There is a carrying capacity for humans. This is because humans will eventually run out of Natural Resources and space.
Humans cry. Goldfish do not have the capability to do so.
yes
humans haven't even got the full capacity so the answer is no
Humans only use about 20% of the muscles capacity
No, crying actually decreases lung capacity because the baby is working so hard to tell you something is wrong that they're not breathing as much as they should be. See the related links for source material.
no
Humans need to maintain enough space and resources to increase the earth's capacity for all species. They have to make sure that they and other people have enough to survive.
Early humans were regulated by the carrying capacity of their ecosystem. More recently, however, the intellectual abilities of humans have allowed us to create our own niche, as well as increase the carrying capacity of the biosphere for our population.
oxygen carrying capacity is 1.34 ml of oxygen per gram of hemoglobin.... taking normal amount of Hb in humans as 15g/ dL , then oxygen carrying capacity for 100 ml of bood will be = 1.34*15 = 20 ml of oxygen approximately.
true
Yes - Neanderthals.
