Answer:
Nucleus
Explanation:
Humans are eukaryotic organisms. Their cells have a well-defined nucleus in which the genetic material is present in the form of chromosomes. Chromosomes have genes arranged in a linear manner. Genes represent the stretch of DNA that code for a specific protein. Being diploid organisms, humans have two complete sets of chromosomes. Therefore, each chromosome is present in pairs. These pairs are called homologous chromosomes. One chromosome of a pair comes from an egg cell and is called the maternal chromosome. The other chromosome is contributed by sperm and is called a paternal chromosome.

water filtration systems work by capturing undesirable elements in the water and allowing only clean water through. Water filtration systems for residential use that use actual filters, such as the thin film composite in reverse osmosis, do this by using microscopic pores that block even small bacteria while letting water through. Others work through other materials such as activated carbon or sand, which essentially scrubs the water clean.
