morphological tree and molecular data tree. The ribulose bisphosphate carboxylase (Rubisco) protein is essential to carbon fixation in photosynthesis and is found in green algae (charophytes) and all land plants (Campbell et al.‚ 2011). The gene sequence for the large subunit (rbcL) of the Rubisco protein has been isolated from a large variety of algae and plants. We hypothesize that the phylogenetic tree based on morphology and life cycle features would be an accurate depiction of land plant phylogeny based

Chapter 16 Notes Lesson 1: Composition and Structure of Earth’s Oceans Water covers 70 percent of Earth’s surface. The five main bodies of water are: The Pacific Ocean is the largest and deepest ocean. It is larger than all of Earth’s combined land area. The Atlantic Ocean is half the size of the Pacific. It occupies about 20 percent of Earth’s surface. The Indian Ocean is between Africa‚ India‚ and the Indonesian Islands. It is the third largest ocean. The Southern Ocean surrounds

tropics. As the name suggests‚ corral reefs are formed by colonies of coral polyps. Coral polyps secrete calcium carbonate (limestone) which forms the reefs. The polyps receive oxygen and nutrition through photosynthesis preformed by zooxanthellae algae. The necessity of large amounts of sunlights further restricts the environments in which these reefs can flourish. Reefs develop into three different formations. Fringing reefs occur along shorelines‚ and are frequently found on Hawaii and the Caribbean

[pic] Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla‚ families and genera have some species that live in the sea and others that live on land‚ marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment‚ and biology is the study of the organisms

the chemicals that gets released when it breaks down. Bisphenol A is a chemical that is harmful to marine animals in a number of ways. For example‚ algae gains it’s nutrients through absorption. Algae can absorb bisphenol A‚ which will affect the entire food web in the end. Small fish tend to eat algae and zooplankton‚ and when a fish consumes algae that has absorbed bisphenol A‚ the concentration of the chemical will increase for the fish through a process called bioaccumulation‚ which causes the

Cotton vs. Canola: A Sustainability Comparison By definition‚ sustainable agriculture is the production of food‚ fibre‚ or other plant or animal products using farming techniques that protect the environment‚ public health‚ human communities‚ and animal welfare. This form of agriculture enables us to produce healthful food without compromising future generations’ ability to do the same. Without sustainability‚ the world’s future generations of farmers will be faced with extreme agricultural issues

The organisms that were studied included periwinkles‚ sea stars‚ algae‚ urchins and different types of sea weed. Periwinkles have shells to reduce water loss and radiation effects. Sea stars also have a thick‚ impermeable outer layer to reduce radiation effects. Urchins are able to seek small crevices for shelter to reduce

Another interesting thing about sloths is that they have algae growing on their fur. The algae helps them survive because then they blend in with the leaves and grass. There are two kinds of sloths: 1) the two toed Sloth (like in its name it has two nails or claws)‚ and 2) the

domains of life? Why do some researchers believe that the Kingdom Protista should be split into more than one kingdom? In the early days of biology‚ all organisms were classified as either plants or animals. Single-celled eukaryotic organisms such as algae and Paramecium were assigned to one of the kingdoms according to whether they are photosynthetic or not. Fungi and prokaryotes were grouped with plants‚ because fungi are sedentary and prokaryotes have cell walls. A five-kingdom scheme was devised
