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 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

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

1. Describe the function of the following pieces of safety equipment and how each might be used: a. Eye wash- To be used in the event of a chemical splash to the eyes. Should be used to flood the eyes for at least 15-30 minutes with water‚ flooding from the eye outward. b. Fire Blanket- To be used in the case of a small fire. Would be tossed onto flames to suffocate the flow of oxygen. c. Shower- Safety showers are designed to flood your body with water in the event of a fire or chemical spill

The Variation of Yeast Cells When Adding an Antibiotic Biology 1401- A October 21‚ 2013 Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was

underwent fMRI brain scans as they saw and heard information about 24 potential television pilot ideas. Among the fictitious pilots were a show about former beauty-queen mothers who want their daughters to follow in their footsteps; a Spanish soap opera about a young woman and her relationships; a reality show in which contestants travel to countries with harsh environments; a program about teenage vampires and werewolves; and a show about best friends and rivals in a crime family.

(3 points) The phase in meiosis where chromosomes exchange segments of genetic materials (Campbell‚ 2009). b. Explain why crossing over is important in meiosis. (3 points) Crossing over is the way that genes receive genetic traits from both of the parents. 5. What are the two main differences between mitosis and meiosis?

Extrachromosomal Inheritance: n. Inheritance of traits through DNA that is not connected with the chromosomes but rather to DNA from organelles in the cell. Also called cytoplasmic inheritance. Essay on “Cytoplasmic Inheritance” Inheritance of characters from parents to offspring is primarily dependant on the nucleus. Oscar‚ Her twig etc.‚ had established in 1870 itself the importance of nucleus in the hereditary transmission of characters. The discoveries of Mendel further provided the genetic

Lab 6. Drosophila cross( start) Melat Mebrahtu Lab Instructor: Professor Hicks Principles of Biology Lab II‚ Wednesday 1:00 am- 2:00 pm Abstract The goal of this experiment was to examine the Drophisila fly cross for which the result was seen in two weeks .The Drosophila melanogaster has been a model organism that was experimented in the laboratory. It is a small fruit fly that feeds on and lives on spoiled fruit. It is one of the most valuable organisms in genetics
