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

Kalacas*‚ Hanna Mae Laluces‚ Ina Bianca Lanuza Department of Chemistry‚ College of Science *Corresponding author; e-mail: knight_BeNcH66@yahoo.com Abstract Chromatography is a powerful technique for separating and/or identifying the components in a mixture. There are different types of chromatography and each has its own strengths and weaknesses. In this experiment‚ pigments of the chili pepper were

In this lab‚ we extracted spinach pigments‚ and analyzed what colors of light these pigments absorb. By using TLC plate‚ hexane and acetone‚ I separated the pigments of spinach‚ and discovered that the main pigments were green and yellow. This works because with different polarities‚ pigments move at different rates. Hexane and acetone were also used to separate chlorophyll and carotene from spinach. Since they are polar‚ they can separate organic and inorganic things. From the experiment‚ I know

Title: Candy Chromatography Background Information and Research: Paper Chromatogrpahy is a analytical method that is used for seperating and identifying mixtures of color. There are two stages‚ the stationary phase and the mobile phase. The first is for a solid and the second for a liquid or gas. -Reference http://www.chemguide.co.uk/analysis/chromatography/paper.html Purpose: To see how paper chromatography works. Materials: · Candy with a colored coating‚ like Skittles® or M&Ms® (4 different

chloroplasts in water could release oxygen if light and an electron acceptor are available. In his experiment‚ oxygen was still being released without the presence of CO2‚ meaning that it had to be coming from the water. This discovery also showed that photosynthetic reactions are different than others because they give up oxygen‚ whereas others use CO2. Lastly‚ it showed that oxidation-reduction reactions are a major part of photosynthesis. Electron-acceptor molecules are being reduced and oxidized as electrons

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

effects of high temperature and chemicals on the permeability of the cell membranes. Beetroot contains a red pigment called betacyanin‚ which is located in the large central vacuole of the beetroot cells. The vacuole is enclosed by a single membrane called tonoplast and the whole cell is enclosed by cell membrane made up of phospholipids. As long as the cells and their membranes are intact‚ the pigment will remain inside the vacuoles. However‚ if the membranes are damaged‚ betacyanin will leak out and produce

Ecology Lab Report 4/17/12 Abstract Sampling Stomatal Densities of Various Species of Plants The importance of stomata is the fact that they control the intake of carbon dioxide and the loss of water in plants. The ratio of intake to loss creates a better picture of which plants adapt would to their environment and which would not. Eight different plant species were sampled the stomatal densities and compared them to their environments. The densities were recorded for each species

1. Name and describe the life cycle of plants. The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2. Contrast the life cycle of plants to that of animals: Typical life cycle: alteration of generation (plants)‚ diploid (animals) Resulting structure from meiosis: spores-plants‚ gametes-animals Occurrence of mitosis: gamete production-plants‚ zygote to individual-animals 3.
