Briefly explaining the differences between negative feedback, positive feedback and feed-forward in physiological system with suitable examples

A feedback loop is a biological occurrence wherein the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback). Living organisms are able to maintain homeostasis through these feedback loops. This is the mechanism that enables us to keep our internal environment relatively constant. Examples of negative feedback include maintaining … Read more

The Abiotic and Biotic processes

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. It would be impossible to overestimate the importance of photosynthesis in the maintenance of … Read more

Bowlby’s Theory

Bowlby’s theory is an evolutionary theory because he believes attachment is a behavioural system that has evolved because of its survival and reproductive value. Caregiving is adaptive because species have adapted over many years to enhance survival of the offspring so they can later reproduce. Bowlby’s theory is made up of many different ideas. According … Read more

Babel-Fish Earbud Translators

Abstract This paper explores published articles from online resources (internet) that depict a probable solution to near real-time language translation in support of targeting, situational understanding, and/or information collection. As technology shrinks the distance between nationalities and cultures, language remains a barrier that still prevents a shared understanding between the pair. This paper will examine … Read more

Types of Seed Dispersal and Its Importance

In order for new plants to grow, seeds need to be distributed to different areas away from the parent plants. A disadvantage of plants compared to animals is that plants cannot physically get up and move themselves to different places.
