What are the advantages of Gram-positive bacteria? What are the main functions of bacteria? How is nitrogen metabolism in the prokaryotes vital to other organisms? Given the roles of bacteria in the nitrogen cycle, how would you answer people who consider all bacteria to be 'germs' and danger...
How does bacteria maintain homeostasis?Living Things:It's difficult to define exactly what life is. That's why scientists have a set of criteria to help determine what is alive and what is not. Living things must use energy, grow and reproduce, and maintain homeostasis....
Sciencealso shows that the gut plays a key role in regulating metabolism by influencing the absorption of, and interaction among, nutrients. Certain gut bacteria have been shown to produce metabolites, like short-chain fatty acids (SCFAs)—from complex carbohydrates and fiber that the human body ...
Barberry and goldenseal (Hydrastis canadensis) are often used for similar medicinal purposes becauseboth herbs contain the chemical berberine. Berberine has been shown to inhibit the growth of bacteria in test tubes, and may help the immune system function better. ...

in this area, influencing for example genomic stability or glucose metabolism (Han and Brunet2012; Kanfi et al.2012,2010). Furthermore, alteration in DNA methylation, chromatin remodeling and transcriptional alterations have been identified as targets for ageing research (Guevara-Aguirre et al.2011)...
Junk food is full of added sugars, unhealthy fats, and refined carbs. These foods don’t have the vitamins, minerals, or fiber our bodies need. This means they can cause weight gain and problems with metabolism, as our bodies can’t use these calories well. ...
Microbial colonization of the human intestine impacts host metabolism and immunity; however, exactly when colonization occurs is unclear. Although many studies have reported bacterial DNA in first-pass meconium samples, these samples are typically collected hours to days after birth. Here, we investigate...
How does carbon dioxide get into a plant cell? Explain the basic needs of energy and carbon for an organism. Why is carbon called the backbone of life? Describe the role of carbon in biological systems. What role do bacteria play in the carbon cycle? Explain how matter (carbon) is cycled...
Why do some living organisms have to perform anaerobic respiration? How is ATP produced in an anaerobic respiration? What is anaerobic respiration? Why is it important? How is ATP made in anaerobic respiration? How do bacteria carry out aerobic respiration?
