Guide 1. Definitions a. Metabolism- The process by whichc a living organism takes energy from its surroundings and uses it to sustain itself‚ develop and grow. b. Photosynthesis-the process by which an organism uses the energy from the sun to produce its own food c. Autotrophs- organisms that are able to produce their own food d. Heterotrophs- organisms that cannot make their own food and must obtain it from other organisms e. respiration -- the process by which food is converted into usable

of the animals. The kingdom monera contains primitive organisms. These organisms are very small‚ single celled and do not have a nucleus. They consist of prokaryotes which include species like the bacteria‚ archae bacteria‚ cyanobacteria and mycoplasma. Also‚ some bacteria are beneficial to us‚ such as the ones found in yogurt. But others can cause us to get sick. The kingdom protista as the kingdom monera contains single celled organisms. But these are different of the previous ones because of

more beneficial than the shell because it is now internalized and doesn’t weigh down the organism‚ the organism is now able to float horizontally in water and allowed the organism to develop fins for better locomotion. The loss of the shell also allowed the organism to have a highly contractible mantle cavity to squirt out water violently‚ moving the animal by jet propulsion‚ this further insured the organisms safety by allowing it to travel faster and further. The adaptation

metabolism. Cells‚ the basic units of life‚ can perform many of these metabolic reactions. In a multicelled organism‚ the cells group together to form tissues that perform the same functions. Tissues group together to form organs‚ and finally‚ several organs exist together in a system. In this lesson‚ we will see how and why this hierarchy is established.

Invasive Species have been described as an organism which is not native‚ and causes negative effects on the ecosystem‚ and to the health of humans. These organisms can be Fauna‚ Flora (Flora and Fauna refer to plant and wildlife‚ respectively)‚ a fungus or a bacterium. However‚ not all introduced species are invasive‚ but invasive Fauna and Flora‚ have been said to be the 2nd greatest threat to biodiversity post habitat loss. In his book‚ Invasive Species in a Changing World‚ Richard J. Hobbs (2013)

enhancements‚ stem cell research‚ cloning‚ genetic engineering‚ and genetically modified organisms. Biotechnology is “the manipulation of biological systems and organisms through technological means”(p. 471). There is tension between valuing liberty to pursue happiness of biotechnologies‚ and the potential negative outcomes of these technologies. Bioengineering‚ is the construction of machines to alter or supplement organisms. Biotechnologies result in therapeutic effects or extraordinary forms of enhancement

Cycle Living organisms are significant in the recycling of numerous elements contained in an ecosystem. One of the elements is carbon. Carbon is nonmetal‚ forms over ten million different compounds‚ found in minerals‚ oceans‚ and is the main component of biological compounds. So how do living organisms and their biochemical reactions contribute to the recycling of carbon? Carbon moves through the ecosystem in a cycle‚ in which the living organisms take and release different

occur in various living organisms. Chemistry is the one science in which all the other sciences are based. In biology you learn about living organisms and their composition. Organisms are alive because of chemistry - Why we breathe oxygen‚ how we make energy‚ elimination of waste products‚ cellular respiration‚ etc. All of these are based on how living organisms use chemistry to live. Biological organisms have chemical compositions. Carbon is found in all living organisms. After that‚ because there

Linneaus distinguished himself by classifying living organisms ac- cording to their similarities and differences. Classification schemes came to be based less on similarities and differences in form and more on evolutionary relatedness among species. Species that diverged from the same ancestors were grouped into the same categories. Cells: Matthias Schleiden and Theodor Schwann‚ both proposed the cell theory‚ which states that all organisms are composed of cells and that all cells come from
