Answer:
molds and casts
Explanation:
A nucleotide contains a base (adenine, thymine, guanine, or cytosine), sugar, and phosphoric acid.
Nucleotides are organic compounds that are composed of a base (one of the following four chemicals: adenine, thymine, guanine, and cytosine), in addition to a sugar molecule and a phosphoric acid molecule. They perform the function of monomeric units inside the nucleic acid polymers, which include ribonucleic acid and deoxyribonucleic acid. These two types of biomolecules are required for the survival of all kinds of life on Earth.
Nucleotides are required in order for metabolic processes and physiological functions to be carried out.

Answer:
A nitrogenous base, phosphate group and a deoxyribose sugar
A group of species that have a similar characteristic is called a family. Therefore, the correct statement is option C.
Biological classification is the science of organizing living organisms on their evolutionary relationships. Taxonomy allows scientists to provide a systematic way of naming and classifying organisms. Within each kingdom, organisms are classified into specific categories. The basic unit of classification is the species, which involves a group of organisms that have a ability to produce a viable offspring.
Above the species level, organisms are grouped into genus, families, orders, classes, phyla, and kingdoms. These taxonomic ranks are arranged in a hierarchical manner. For example, a family encompasses several genera, and a genus encompasses several species.
Families are groups of similar genera. It typically includes several genera of closely related species. A family is a taxonomic rank that comes above the genus and below the order, therefore, it constitutes several genus with closely related species.
Therefore, family is a group of species that have a similar characteristics.
