Its estimated that during sprint events approximately 95% of energy production comes via the anaerobic system (85% phosphate, 10% anaerobic glycolysis), and only 5% from aerobic oxygen. Thus, the 100m sprint is an anaerobic event relying heavily on energy supply from the ATP-PC system!
Answer: Membrane proteins act as receptors to molecules like hormones.
Explanation:
Membrane proteins are proteins that are closely associated with a cell membrane. On the cell membrane, they could act as receptors to molecules like hormones that need to be transported across the hydrophobic lipid bilayer.
A good example of membrane proteins is sodium channel, that acts as receptor to neurotransmitters.
In this case, brown frogs increase and green frogs decrease, whereas natural selection would cause this change in allele frequency.
<h3>What is natural selection?</h3>
Natural selection is the main evolutionary force by which populations change (evolve) across time.
Natural selection leads to the change in the allele frequencies depending on the more adapted phenotypes in a given environment.
In conclusion, brown frogs increase and green frogs decrease, whereas Natural selection would cause this change in allele frequency.

All cells have selectively permeable membranes, which means that only they let certain important molecules inside the cell, while the others stay outside the cell.
This occurs by the process of diffusion or osmosis.
