争最激烈），繁殖速率逐渐下降。
