INTRODUCTION Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species‚ ecosystem‚ biome‚ or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand‚ “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem‚ weather it is big one‚ or just ecosystem

Title- Protista Lab Concept- the concept of this lab was to explore what is in the pond water as living organisms and try to identify what it is. Some types of Protista are multi-cellular like giant kelp. Although they look much like plants‚ multi-cellular protists lack specialized tissues. Being eukaryotes‚ they have a membrane-bound true nucleus with linear chromosomes‚ and they have membrane-bound organelles. The kingdom Protista contains all eukaryotes that are not plants‚ animals‚ or fungi

groups of proteins in living systems. It is used to examine when and where proteins are being expressed‚ rate of degradation‚ modifications‚ how they interact with other proteins and more. The goal in this lab was to determine the similarities and differences in muscle proteins among 5 species of fish using SDS-PAGE and Western blotting. First‚ proteins are separated based on size. Second‚ antibodies are used to detect the protein of interest. Lastly‚ a substrate that responds with an enzyme is used

and animals. There are many types of Biomes on earth. BIomes are distinct from habitats‚ because any biome can comprise a variety of habitats. In our lab we had figure out the major components in a biome. For example‚ like the weather‚ what animals live in it‚ plant life‚ etc… And answer key questions to why something happens in a Biome. And how species and plant life depend on each other to survive in this biome. In order to answer this question we had to go to the school farm. We went out to the

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

sporophyte generation. These small openings are light sensitive‚ so they are most commonly located on the bottom of leaves to prevent dehydration. The stomata usually open in the morning‚ and close in the night in C3 and C4 plants. Although‚ many plants species are different when you compare their stomata orientation. One of the two major groups of flowering plants(angiosperms) are monocots‚ which include palms. These trees have adapted to harsh‚ dry environments. The deep roots of a palm tree allow it to

Determining the habitat preference of Artemia franciscana by creating artificial gradients of three abiotic factors: light‚ pH‚ and temperature Introduction In the study of ecology‚ species are often described as generalists if they live in broad environmental conditions or specialists if they live in narrow or specific environmental conditions (Reece et al. 2011). Artemia franciscana‚ the organism under study‚ is a well known generalist that has adapted it’s reproductive strategy to allow

Chemical Control and Salinity Tolerance of Invasive Species Acacia Nilotica (L.) Willd ex Del. in Puttalam Area ABSTRACT Acacia nilotica (L.) Willd ex Del. is an invasive species currently spreading in Puttalam area. It prefers to grow in arid climates with alkaline soil profile. It is becoming a troublesome weed in this area and therefore‚ the present study was conducted with the objectives of controlling the species by glyphosate application and find out salinity tolerance range
