trees (spruce and pine) are adapted to the climate by having smaller‚ prickly leaves with waxy cuticles to reduce water loss and do not defoliate in winter. The advantage of this being that the trees may take in all the available sunlight for photosynthesis. The branches on such trees tend to be slightly elastic and bend under the eight of snow causing it to fall off and expose the leaves to the sun. The trees also have very shallow roots due to the continuous permafrost that restricts growth and

Biology is a natural science concerned with the function‚ growth‚ structure‚ evolution and distribution of organisms. It is the science of life‚ involving the study of all living things ranging from the atomic to ecosystem level. Far from being a science restricted to universities and laboratories‚ the principles and findings of biological sciences have uses in everyday life. Human Health · When people get sick‚ they visit the doctor‚ who is a practitioner of medicine‚ the branch of biology

Challenges in the Field of Marine Biology No matter what science oriented profession one chooses to pursue‚ education is the undisputed key to success and the field of marine biology is no exception. While a bachelor’s degree qualifies you for an entry level position‚ it is most likely insufficient if you have your sights set on a career involving independent research or field work. The majority of people working within the field of marine biology with only a bachelor’s degree‚ are for the

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

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

Autoradiography is a technique used to trace the movements of certain substances around plants. An example of this is carbon 14. Carbon 14‚ a radioactive isotope‚is added to the carbon dioxide supply of the plant‚ to study the movement of products of photosynthesis. Positron Emission Tomography (PET) uses a camera to detect gamma rays emitted from the body and to pinpoint their exact location. Disease may be indicated if an organ takes up too much isotope‚ or not enough‚ or if there is an unusual pattern
