SNC2D - Grade 10 Science Unit Test Review Key Cells, Tissues and Living Systems Plant and Animal Cells, Cell Theory, Cell Structure (p. 29, 30-32) The cell theory states that: Every living organism is made of one or more cells. The cell is the basic unit of structure and function. It is the smallest unit that can perform life functions. All cells arise from pre-existing cells. 2. How are prokaryotic cells different from eukaryotic cells? Give one example of each. Prokaryotic cells lack a true nucleus and do not have membrane-bound organelles.

Why don't cells grow indefinitely? Cells are limited in size because the outside (the cell membrane) must transport the food and oxygen to the parts inside. As a cell gets bigger, the outside is unable to keep up with the inside, and the cell membrane cannot supply the inside with what it needs to survive. Diffusion of nutrients throughout the cell also takes longer. What are 3 purposes of cell division? Growth (2) Reproduction (3) Repair What purpose does mitosis serve in the cell cycle? Equal distribution of genetic material between the two daughter cells Equal distribution of the cytoplasm and organelles between the two daughter cells (cytokinesis) Compare contrast diffusion and osmosis. Diffusion - movement of the solute from an area of high solute concentration to low concentration Osmosis - movement of water towards an area of high solute concentration Compare - both water and the solute move from areas of high concentration (water or solute) to low concentration Cancer (pp. 48-55) Define metastasis. When some of the cancerous cells break off from the primary tumour , spread through the blood and lymph and establish a secondary tumour in a new location. Describe the steps for a secondary tumour formation. Step 1: The primary tumour develops as a group of cells that are undergoing uncontrolled cell division Step 2: As the tumour gets bigger, it stimulates blood vessels to form and supply it with nutrients. Step 3: Tumour cells enter blood vessels and lymph vessels. This is dangerous because the tumour cells can move to other parts of body (metastasis). Step 4: Primary cells which arrive at new area of the body form secondary tumour s , which may eventually be fatal to the organism. How does a doctor diagnose cancer once he or she has located a tumour ? Biopsy (tissue sample) What are some reasons why cancer might recur after it has been successfully removed from a person? After surgery, a vast amount of the primary tumour is removed . H owever,

Calyx Corolla Essays

Calyx Corolla Essays Calyx Corolla Paper Calyx Corolla Paper Calyx Corolla 1)What is the gap in market structure for Calyx and Corollas business model? The traditional distribution chain for the fresh flower market is: grower, distributor, wholesaler, retailer and finally the consumer. As a result of the number of participants in this structure, a flower may be as much as seven to ten days old before it is available for sale in a retail store. Additionally, the industry participants do not confine themselves to a single role. For example, most growers distribute some flowers directly to local or more distant wholesalers, and many distributors and wholesalers engage in some of their own production. The fragmentation within the channels of distribution results in a rather inefficient distribution system. This gap in the fresh flower market structure was noticed by Ruth Owades who capitalized by creating Calyx Corolla (C), which is a true departure from traditional channels of distribution. The business model of C is as follows: orders from customers are received by telephone, fax, or mail at the central office in San Francisco and then sent via fax or computer to the thirty flower growers who supply C. The growers, in turn, pack and ship individual orders and send them directly to consumers by Federal Express. As a result, C is able to substantially reduce the time it takes to deliver flowers to the consumers door, typically only a few days after the flowers have been cut. 2) Evaluate the strengths and weaknesses of CC versus a conventional business retailer? What market segments is CC most suited to take advantage of? Strengths of Calyx Corolla compared to a conventional flower retailer: 1)The most obvious strength and the greatest competitive advantage that CC has when compared to a conventional flower retailer is the ability to deliver fresher longer lasting flowers. As a result of pairing growers with Federal Express, CC is able to deliver flowers within a couple of days of being cut as opposed to retailers that sell flowers that have already spent a lifetime in warehouses, trucks and storerooms. )CC not only sells a superior product compared to flower retailers, it also attempts to educate and inform its consumers. Among the product, cost and color choices in its catalogs, CC includes trivia, consumer information and arrangement suggestions to make the flower purchasing experience more enjoyable for the consumer. 3)As a result of its partnership with Federal Express, CC has the ability to distribute flowers to people all over the wo rld. Retailers, however, are generally located only in areas where flower demand is high and thus cannot reach as many consumers as CC. )The case states that CC is comparable to flower retailers in terms of flower prices charged to consumers. As such, flower consumers get more flower value (freshness and longevity) for their money when purchasing from CC. Weaknesses of Calyx Corolla compared to a conventional flower retailer: 1)Flower retailers offer consumers the ability to purchase and enjoy flowers real time, as opposed to CC which takes days to deliver flowers. 2)Although CC has six annual catalogues that allow consumers to see pictures of products, conventional retailers allow consumers to select from on-hand inventory. )Consumers who order from CC are required to pay a delivery fee, whereas consumers who purchase flowers from a retailer do not have to pay extra fees. As a result of CCs strengths, it is suited to take advantage of a couple market segments. The first is the seg ment of flower consumers who value quality fresh flowers that will last long after purchase. The other segment that C is suited to take advantage of is the group of flower consumers who live in geographic locations where retailers are unavailable. ) What should Owades and her team do to fully develop the potential of the C business model? What would you recommend? In my opinion, C has a strong business plan that has not been fully developed. Strategically increasing advertising, pairing up with a credible brand name and allowing consumers to customize floral arrangements are a few recommendations to grow the C business model. Reaching out to consumers via television commercials, magazine and newspaper ads, radio spots and billboards are all new advertising options for C. Currently 70% of Cs revenue is derived from its catalog, 20% from corporate clients and 10% from outgoing telemarketing to previous flower recipients and existing customers. By informing consumers about CC via these new advertising strategies, CC would increase brand awareness and revenue. Another recommendation for CC is to couple its distribution leadership with brand recognition. For example, CC could team up with Martha Stewart, Williams-Sonoma or Smith Hawken to sell brand specific floral arrangements. Additionally, since these brands are internationally recognized, this recommendation will attract a wide range of consumers. Finally, CC could set up a website that would allow consumers to customize floral arrangements. Based on the inventory of the 30 contracted growers, consumers could mix and match different flowers to create virtual floral arrangements. Once pleased with their arrangement, the consumer would place the order online and CC could use its distribution strengths to deliver the product.

Analysis - Case Study Example This case study also analyses the trouble a nonprofit organization goes through to ensure that they cater for the transport needs of the patients. It uses the example of Jeanne a patient who has to access the pharmacy store, which is two miles away (Sherman, 2011). Mary, who is the coordinator of the nonprofit organization in the region normally, represents other co coordinators. The case study brings out the efforts she puts in into ensuring that Jeanne accesses the pharmacy store. Towards the end, a committee composed of social workers and health providers is formed (Sherman, 2011). This committee is responsible for looking into the transportation plight in order to find a solution and despite mentioning possible solution; they all come to an agreement that the only solution is to purchase a number of vehicles to enable all the patients run errands effectively (Sherman, 2011). They also agree that this will need huge amounts funds for both the purchasing and maintenance procedures. The major problem presented in the case is the issue of transportation. If patients decide to use local public transport, they are very limited in their region of seventeen counties (Sherman, 2011). Therefore, the 900 HIV patients cannot all use the local public transport system. Volunteer transport opportunities are also present in the region but they are not readily available, hence unreliable. The patients can be either lucky or unlucky to get whereby they end up relying on probability. This therefore cannot be the solution in case of an emergency medical situation. The other available means of transport was the private transport. As much as this was available, the patients can hardly afford its high cost considering the fact that they have no family or friends to help with their finances and they barely earn a living. This problem is an imperative one since these patients need to
