Answer:
causing the thin filament to be pulled towards the center of the sarcomere.
Explanation:
<h3><u>Answer;</u></h3>
In order from the most likely to bind an oxygen to least likely;
3 bound o2, po2=100mmhg1 bound o2, po2=100mmhg3 bound o2, po2=40mmhg1 bound o2, po2=40mmhg
<h3><u>Explanation;</u></h3>
- Haemoglobin is more likely to bind oxygen if its other oxygen binding sites have already bound to an oxygen molecule.
- The higher the partial pressure of oxygen in the blood also makes it more likely that the hemoglobin will bind oxygen.
Chordates include many species, and humans are also chordates!
some adaptations that both humans (and other chordates) and plants needed to do to live on land were:
-protect the offspring from the environment (before the offspring could be just released into water) for example by covering seeds by shells
-evolve pores in the skin for gas and other substance exchange
-protection from drying up -a better outside layer, such as the skin!
Gravity. The force of gravity on a person or object at the surface of a planet is known as weight.
