Question A 40.0 kg child takes a ride on a ferris wheel that rotates four times each minute and has a diameter of 18.0 m (a) What is the centripetal acceleration of the child? (b) What force (magnitude and direction ) does the seat exert on the child at the lowest point of the ride? (c) What force does the seat exert on the child at the hughest point of the ride ? (d) What force does the seat exert on the child when the child is halfway between the top and bottom? 

3. 4. A copper calorimeter whose mass is 250 g contains 700 g of water at 25°C. When 25 g of a certain metal at 98°C is immersed in the water, the resulting temperature is 30°C. What is the specific heat of the metal? The specific heat of copper is 0.093 callg Cº. If 8000 cal of heat is needed to change the temperature of a certain amount of ice at -25°C to steam at 135°C, determine the mass of the ice. The specific heat of ice is 0.50 callg Cº while its heat of fusion is 80 cal/g. The specific heat of steam is 0.46 callg Cº while its heat of vaporization is 540 callg.

Suppose four point masses are placed on a number line as follows: mi 12 kg, placed at x1 = -4 m 30 kg, placed at xz = 2 m m2 = 12 kg, placed at x2 = 4 m m4 = 6 kg, placed at X4 = -6 m. m3 = Find the moment of the system with respect to the origin and find the center of mass of the system

Explain the difference and similarities in mitosis and Meiosis. Next explain the terms independent assortment, crossing over, monohybrid, homozyogous, heterozygous, and dihybrid cross. Lastly give an example of genes that have lethal alleles. What does this term mean? Dr. TaylorAristapedia is a lethal allele that is also dominant. Individuals with this Explain the difference and similarities in mitosis and Meiosis. Next explain the terms independent assortment, crossing over, monohybrid, homozyogous, heterozygous, and dihybrid cross. Lastly give an example of genes that have lethal alleles. What does this term mean? Dr. TaylorAristapedia is a lethal allele that is also dominant. Individuals with this trait must be heterozygous (Aa) because the homozygous condition (AA) is lethal. This is not a sex-linked trait. Wild-type flies do not carry the allele for aristopedia (aa). 1. Predict what the outcome of a cross between a wild-type fly and one with aristopedia. Show the punnett square to illustrate your reasoning. 2. Perform the cross and determine if your prediction is correct using statistical analysis. Summarize your results and indicate whether your prediction is confirmed.

Part 1: Use PowerPoint to create a WBS in chart form for a web development project of your choosing (or you may select another type of IT project you are familiar with). It should be similar to the chart in Figure 5-4 from the text. Select an activity in Level 2 and decompose it into a level 3. Then select an activity in Level 3 and decompose it into a set of Level 4 work packages. Remember, WBSs are used to define the total scope of a project so your Level 2 should reflect that. Part 2: Recreate the same WBS defined in Assignment 5 Part 1 using Microsoft Project, GanttProject, or Microsoft Excel, indenting categories appropriately. Number the items of the WBS appropriately following the same format illustrated in Figure 5-4.

What evidence supports the conclusion that the SLC24A5 gene contributes to the production of melanin in humans in the same way it does in fish? Select all that apply. Hint: Review the section of the paper entitled “Conservation of golden gene structure and function in vertebrate evolution.” A)Injection of golden zebrafish larva with human SLC24A5 messenger RNA (mRNA) restores the fish’s ability to make melanin. B.)The slc24a5 protein produced by the gene in the zebrafish is 68 – 69% similar to the SLC24A5 protein in humans. C)At least 93% of East Asians share the same G allele of the SLC24A5 gene with Africans, yet East Asians are usually light skinned. D)The zebrafish slc24a5 gene and the human SLC24A5 gene are both expressed at high levels in skin and eyes.
