Answer:
An acid is a substance that donates hydrogen ions. Now there are more hydrogen ions than hydroxide ins in the solution. This kind of solution is acidc. A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions moves the other way.

Answer:
This disorder is caused by a recessive allele, its inheritance is sex-linked.
Explanation:
The disorder affects boys born to unaffected parents, this means that at least one of them has to be a carrier of the allele which causes the disease. So, if the allele was dominant, it would express in parents and sons. But, in this case, only is expressed in sons, so it can´t be dominant. Moreover, this condition has a sex-linked inheritance because it is always seen in boys and never in girls. This happens due to boys only have an X chromosome, so if they inherit the recessive allele of the disease, they will express it. On the other hand, girls have two X chromosomes, so if they inherit one copy of the recessive allele, they will be carriers and they won't be affected.
This disorder is never seen in females because they need to have two copies of the recessive allele. However, to have double copy, they should inherit one copy from their mothers and one copy of their fathers, but boys with the allele are affected and they die in early teens without having progeny. Therefore, a girl can't have a "carrier-father", so they will never have two copies to express the disorder.

Organic means it is made only of carbon.
Explanation:
The all four types of macromolecule are organic means these all four type of macromolecule made up of carbon. These four macro molecules are carbohydrate, protein, nucleic acid and Proteins. All are essential cell component perform a wide array of function.
Biological macromolecule is organic so they contain carbon. A part of carbon they contain nitrogen, hydrogen and additional minor element. Enzymes and some hormone are example of protein.
