I'm having trouble answering a question on my biology homework. Explain why the following structural formula is not correct base

I'd say that it is incorrect because each carbon atom should bond 4 times and all three carbon atoms in this structural formula only bond once. The reverse is true for hydrogen atoms. They only form one bond but in this structural formula two of them have four bonds. I don't know about nitrogen though.

Hoochie [10]

Answer:

The correct option is the number 2. Cystic fibrosis

Explanation:

Cystic fibrosis is a hereditary disease that affects the glands that produce mucus, sweat and digestive juices, this genetic disorder makes the secretions more sticky and thick, they accumulate and produces blockage in the tubes, ducts and passages, in particular in the lungs and pancreas.

The mucus block the ducts that carry digestive enzymes from the pancreas to the small intestine. Without these digestive enzymes, the intestines are not able to completely absorb nutrients in the food. The result is often, little increase in weight and growth, intestinal obstruction, particularly in newborns (ìleo meconium), among others.

Cystic fibrosis also affects the epithelial cells of the sweat glands, children suffering from this disorder may have a kind of salt layer on the skin. They can also lose abnormally high amounts of salt when they sweat on hot days.

Which of the following pairs accurately connects a macromolecule to its monomer?
Mice21 [21]

A monomer can be defined as the molecule that is capable of binding in long chains. The monomers bind together to form different polymers by the process of polymerization.

The monomer of carbohydrate is monosacchride. The monomer of proteins is amino acid, and that of lipids is glycerol and fatty acids. These three macromolecules are wrongly paired in the question.

The monomer of nucleic acids is nucleotide. This is correctly matched.

Hence, the correct answer is 'Option B - nucleic acids - nucleotides'.
