Big Idea 2 Biological systems utilize free energy and molecular building blocks to grow‚ to reproduce and to maintain dynamic homeostasis. Living systems require both free energy and matter to maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both

Introduction General Biology:- Biology as a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ origin‚ evolution‚ distribution‚ and taxonomy. It is a vast subject containing many subdivisions‚ topics‚ and disciplines. Among the most important topics as contained in Biology are five unifying principles that can be said to be the fundamental axioms of modern biology:- 1) Cells are the basic unit

Biology Exam Review Unit One – Biochemistry What is an isotope? Isotope - An isotope is all atoms of the same element that have the same number of protons‚ but they may have different numbers of neutrons in the nucleus. - This means that all atoms with the same atomic number can have different atomic masses. - Because they have the same number of protons and electrons‚ they behave exactly the same in chemical reactions. Radioisotope - The nuclei of some isotopes of an element are unstable

curiosity and love for the subject grew as I read his books and watched documentaries‚ such as Planet Earth. I am particularly interested in the animal behaviour aspect of the course‚ along with biodiversity and taxonomy‚ which I have covered in A-level biology. A personal interest in conservation resulted in my joining WWF. I am also a member of one of the top zoos in the UK‚ Chester Zoo where I am a regular visitor. This is not only a leisure activity but has become a way to further develop my interest

the study of the universe beyond the earth. The earth science that involves the study of structure and composition of the earth includes different branches such as geology‚ oceanography‚ meteorology‚ paleontology‚ etc. Life science is also known as biology‚ which deals with the study of evolution‚ development‚ distribution‚ structure‚ origin and function of the living things. It is categorized into different branches such as botany‚ genetics‚ zoology‚ medicine‚ etc. The mathematical science involves

1. Why do I want to be a Wildlife Biologist? Well after many years of living in the country and being a boy‚ I was always outside doing something. Me and my best friend from the age of about five were always on are four wheelers riding around in the field‚ going fishing‚ or going “hunting”. During furbearer season I always would try to trap on a ranch in front of our house or on a guys land down the road. When it rained you could always bet that I would be in the back of the field at a little mudhole

to be a Biological Technician. I being surrounded by the media made me realize my calling. For me this is an ideal career because of its occupation‚ its work environment‚ its job outlook‚ its education‚ its skills‚ and its wages. To begin with‚ biology is the study of living organisms‚ divided into many specialized field‚ such as Zoology (the study of animals) and Microbiology (the study of microscopic organisms). These technicians study living organisms and their relationship to the environment

“Biology gives you a brain. Life turns it into a mind” (Eugenides). Biology is the study of life. The biological community is changing everyday due to scientist. There is one scientist who has contributed many studies to the biological community and that is Robert Koch. This paper‚ filled with research‚ will explain the life of Robert Koch and his contribution to biology. On December 11‚ 1843‚ at Clausthal in the Upper Harz Mountain‚ which is located in the Northern Germany‚ Robert Koch was born

B. An example of Dr. Moalem illustrating the AP Biology theme of evolution when she tells us about how during the black plague in Europe‚ people with more iron in their system were more likely to die due to the bacteria that feeds on iron‚ but now the population is more like to survive because scientists found that iron could help people fight of other diseases‚ even though it was killing the body in other ways. C. Another AP Biology theme used in chapter I is the continuity of life is based
