ADRIANO‚ RN 0261849 ------------------------------------------------- NATURAL SCIENCE 1 CHAPTER 1 INTRODUCTION TO BIOLOGICAL SCIENCE Biological science is the study of living things. In this context we may ask: What are living things? We humans‚ ourselves are living things. How do living things differ from non-living things? To answer these questions‚ we must first define the word life

Biology 1C March 3‚ 2011 Extreme Environment of Lake Vostok in Antarctica Throughout the earth‚ there are so many places that are so extreme that we thought that no living things could adapt to the environment. Interestingly‚ there are some organisms that can inhabit in extreme environments‚ and they are extremeophiles‚ which are microbes that can thrive and adapt under extreme conditions. There are many types of extreme environment‚ such as extremely cold or hot‚ too acidic‚ lacking of water

2:30-3:30 TTHS Levels of Organization in Organism In unicellular (single-celled) organisms‚ the single cell performs all life functions. It functions independently. However‚ multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism. The cells become dependent on one another. Multicellular organisms have the following 5 levels of organization ranging

mainly about the different species he saw on the Galapagos Islands. Each island had a different variation of birds. He noticed that the beak sizes of the finches were different on each island because of the size seeds they ate. Darwin noticed that organisms reproduce more offspring than can survive. Each individual offspring has unique characteristics that can be hereditable. Most of Darwin’s observations focused on the idea of natural adaptions. Darwin noticed that the body parts an animal used

Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting.

Analysis of the oldest sedimentary rocks provides evidence for the origin of life • Identify the relationship between the conditions on early Earth and the origin of organic molecules Notes THE AGE OF THE EARTH - based on geological‚ magnetic‚ radiographic and paleontological studies: aged 4.5 billion years - Hadean eon: formation of earth from gaseous cloud to solid body. Heavy molten iron sank down and became the core‚ lighter rock came to surface = crust

Evolution of the Regenerative Properties in Crayfish Regeneration is the biological mechanism whereby organisms restore lost or damaged cells. This process can be used to replace organs‚ tissues and limbs on a small to large scale. Each type of regeneration requires different amounts of energy‚ resources and time. Orconectus rusticus (crayfish)‚ compete for food‚ survival and mating. They have large claws that are vitally important in competition and survival. This species has developed the

life because for wise men living is something totally different to staying alive. For them‚ life’s just too short to live. All the organisms perform some basic functions to keep themselves alive. The basic functions performed by living organisms to maintain their life on this earth are called life processes. The basic life processes common to all the living organisms are: Nutrition and Respiration; Transport and Excretion; Control and Coordination (Response to stimuli); Growth; Movement and Reproduction

Ksenia Semina Evolution Lab ARR 3 Blast Lab Analysis: Gene 1: The 4 organisms that were looked at in the Gene 1 are bird‚ vertebrate‚ rodent and bony fish. From the Blast result the most similar gene sequence to the gene of the gene of interest is Gallus gallus collaged which is also a bird. They are the most similar because the Gallus has the highest max score out of all other genes and 100% for the ident and there is no difference in the e-value. The species is located at the bird’s branch
