If I am not wrong, that protozoa can destroy our brain and will result in death

do you know about Naegleria fowleri ?

hey... do you know about anatomy position ?

when you see yourself in anatomy position, our superior extremity and our inferior extremity are different..

Our thumb in hand is facing outside and our thumb in foot is facing inside..

It's weird, isn't it ?

I'm not sure... Maybe you can use an example like people who do sports... They will sweating.. U can explain everything from that ex..
Not only 2 systems but it will connect all the systems for sure.

That's only a possibility

I see.. So. we just consume antioxidant like usual.. But, I wonder how much antioxidant we need just in a day?

from http://www.biology-online.org/articles/antioxidant_overload_may_underlie.html

it's said that antioxidant can lead the heart to failure. It is true or not ? what do you think ?

Deoxygenated ? Is it a condition where there is no oxygen anymore or a little oxygen left ?

Hm... I didn't read all of the posting.. But for me, I think blood has 2 colours.
1. Bright Red that contains fresh blod
2. Dark red that contains dirty blood.

But, I don't know it's true or not.

Maybe it's because long time ago, our earth was one continent. Maybe the tree had offsprings and they were separated by time and grow each other.

But I don't know that's true or not. Because I'm only a novice in biology

CAM? day and night respiration?
I think conifers use C4 type.

But I'm not too sure... Maybe they are C4

But.. I think that chromosomes are alive because they are parts of cell and cell itself alive

Lysogenic ?
I think they are : absorption, penetration, Clefage (The phase where the virus join up with the bacteria), and the last is the production of the virus using the replication phase of the bacteria.
