Metabolic rate refers to the “amount of oxygen consumed by the body cells” (Farlex‚ n.d.). it can be affected by numerous factors‚ some of which being the mass of the animal‚ its physical activity and temperature. Invertebrates are able to live in highly variable conditions due to their metabolism having evolved over time. Homeotherms are animals that are able to maintain a specific body temperature without relying on the temperature from its surroundings. Poikilotherms on the other hand do the exact

understand their metabolic process at various temperatures. Other studies show that although poikilotherms are viable at varying temperatures some organisms like the salmon still struggle to survive or succeed as temperature fluctuate (Brett 1971). The fish loses energy and at different stages of their life‚ they have different temperature tolerances that ultimately regulate the fish species overall population and success (Bisson and Davis 1976).

Rats are various medium sized rodents. "True rats" are members of the genus Rattus‚ the most important of which to humans are the black rat‚ Rattus rattus‚ and the brown rat‚ R. norvegicus. Many members of other rodent genera and families are also called rats and share many characteristics with true rats. A rat has an average life span of 2-3 years[1]. Rats are distinguished from mice by their size; rats generally have bodies longer than 12 cm (5 in). Contents [hide] * 1 Species and description

To be honest‚ I thought “Even the Rat was White” was a pretty interesting book to read because I got to learn more about racism in the white dominated field of psychology. I thought the book did a good job of covering the important facts of racism in psychology because when you look at psychology now in my opinion; it has become more diverse than ever. Before I read the book‚ I didn’t know if I was quite ready to read it since it was going to be about racism in the field of psychology. While reading

Synthesis paper 4.2 Shifting baselines Shifting baselines is a term used to describe or measure the change in a system keeping a reference point. This reference point is also known as a baseline which is usually taken from the past. The baseline can be any time period. It can be older than 50 years or 200 years from now depending on the situation and the availability of certain data‚ information and accurate statistics. “Shifting baselines are the chronic‚ slow‚ hard-to-notice changes
