schmichael Brine Shrimp lab 2013 9/10/13 Introduction Artemia salina or (Brine Shrimp) belong to the Anthropoda phylum. Brine Shrimp are found in a variety of different habitats, ranging from temporary ponds to estuaries, lakes and rivers. A Brine Shrimp’s ability to inhabit various environments can be attributed to their tolerance of a range of salinities. Brine Shrimp have been found to survive in salinities from 0% to 15%. When hatching Brine Shrimp the highest number of eggs will hatch

Kendall Montgomery AP Biology Period 1 The Effect of Varying Light Intensities on the Location Preference of Brine Shrimp Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will prefer a chamber with significant light intensity because they need light in order to hatch and develop. Null Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will not have a preference. Procedure: The brine shrimp were placed in

Some do not know this, but Maine's central trade is not lobsters, for that precise reason, Maine is known as "vacationland" and lobsters accumulate travelers. So in the late spring of 2003, Gourmet Magazine sent the essayist David Foster Wallace to examine the ground zero of lobsters, the Maine Lobster Festival, MLF, in the heart of the mid coast area (wallace). One would envision the article would be a paean to lobsters and the exquisiteness of the Maine coast. Truth be told, Gourmet was a dream

It is suggested that the brine shrimp’s preference for green light is due to their food sources being predominantly green in colour. However brine shrimp are non-selective filter feeders who have no preference in what food they consume as they only consume what food is available to them at the time. This raises the question as to why the brine shrimp have an apparent preferred wavelength of light in this set of results. It could be assumed that the brine shrimp were raised in an environment where

theory of evolution. The hypothesis is also assuming an Ediacaran origin for arthropods, phenotypic evolution was w4 times faster, andmolecular evolution w5.5 times faster, during the Cambrian explosion compared to all subsequent parts of the Phanerozoic. These rapid evolutionary rates are robust to assumptions about the precise age of arthropods(Michael S.Y. Lee, et al., 2013). 2. The research focused on arthropods (insects, crustaceans, arachnids and their relatives), that are the most diverse

pesticides, grooming, and changes in sexual behavior. Health scientist beliefs are that they will eventually make a comeback. Along with learning about the different arthropods, this class has taught the students about other safety lessons and has given me a different outlook on “bugs”. The detection and importance of arthropods have changed the way that I view things. The things that you are familiar to think causes the bugs or insects to come around your living environment or your person, such

Microorganism: Prokaryote/ Eukaryote/neither: Average size (range & units): Unique characteristics (how is each microbe different from the others): Bacteria Prokaryote Cell wall are composed of peptidoglycan-a polysaccharide. Bacteria move with finger like flagella about 20 nm in diameter, which grow at the tip and rotate counterclockwise in bundles to cause runs and rotate independently clockwise to cause tumbles. Pili in bacteria is used to exchange of DNA. All bacteria have cytoplasmic membrane

very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 67,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects,

discovered. The species was found in Marble Canyon site at the north end of the Kootenay National Park in the Canadian Rockies in Canada, as part of the Canadian Burgess Shale fossil deposit on the Alberta B.C. border. The ancient predator was an arthropod that swam the Cambrian seas. Due to the fossil’s age it was determine that the creature predated the dinosaurs by some 250 million years, living 509 million years ago. Fossil evidence shows the creature was a marine species of about 10 centimeters
