I have attached the answer
remember that when the solution is acidic, pH lower than 7. there are extra H+ that the amino acid can take. the basic part of the amino acid takes this extra hydrogen (the nitrogen).
when the pH is higher than 7, basic, there are not much H+ available. the amino acid loses a H+. the acid part of the amino acid loses the H (the carboxylic part).

The answer is (2). To calculate the density, you need to divide the mass with volume. When doing division, the significant figures of result is the minimal of the numbers using before. So the answer is 2.
Not A because
2-Pentyne, an organic compound, is an internal alkyne. It is an isomer of 1-pentyne, a terminal alkyne
Is B because
DescriptionPentenes are alkenes with chemical formula C ₅H ₁₀. Each contains one double bond within its molecular structure.
