Answer:
Probably because they just need air to being able to live and have air going in and out like carbon dioxide and getting rid of used air.
The sense organs contain receptors that are sensitive to stimuli.
The nervous system consists of the central nervous system - brain and spinal cord -and peripheral nerves. Nerve impulses travel through the axons of neurones - nerve cells. Reflex actions are fast, automatic and protective responses.
Human vision is binocular, which gives us a good perception of depth. Vision defects include short-sightedness, long-sightedness and colour blindness.
Eversion, a foot movement where the bottom of the foot is turned laterally (away from midline), is performed by the tibialis posterior muscle, assisted by the fibularis longus and fibularis brevis.
In the context of the question, eversion is a foot movement involving the intertarsal joints of the foot in which the bottom of the foot is turned laterally, away from the midline. This action is performed mainly by the tibialis posterior muscle. Other muscles that assist in this movement are the fibularis longus and the fibularis brevis.
The tibialis posterior muscle works to plantar flex (bend the foot downwards) and invert the foot (turn the sole of the foot inwards). In contrast, during eversion, the bottom of the foot turns outward, away from the midline of the body.
Understanding these movements and the muscles involved can help you visualize how our bodies stabilize while walking or running on uneven surfaces, make quick side-to-side direction changes in active sports, and more.

Answer:
Vital capacity can be defined as the maximum volume of air a person can breathe in after a forced expiration. It is equivalent to the sum of expiratory reserve volume (ERV), tidal volume (TV) and inspiratory reserve volume (IRV).
Now, the vital capacity of John would be = 450 + 2600 + 900 ml
= 3950 ml or 3.95 L.
B) the relative age of the rock
C) the absolute age of the rock
D) the level of radioactive isotope decay in the rock-
-At first I thought it was the date the rock was formed...But I think it wrong, so I looked over the text and now I'm thinking they want it to answer eider B-C relative or Absolute age of the rock. So I can cross off A and D. And by doing that, I had to take a look into my notes, and I notice my notes aren't the best but from what I know, Absolute determines whether it gives up the true ‘age’ of a rock or fossil. And Relative doesn't provide a “true age’’... But now that I'm thinking on it absolute looks to see if it mainly organic or tissue, while Relative mainly sedimentary rocks. So I'm thinking it B now, but I feel like I'm confusing myself with all this. So I wanted to understand this better and get a clear answer to this. If my answer wrong, can I get a short explanation as to why?-
