conditioning in rats. The purpose of the experiment was to condition rats to suppress certain hunger behaviors such as water licking. Burdick and James paired the neutral stimulus of white light with shock in a “test chamber” to see if rats would develop an association between the two stimuli. Naturally‚ shock induces a fear-like freezing behavior‚ and after being conditioned the rats displayed the same behavior but only to the white light. Furthermore‚ they would then place the rats back in their

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 Growth of Rats Problem Statement: When a ship sails across the ocean two rats are on board. A female and male are then left on a deserted island during late December. This island soon becomes the rats’ home. The number of offsprings that might be produced from this pair in a year should be estimated. One should make these assumptions when executing the problem. ❏ Every litter produces six young rats‚ and three of those six rats are females. ❏ The first rat that mates births six rats on January 1
