Answer:
I think the answer would be D,I'm not really sure though,hope I'm right,sorry if I,m not :)
Explanation:
Answer:
The correct answer is "negative".
Explanation:
At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids. Since the peptide would have a positive net charge, it would migrate to the negative terminal of the gel because opposite charges attract each other.
The two groups differ in the composition of the cell wall and the lipids in the cell membrane. 3. ... Organelles contribute to efficiency in eukaryotic cells because they concentrate the biochemicals needed for chemical reactions so that the reactions proceed more rapidly.
I believe it is D, the reason being is because they form on their own, not from a living or dead organism. It can't be B because that is true, and the same for C. hope this helps, have an amazing day :)
Because water is polar and oil is nonpolar, their molecules are not attracted to each other. The molecules of a polar solvent like water are attracted to other polar molecules, such as those of sugar. ... Ionic compounds, such as sodium chloride, are also highly soluble in water.
