Answer the following question given this paragraph: Prokaryotic organisms reproduce asexually by binary fission , a process that produces identical offspring ( Figure below ). In asexual reproduction , a single parent produces genetically identical offspring. As prokaryotes do not have a nucleus, and have only one circular chromosome, they do not need to reproduce by the same mechanism as eukaryotic cells; mitosis does not exist in prokaryotic cells . Prokaryotic cell division is a much simpler process. In prokaryotic cell division, after the single chromosome is copied, the cell grows larger. Eventually the two chromosomes separate and move to opposite ends of the cell. Newly formed cell membrane then grows into the center of the cell, separating the two chromosomes, and forming two genetically identical daughter cells. Some eukaryotic organelles, such as mitochondria and chloroplasts, also divide by binary fission. Q: How do prokaryotic organisms reproduce asexually? A:
OPTIONS:
- mitosis
- residual fission
- kinetic fission
- binary fission
binary fission

Question: Answer the following question given this paragraph: The body does not exist in isolation. There is a constant input of water and electrolytes into the system. While osmoregulation is achieved across membranes within the body, excess electrolytes and wastes are transported to the kidneys and excreted, helping to maintain osmotic balance.

Q: Answer the following question given this paragraph: Visit this site (http://openstaxcollege. org/l/fermentation2) to see anaerobic cellular respiration in action. Other fermentation methods occur in bacteria. Many prokaryotes are facultatively anaerobic. This means that they can switch between aerobic respiration and fermentation, depending on the availability of oxygen. Certain prokaryotes, like Clostridia bacteria, are obligate anaerobes. Obligate anaerobes live and grow in the absence of molecular oxygen. Oxygen is a poison to these microorganisms and kills them upon exposure. It should be noted that all forms of fermentation, except lactic acid fermentation, produce gas. The production of particular types of gas is used as an indicator of the fermentation of specific carbohydrates, which plays a role in the laboratory identification of the bacteria. The various methods of fermentation are used by different organisms to ensure an adequate supply of NAD+ for the sixth step in glycolysis. Without these pathways, that step would not occur, and no ATP would be harvested from the breakdown of glucose. Q: Obligate anaerobes live and grow in the absence of what? A:
Answer:
molecular oxygen
