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

Mitosis is a way to help your body replace worn out cells. Mitosis has five phases‚ six if you include Cytokinesis. The phases of Mitosis are Interphase‚ Prophase‚ Metaphase‚ Anaphase‚ and Telophase. These phases all work together in order to help recover worn out muscles ‚ skin and other types of cells. Mitosis is when one cell divides into two daughter cells. Mitosis is very useful for organisms. Without Mitosis organisms would not be able to repair cuts and could result in death. It is also

Presence of Alu element within PV92 on chromosome 18 in a mixed ethnical population and its connection with humans’ ancestral origins By Shiyu Song Biology 155Q LAB-A: 14:30-17:30 Dr. Jacob April 17th 2013 Abstract The Alu insertion (+) within PV92 on chromosome 16 usually reflects a person’s ancestral origin. This study aimed to find the correlation between the presences of Alu insertion (+) within PV92 on chromosome 16 within a population. We used PCR to detect the Alu insertions

Effects of pH on the Function of Enzymes Rena Mototani Glen Rock High School Advanced Biology 2014-2015 Effects of pH on the Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The

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

Meiosis and Mitosis‚ and how do they ultimately affect the end results? The most prominent difference between the process of Meiosis and Mitosis is the number of divisions involved: Mitosis only has one major division whilst Meiosis has two. The divisions affect the overall outcome because they have a direct correlation to the number of daughter cells produced-- which is to say‚ the more divisions a cell undergoes‚ the more daughter cells it produces. In this specific context‚ Mitosis typically produces

Wanni Lin Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are

Brian Toohey Biology Mrs. Heimforth 12/06/10 Diffuse the Osmosis Section 2: Introduction Step 1: The scientific concept of this lab was to see how osmosis transferred the substance through the cells to reach equilibrium. Step 2: My hypothesis was that the bag with 60% sucrose then it would be heavier than the bag with tap water or 30% sucrose. I thought this because I thought that there would be more of a substance change in 60% sucrose. Section 3: Methods First get 3 pieces of the same
