Our planet is blessed with biodiversity composed of prokaryotes and eukaryotes. Almost all of them have specialized systems of sensing light‚ sensory and/or motor response composed of a cell‚ tissue or organ like eyes and brain. The Pax (Paired box) genes and proteins have been observed critical during formation of such tissues or organs and Pax family transcriptional regulators remain critical to maintain their functional anatomy. The Paired Box 6 (Pax6) best exemplifies the conservation of functions

(TC)‚ Triglycerides (TGL)‚ High density lipoproteins were purchased from Erba Mannheim‚ Transasia Bio-Medicals limited‚ Himachal Pradesh‚ India. All other chemicals were of analytical grade. The experiment was conducted using [12] male Albino Wistar rats (150-200g)‚ at about 6-8 weeks of age. All the animals were procured from Sanzyme Ltd‚ Hyderabad‚ India. The animals were housed in poly acrylic cages (38cm x 23cm x 10cm) which have the capacity to carry six animals per cage. They were exposed to

franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

Heart rate in black worms with and without added glucose Introduction: The circulatory system is important in circulating blood‚ nutrients‚ oxygen and chemicals to the body. A circulatory system commonly consists of the fluid it contains‚ such as blood‚ a pumping vessel such as a heart‚ and the vessels‚ which carry the fluid through the body. In a closed circulatory system‚ the fluid‚ blood‚ is contained within the vessels as it circulates through the body. The Lumbriculus variegates‚ or

Sedimentator Lab Introduction: in this lab we will be working with a sedimentator to observe and classify sediments. A sediment is naturally-occurring material that is broken down by processes of weathering and erosion‚ and is subsequently transported by the action of fluids such as wind‚ water‚ or ice. Side One Purpose: to observe and classify sediments Part I 1. Gently shake the sedimentator to loosen the sediments and lay the sedimentator on its side 2. Observe the water

Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential
