Science Study Notes Inner Space Structure of the atom · An atom is the smallest part of an element that can be part of a chemical reaction - in other words‚ an atom is the smallest particle that can exist naturally · When two or more atoms join up they form a molecule. Atoms are generally found in the form of molecules. · An atom consists of a nucleus‚ which is made up of protons and neutrons. · Protons are positively charged particles. Neutrons have no charge. There is an outer layer made

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

Some of the most bizarre and fascinating plants in the natural world are undoubtedly carnivorous plants. Carnivory‚ defined as the consumption of animal tissue‚ is often only associated with the animal kingdom. However the existence of carnivory is widespread and diverse in the plant and fungi kingdoms as well. Specifically carnivorous plants‚ which originally descended from exclusively photosynthetic plants‚ have evolved elaborate‚ efficient‚ and diverse methods to capture‚ digest‚ and metabolize

Plastic in the Ocean More than 200 animal species are dying everyday because they are consuming plastic in the ocean. This paper will discuss the environmental issue of polluted oceans‚ the causes‚ and possible solutions. The current environmental issue is littering in the ocean. Everyday hundreds‚ thousands‚ and even millions of trash is dumped into the ocean. Hundreds of marine species eat large amounts of plastic debris. “Yet the question is why so many species from the tiniest zooplankton to

Observing the and determining the reaction rate of photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is

They feed on other organisms for their source of energy. Fungi-A non-photosynthetic eukaryotic heterotroph. fungi can consist of yeast‚ mold‚ and mushrooms. They are not microbes. Some are pathogenic and can cause disease in humans and animals. Viruses-Acellular or non-living agent composed of nucleic acid surrounded by a protein coat. Prions-Infectious

TOK Human Sciences Essay: When compared to the natural science‚ it is difficult to consider the human science scientific. Defend or refute this statement. Introduction: There have always been debates on whether human science is considered scientific‚ especially when it is compared to natural sciences. In order to answer this question‚ I should first define the terms – science‚ natural science and human science. I define science as a systematic enterprise that organizes knowledge in testable
