The answer is protein
Osmosis happens when the osmotic pressure of two container separated by semipermeable membrane is different. The osmotic pressure could be exert by polar solute because they will attract water molecule. Protein, glucose, and sodium chloride is the common molecule that could cause osmosis. But protein is the main substance that keep the osmotic pressure of the blood in the body.
The correct matches are:
1. Sea level (0 m) - 100%
2. Mid-level elevation (4,500 m) - 57%
3. Peak (8,850 m) - 33%
The level of oxygen in the atmosphere depends a lot on the elevation. The smaller the elevation, the higher the oxygen level, and vice versa, the higher the elevation, the lower the oxygen level. So we have a situation in which the oxygen level is the highest at 0 elevation, or rather at sea level. As we go to higher elevations, let say to around 4,500 m, the oxygen level is significantly dropped, which makes it difficult for breathing. If we go even on higher elevation, like 8,850 m, than the oxygen level will much lower, and a human will need to undergo intense long training and also carry oxygen with him/her in order to survive.
Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.

Explanation:
Each unit of inheritance can have alternate states (alleles) that segregate at meiosis, with each gamete receiving only one allele (the principle of segregation, Mendel's first law); different alleles assort independently in the gametes (the principle of independent assortment, Mendel's second law).
