The structure of this oligopeptide is attached:
It consists of arginine - alanine - phenylalanine and leucine
From the picture we can see that N terminus charge is +1
Also Arginine is considered as basic amino acid with charge +1
C terminus charge is -1
At pH = 8, the whose pKa are less than pH will be deprotonated and the net charge will be +1
So the net charge of this oligopeptide is +1 at pH = 8

Explanation:
A. The picture of the graph is attached. You can tell the amount of protons in an element by looking at the periodic table. The elements are ordered by the number of protons in an element.
B. Carbon and silicon are at the peaks of the chart. The peak is the highest point in a graph.
C. The elements belong to the non-metal group.
D. The halogens are non-metals, and their vapors are colorless.
The halogens are toxic to humans.
Halogen molecules are made of two atoms; they are diatomic.
Halogens react with non-metals to form crystalline compounds that are salts.
The halogens get less reactive going down the group on the periodic table.
Halogens can bleach vegetable dyes and kill bacteria.
E. The picture of the table is attached. To figure which numbers to put where, you need to pay attention to the other numbers. The halogens follow a trend with each of these properties. You have to put in the numbers that fit in among the other numbers.
