Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught

Genetically Engineered Foods or Organisms Genetically Engineered Foods or Organisms Biological Basis Genetically modified crops (GMCs) are plants having DNA altered through genetic engineering techniques. The goal is to introduce a new desirable trait to a plant that does ordinarily occur in the species. Desirable characteristics include resistance to environmental conditions‚ resistance to diseases and specific pests and production of a particular nutrient. Genetic

Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 2.2 Identify

Prokaryotic cell have vacuoles. Both cells have vesicles as well. Prokaryotic Cell Eukaryotic Cell The division amongst prokaryotes and eukaryotes is considered to be the most significant difference among groups of organisms. Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the

Introduction to Biology‚ Lesson 3 Essay Questions: Compare and contrast directional selection and disruptive selection‚ and provide an example of each. Both of these show the distribution of phenotypes. In directional selection‚ the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to move in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white‚ pink‚ or red

AP Bio Essay #1 To address this problem created by the lab tech‚ I would set up an experiment like the one we did in AP biology to identify the molarity of the unknown sucrose solutions. First I would pour an equal volume of each solution into beakers labeled A‚ B‚ C‚ and D. I would also have a beaker of the same amount of distilled water to serve as a control for the experiment. Then I would obtain several baby carrots‚ 4 per beaker. I would mass the groups of 4 potatoes before placing them

The Ethics of Genetically Modified Organisms Genetic engineering has become a seriously debated concern in society over the last three centuries. As scientists become closer to finding a way to accomplish it with new technology and less risks‚ the increasing concerns grow. People all over the world are looking for a way to eliminate disease‚ expand lifetimes‚ and preserve resources. When looking at the genetic engineering of many important factors in society such as religion‚ laws‚ and societal
