Cell Biology Lab - Homework 1 Due to the week of Oct. 6-10th This is NOT a lab group project. Do the work individually. You may use any source other than your fellow students. Show your work‚ use your own words and cite all references. 1. (20 points) The HeLa S3 cancer cell line is considered to be “continuous” due to acquired mutations that enable the cells to evade senescence. This property is one of several hallmark characteristics of cancer cell lines. Describe three hallmark characteristics

LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) In the event of a chemical splash to the eyes‚ flood the eyes for at least 15-30 minutes with water. Flush from the eye outward. If you were not wearing proper eye wear‚ a chemical could splash into your eye and would make it necessary to use this. b. Fire Blanket (2 points) Used in order to put out a small fire. If a small area of the lab caught

Lab 1 : Scientific Method 20 Table 2: Water quality vs. fish population 1. Based on the information in Table 2‚ (in the lab manual) what patterns do you observe? 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. 3. What would your experimental approach be to test this hypothesis? 4. What are the independent and dependent variables? 5. What would be your control? 6. What type of graph would

procedure‚ what is the name of the indicator used to identify the presence of CO2? Phenol Red 4. B. What color did the indicator turn after blowing air into the water through the straw? Yellow 5. A. What color did the indicator turn after the tube was placed under a light source for 30 minutes? Light red 5. B. Why did this occur? Because the light‚ water‚ and CO2 were creating photosynthesis. 6. List the four common pigments found in plants and their functions. 1. Anthocyanin is red or purple

configuration of DNA. 4. What did Sir Isaac Newton mean when he stated‚ “If I have seen a little further‚ it is by standing on the shoulders of giants”? A. He was only able to accomplish what he did because of the people who worked and studied before he did. 5. Defend the statement “Process skills are considered life skills.” A. One uses process skills to complete everyday task‚ such as choosing and using the right tools to complete a task or organizing a task. 6. Why must all three aspects of science be addressed

Ksenia Semina Evolution Lab ARR 3 Blast Lab Analysis: Gene 1: The 4 organisms that were looked at in the Gene 1 are bird‚ vertebrate‚ rodent and bony fish. From the Blast result the most similar gene sequence to the gene of the gene of interest is Gallus gallus collaged which is also a bird. They are the most similar because the Gallus has the highest max score out of all other genes and 100% for the ident and there is no difference in the e-value. The species is located at the bird’s branch

Lab 10: Cell Structure & Function Questions 1. For each structure identified‚ do you think its location affects its ability to function? Why or why not? (Hint: those buried deep in the cell probably do different things than those closer to the cell membrane) Structure does not affect function of the cells‚ cells have a particular structure that enables them to carry out their function in the best way. Everything in a cell is there to enable it to perform in the most efficient manner possible
