Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

Week 2 Virtual Lab Score: 40/40 (100%) Week 2 Virtual Lab: The Cell Cycle and Cancer Worksheet 1. In which phase of mitosis do each of the following occur: a. Centromeres split and chromosomes move toward opposite sides of the cell occur during the anaphase. b. Chromatin coils to form visible chromosomes occur in the prophase. c. The nuclear membrane disappears occur in the prophase. d. Sister chromatids line up in the center of the cell occur in the metaphase. 2. In

Just below the surface The story is written by Kate Nivison and takes place in a London suburb in an upper class environment (p. 41‚ l. 14) in modern time (p. 42‚ l. 23). It is a first person narrator so we sympathize with Indrani. Indrani: * Is an Indian woman (p. 42‚ l. 37) * Is education‚ but not highly educated * She is very bigoted (p. 42‚ p. 29-30) * She thinks the British people are xenophobic (the woman in the shop and the men from the council‚ p. 43‚ l. 15) *

Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth‚ above the cemento-enamel junction‚ it is also possible for caries to form on the root surface‚ below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental

The changes in the diffusion of Buddhism and Hinduism through 600 CE greatly impacted these religions such as the popularity of the religions in India and where the religions was being diffused; however‚ a few continuities existed such as they both originated in India. Since Hinduism reinforces the caste system and Buddhism believe in equal treatment of all people which opposes the caste system‚ Buddhism started to spread into other areas other than India to offer an alternative to Hinduism for

Mitosis. Experimental Hypothesis: If we put onion root tips in IAA solution then the rate of Mitosis will increase. Null Hypothesis: There will be no difference Part 1- Post Lab Question If a cell contains a set of duplicated chromosomes‚ does it contain any more genetic information than the cell before the chromosomes were duplicated? No‚ because if it is duplicated‚ it would have the same number of chromosomes unless there was a mistake. Why do chromosomes condense before

potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying more kinetic energy the chance

fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. Fatty acids Fatty
