Answer and Explanation:
An acid has a pH that is less than 7. A base has a pH that is greater than 7. Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.
Situation 1: Base
Situation 2: Acid
Situation 3: Acid
Situation 4: Base
Situation 5: Acid
Situation 6: Base
A. Water directly out of the tap has a pH of 7.2. When you add carbon dioxide (blow into the water), you get a pH of 5.1. This means that the addition of carbon dioxide makes water more acidic.
B. The most basic solution will have the highest pH. This means that it will be water with bleach added to it.
C. The most acidic solution will have the lowest pH. This means that it will be water with instant coffee.
C. there is an equal amount of day and night everywhere on earth.

Since no table is given, I will explain how genes are inherited. After Mendel’s discoveries were
accepted, scientists realized that traits passed to offspring were the result
of genes being passed from parents to offspring. This is an example of the law
of inheritance. The genes that are passed down from the parents are being
shared by the offspring. It can be shown if the trait is recessive or dominant
from the parents’ gene. <span>Chromosomes
are inherited from the parents. One chromosome from each of 23 pairs came from
each of the parents. The two chromosomes of a pair (except for the sex
chromosomes) contain the same genes, but the genes have small differences. The
X and Y Chromosomes determine the organism’s sex. One chromosome pair - the sex
chromosomes - is unique. Typically females have two X chromosomes and males
have an X and a Y. Mothers always pass an X chromosome on to their children.
Whether the father passes on his X chromosome (leading to a pair of X
chromosomes) or his Y chromosome (making a mixed set) determines your sex. </span>
