Answer:

c) bromthymol blue

Explanation:

An acidic solution has a pH value less than 7, while the pH is 7 for a neutral solution and grater than 7 for a basic solution.

Bromothymol blue is a pH indicator which is yellow in color when placed in an acid (pH under 7), the color is green in a neutral solution (pH of 7) and blue in an basic solution (pH over 7).

If bromthymol blue is added to a solution with an initial pH of 5.5 (acidic), the color would be yellow and as the pH changes to 8 (basic), the color changes to blue.

How can i make babies
Studentka2010 [4]

Answer with Explanation:

Babies are formed when the sperm cell from the male testicular gonad meets with the women's egg cell (from the ovaries). This penetration causes the<em> "fertilization process." </em>This naturally occurs two weeks from the woman's last day of menstruation. The fertilization allows the egg to rapidly divide. This is followed by "implantation," a process whereby the blastocyte attaches to the woman's endometrium. <u>Around three weeks, the blastocyte is formed into an embryo. </u>This will be called fetus once the woman reaches its 8th week of pregnancy.

This is a brief process regarding your question on how babies are formed.
