the effect of the organic solvents on the cell membrane of the beetroot Objective: To investigate the effect of different organic solvents‚ such as alcohol and paraffin oil‚ on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator. Hypothesis: Organic solvents dissolve the organic matter in the cell membrane (such as phospholipids). This destroys the cell membrane‚ and the permeability of the cell membrane is disrupted casing red pigments to leak out by

In the Pre-K classroom I have been observing the past couple of weeks‚ I did Instrument 7.5 which is Visual Indicator and Oral Indicatior and Occurences which is how often Mrs. Valentine does something. Visual Indicators are certain things such as how many times does shes write on the board‚ uses overhead‚ points to or holds up a visual picture of something‚ shows a slide or film‚ demonstrates with model or equipment and other visual aspects. Oral indicators are providing or asking for examples‚

While I was observing Ms. Carrilo’s Pre-K classroom and interacting with the students‚ I saw that all three types of play— guided‚ spontaneous‚ and teacher directed play—was being used. After we all went inside of the classroom and settled down from being outside‚ half of the students went with the teacher assistant to the work area and half of the students stayed with the mentor teacher‚ Ms. Carrilo‚ at the carpet/block area. Ms. Carrilo said that she wanted one of the UTSA students to stay with

Describe the structure and function of each of the eukaryotic organelles. ”A eukaryotic cell is sectioned by internal membranes into different functioning categories called organelles. For example‚ the nucleus houses DNA‚ the genetic component that controls the cells activities. (Boundless. “Introduction” Boundless Biology). The Cytoplasm is the material between the cell membrane and the nucleus. It has a lot of responsibilities within the cell. It contains enzymes for breaking down waste and also

Biological Membranes: A simulation Introduction Diffusion is the process by which collisions between molecules cause to spread apart. This movement is described as movement from an area of greater concentration to an area of lower concentration. Hence‚ diffusion continues until the molecules are equally distributed. This is to ensure that molecules have reached a state of equilibrium. Diffusion occurs spontaneously‚ no energy is involved. In cells‚ Diffusion occurs through cell membrane which is

beet cell membranes Introduction: Cell membrane is the plasma like substance that separates different organelles and molecules within an organism. The cell membranes vital function is to permit passage of protein and enzymes through their wall. Red beets‚ also known as Beta Vulgaris has a red pigment that is located in its large central vacuoles. It is my hypothesis that if the cell membrane is to experience extreme temperatures‚ then it’s most likely it will affect the membrane. * I hypothesized

___________________ Classification of Body Membranes Purpose: What is the purpose of this exercise? Is there any safety concerns associated with this exercise? If so‚ list what they are and what precautions should be taken. The purpose of this exercise is to be able to classify the membranes and learn about each. In this lab I will observe each membrane. Basically just getting to know each membrane better. Exercise 1: The Microscopic Structure of Cutaneous Membranes Observations: Draw your sketch

ABSTRACT Two salient features of the K-12 Program in the Philippines are Spiral Progression‚ to ensure that what is learned at one stage will not only be carried onto the other but also strengthened and developed over time‚ and College and Livelihood Readiness‚ to equip the Filipino student with the skills necessary to be a productive member of the society in the 21st Century. It is only imperative therefore that all curricula under this program gear toward these objectives. Values Education‚ being
