Answer:
Oxygen
Explanation:
Oxygen (65%) and hydrogen (10%) are predominantly found in water, which makes up about 60 percent of the body by weight.
Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.
The sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
<h3>What is diffusion?</h3>
Diffusion is the process by which substances move from region of high concentration to regions of low concentration.
Based on the chart, sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
This is because the ions are at higher concentration in the pond water.
During the process, the ions move through ion channels in and out of the plant cell from the pond water.

Answer:
An example of survival of the fittest would be a sick moose versus a pack of wolves, the wolves are strong, fit and driven by hunger. The moose is sick and close to death, Clearly the wolves will win. Sadly I don't exactly understand evolution so I cant help with that part. Sorry.
