The Optimal Foraging Theory: Food selection in beavers based on tree species, distance, and size

The paper examines the relationship between optimal foraging theory and central foraging by using a beaver as a model. It also analyzes beaver food choice by noting species from woody vegetation, distance from water, status (not chewed and chewed), and the circumference of trees neighboring a beaver pond in South Carolina. Beavers avoid some species […]

More than a decade has passed since the scientists of the Human Genome Project and Celera Genomics finally cracked the code of life, the human genome. The publicly-funded Human Genome Project began in 1990, and the scientists worked in close cooperation with many US and international universities. In 1998, the private-held corporation Celera Genomics also […]

Sex determination of a person occurs in terms of the XY-mechanism (this heterogametic sex is male) and  includes three stages: chromosomal, gonadal, and phenotypic. The presence or absence of Y-chromosome is crucial for determining the sex. In the absence of the Y-chromosome, there occurs differentiation of gonads into ovaries and, as a result, a female […]

Evolution refers to the process by which living organisms gradually change from simple life forms to more complex ones over a long period of time. Studying evolution is crucial since it helps humans to comprehend their life history. Therefore, it is important to understand evolution because it is a focal point for scientific investigation into […]

Introduction After people eat, the food goes through their digestive system. The food material that the body does not utilize is egested from the body as feces. A basic process of digestion in humans takes place with the help of microbes. Some microbes in the digestive system and nature produce gas as a waste product. […]
