  • Which Rat Had The Fastest Basal Metabolic Rate Bmr

    Basal Metabolic Rate has been defined as the minimum amount of energy needed by an animal to maintain the basic functions of survival (such as breathing). Several factors including age, gender, weight, and exercise affect the BMR. "BMR increases with increasing muscle tissue" therefore, exercising will enhance BMR while with increasing age, BMR is reduced (Scott, 2008). Also gender differences exist between males and females; it has been shown that males have higher BMRs than females...

    Resting metabolic rate can vary with age independently from body mass changes in the Colorado potato beetle, Leptinotarsa decemlineata. Abstract A study was done by Saija Pironine, leena Lindstrom, and Anne Lyytinen in the Journal of Insect Physiology, to investigate the age dependence of resting metabolic rate in Colorado potato beetle (Leptinotarsadecemlineata) from adult emergence until age 10 days. In their hypothesis they expected to see a bell shaped pattern in metabolic rate with adult age...

  • The Difference between BMR and RMR

    BMR (basal metabolic rate) Basal metabolic rate (BMR), and the closely related resting metabolic rate (RMR), is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive, which requires about twelve hours of fasting in humans). The release of energy in this state is sufficient only for the functioning of the vital organs, the heart, lungs and kidneys and the rest of the nervous system, intestine,...

Webb suggested that everyday sleep is similar to hibernation - sleep conserves energy at times when it’s harder to get resources (i.e at night time).

  • Temperature on Rate of Pnpp Hydrolysis

    LABORATORY 3 The Effect of Temperature on the Rate of PNPP Hydrolysis Partners: Shelby Cruickshanks Alexis Williamson Introduction Most of the chemical reactions, which occur throughout our bodies, would proceed at a much slower rate of reaction without the presence of an enzyme. Cells can not wait for centuries for molecules to break down, if they waited for that, there would be no way for the organism to obtain energy or in turn survive. This is where biological catalyst comes into...

  • Social Transfer Of Food Preference In Rats

    Transfer of Food Preference in Rats after Initial Taste Preference ---------- --------------- Abstract Rats are animals known to be neophobic, fearful of new experiences and tend to show behaviors of avoidance to eat novel foods. However, there are high chances that rats will eat novel foods if they have reasons to expect that the food is safe to consume and not harmful.
