Abstract

Animals whose body temperatures are affected by their surroundings are said to be ectothermic. If an ectothermic organism is exposed cold conditions, the heart rate of the animal lowers. In high temperatures the heart rate of the animal is very high. Caffeine being a stimulant works by causing the nervous system to work faster. It further leads to the constriction of the blood vessels. The Daphnia magna sometimes referred to as the water flea lives in the fresh waters. It is an exothermic crustacean. The results of Table one shows that Daphnia’s heart rate lowers as temperatures the Continue reading...

Abstract

Caffeine is a widely-used drug that modifies the psychological condition of the consumers. At high doses, it causes various caffeine-related symptoms such as agitation, as well as the restless legs syndrome. Since caffeine is a habit forming drug, it allows the development of tolerance and withdrawal symptoms. It also alters sleep patterns in accordance with the consumed daily caffeine dose. Although its arousal of the central nervous system can induce pleasant effects at relatively lower doses, caffeine can impair concentration and attention at increased doses. The present study, therefore, examines the various adverse effects of consuming caffeine at high Continue reading...

People used to think that if they ate a certain animal, they would acquire some of the characteristics of the eaten animal. People now think that if they ingest certain chemicals that enhance the performance of a laboratory rat, they too would develop greater power.
Athletes, and others, are in constant search for the latest supplement— hopefully legal— that might enhance their performance and make them better athletes. But, for most supplements, the evidence is weak, or completely lacking. Nonetheless, there are a few dietary supplements, including caffeine and creatine, that have been shown to help.

Introduction

Teratogen is broadly defined as an environmental agent capable of causing abnormal prenatal variation in form or function. In other words, it can be any environmental factor that can produce a permanent abnormality in structure or function of an embryo or fetus or restriction of growth of an infant (Gilbert-Barness, 2010). In prenatal life, exposure to teratogens may even lead to death of the embryo or fetus. It is estimated that approximately 15% of all congenital structural abnormalities observed in a child are due to exposure to some kind of teratogens during the prenatal life (Brent, 2001). A larger Continue reading...
