In this chapter‚ you will learn about the neural system of human‚ mechanisms of neural coordination like transmission of nerve impulse‚ impulse conduction across a synapse and the physiology of reflex action. 316 BIOLOGY 21.1 NEURAL SYSTEM The neural system of all animals is composed of highly specialised cells called neurons which can detect‚ receive and transmit different kinds of stimuli. The neural organisation is very simple in lower invertebrates. For

Biology is a wonderful subject that many students enjoy. But as life would have it (no pun intended)‚ this study is not a favorite of the majority of students who pass through the halls of school. Here are a few questions about biology and some answers to them. So why do we study biology? A lot of students trying to get through school stare at the mountain of work this class involves and struggle through. Some rationalize that it’s good to be well rounded in science or just school in general

In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species

has a specific history‚ and started in a time where being “colored skin” is considered abnormal. While being white was the norm‚ at that time biology was important and science was influencing the population. Indeed‚ there were‚ are and will be physical differences between people. Yet‚ what is significant about these when it comes to race is not the biology of those differences‚ but the social weight we attach to them. Therefore‚ the race still exists not because it is biological or normal‚ but because

Chemistry plays an important part in studying Biology. It answers some questions that Biology could not explain alone. Questions like: How does an organism convert foods for energy? How do plants use sunlight and water into all the things that cells needed to grow and reproduce? How does the basic unit of life passed through generation to the next? Here are some contributions of Chemistry in Biology: • Within atomic theory‚ chemistry contributes towards biology in the understanding of atoms and elements

Marine Biology is the scientific study of organisms that are dependent on water. Marine Biology is an interesting topic to many people because of the exotic animals you get to work with. A career in Marine Biology can be dangerous because of the wild animals‚ but at the same time it can be fun. It takes time‚ training‚ and intelligence to succeed in the career. In order to make it in this Biology field you must complete a college work in oceanography‚ marine biology‚ or conservation. You will
