The correct statement about macromolecules is 'Proteins are made of amino acids'. It should be noted that in other options, the statements have a part reversed and therefore they are incorrect.
The correct statement about macromolecules is 'Proteins are made of amino acids'. Macromolecules are large, complex molecules that have a high molecular weight. They are mostly built from single subunits, or building blocks, called monomers. In this context, amino acids are the monomers that make up proteins which are a type of macromolecule.
To provide some clarity on the incorrect options: `Simple sugars are not made of polysaccharides` but the other way around. Polysaccharides are complex carbohydrates that are made up of simple sugar monomers. Similarly, `glycerol is not made of fatty acids`, rather, it combines with fatty acids to form lipids. Lastly, `nucleotides are not made of nucleic acids`, but nucleic acids are made of nucleotides. So, it's important to understand the relationships between these biochemistry terms to correctly understand the nature of macromolecules.

Answer:
PROTEINS!
Explanation:
Amino acids, often referred to as the building blocks of proteins, are compounds that play many critical roles in your body. They're needed for vital processes like the building of proteins and synthesis of hormones and neurotransmitters.
Answer:
Proteins
Explanation:
Amino acids are the monomers, or the building blocks of proteins. There are 20 different amino acids that can make up proteins. The ribosomes in a cell perform protein synthesis and create proteins by assembling the amino acids, according to the DNA's genetic code. The proteins created are used for structure, growth, repair, maintaining pH, balancing fluids and more. In addition, they can be used as enzymes and hormones.
The importance of the hydrogen bonds to the function of a DNA molecule as it holds the complementary strands and is responsible for its structure.
DNA has a double-helix structure. It has two antiparallel strands. Both strands have a sequence of nitrogenous bases that are linked together by hydrogen bonds.
The hydrogen bond holds together the base pairs in the middle. Adenine is always bound with thymine and guanine to cytosine in DNA by hydrogen bonds. In absence of hydrogen bonds, DNA would have to exist as a different structure, not a double helix.

Answer:
DNA has a double-helix structure because hydrogen bonds hold together the base pairs in the middle. Without hydrogen bonds, DNA would have to exist as a different structure. he major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.

Answer:
Bacteria with antibiotic resistance gene/s are favored by natural selection.
Explanation:
The presence of one or more antibiotic resistance genes in the bacteria becomes an adaptive trait in the presence of antibiotics in the surroundings. These bacteria have higher chances of survival and reproduce more to produce more progeny as compared to the bacteria that lack any antibiotic resistance gene. Therefore, the frequency of antibiotic-resistant genes in the population increases over the generations. Here, the increased fitness of bacteria having antibiotic resistance gene/s in the presence of antibiotics represents a natural selection.
