Therefore, a normal sperm cell will contain 22 autosomal chromosomes and either an X or a Y chromosome, but not both. E: All living organisms on Earth utilize the same triplet genetic code in which a three-nucleotide sequence called a codon provides information corresponding to a particular amino acid to be added to a protein. In contrast, many organisms, especially certain types of bacteria, do not use oxygen. These organisms live in oxygen-poor environments and may produce energy through fermentation. Other organisms may live in dark environments, such as in caves or deep underground.

Many organisms reproduce asexually by budding or self-fertilization, and only the most evolutionarily advanced organisms make use of neurotransmitters in their nervous systems. B: Sexual reproduction allows the genetic information from two parents to mix. Recombination events between the two parental copies of individual genes may occur, creating new genes. The production of new genes and of new gene combinations leads to an increase in diversity within the population, which is an advantage in terms of adapting to changes in the environment. The system of naming species is called binomial nomenclature. The first name is the genus, and the second name is the species. In binomial nomenclature, species is the most specific designation. This system enables the same name to be used globally so that scientists can communicate with one another. Genus and species are just two of the categories in biological classification, otherwise known as taxonomy.
BIO101: Introduction to Molecular and Cellular Biology
The levels of classification, from most general to most specific, are kingdom, phylum, class, order, family, genus, and species. As shown, binomial nomenclature includes only the two most specific categories. D: Fission is the process of a bacterial cell splitting into two new cells. Fission is a form of asexual reproduction in which an organism divides into two components; each of these two parts will develop into a distinct organism. The two cells, known as daughter cells, are identical. Mitosis, on the other hand, is the part of eukaryotic cell division in which the cell nucleus divides. In meiosis, the homologous chromosomes in a diploid cell separate, reducing the number of chromosomes in each cell by half. In replication, a cell creates duplicate copies of DNA.

Learning about the structures of cells, allows us to see the similarities and differences among organisms. Bacteria, plant, animal, and fungus cells are similar in many ways and contain many of ztudy same small structures known as organelles. However, some characteristics help distinguish whether a cell belongs to an animal, plant, fungus, or bacteria. For example, all plant cells contain cell walls, while animal cells lack this particular extracellular structure. The water within a cell that presses against the cell wall gives a plant its rigidity and your celery its crunch! Completing this unit should take you approximately 10 hours.
