Aveda Institute Syncitial Blastoderm Stage of Drosophila Embryos Questions
I have a biology questions assignment they are 4 questions total and they are a free response type of question. i will attach a document here that has the questions that needs to be answered, please look at them carefully since they have lots of details.QUESTION 11.Although BMP is present uniformly in the frog egg, and Chordin is present in a gradient, I described BMP but not Chordin as a morphogen. Explain why Chordin may not be considered a true morphogen. (3-4 sentences). 2.While studying formation of the dorso-ventral axis in the fly embryo, you learnt that several maternal effect genes, when mutated, cause a dorsalized phenotype. Only a single maternal effect gene, when mutated, gives rise to a ventralized phenotype. Explain how this discrepancy makes sense, in the context of what you know about the signaling pathway that is involved. (3-4 sentences)3.In the syncitial blastoderm stage of Drosophila embryos, nuclei move to the periphery and are held in their positions just beneath the plasma membrane by the cytoskeleton. This is important. Explain why it would be detrimental for pattern formation if the nuclei could freely move around and migrate to new positions. (3-4 sentences) 4.Transcription factors play essential roles in every aspect of embryogenesis. Explain why this statement is correct. (2-3 sentences

Documentary Discussion Questions
The video can be streamed on-line at the following sites:https://vimeo.com/arcosfilms/review/65772747/1ea0c...Discussion Questions:What in the film surprised you and why?List and discuss some of the many benefits of energy efficiency.Why are our personal actions toward energy efficiency and conservation so important?What delays efficiency measures and why can they be slow to have an impact?What are your thoughts on how the film measures and compares energy resources by the number of people (average global citizen) each would power in a year?What was your impression of the scale of energy consumption and production?What does it mean to clean up coal? Can we afford to?Did the film change your perspective on oil demand, supply and price?Why do various countries consume such different mixes of energy?How will the developing world change global energy consumption and the resources used?How are the environmental impacts of energy perceived in different parts of the world?What current and future biofuels technologies are discussed in the film? Which were not?Where would we get the electricity to power a huge fleet of electric cars? Why is this important?In what ways can natural gas be used as an energy resource? Why is fuel versatility important?What are the two kinds of solar, and how do they differ?What are the biggest challenges for large scale solar development?How does geothermal electricity generation work?What are the benefits and challenges for wind power?How do we consume electricity over the course of the day? Why is this so important?How would the ability to store electricity in huge utility-scale quantities change our electricity consumption and production?What are the benefits and challenges for nuclear power? What forms of nuclear are not discussed in the film?Why do energy transitions take time?Were there any emerging energy technologies you would have liked to see in the film? And what are the benefits and challenges of each?What should be the role of government in energy?How can governments, industry, academics and other groups best work with the public to improve our energy future?

Highline Community College Chemistry Measurement And Calculations Question
Experiment 1weigh DRY pennies-- tare the weigh paper -- use analytical balancesCheck the pennies you use to make sure they fall into the correct date range before each trial. Then, KEEP TRACK of the pennies so they REMAIN sorted by date, by placing them into correctly labeled bags.Measure the volume using a 50 mL cylinder. Don't forget to write the decimal places on your measurement, especially if there is a 0.Repeat for 2 trials each-- pre- and post- 1983 pennies. Run the first trial all the way through before starting the second trial.In your calculations, report an EXTRA significant digit in your density. (Underline the last sig fig, and keep one extra.) This will include your measured values in the average, keeping your average as accurate as possible. Only round once, at the very end.To work in pairs, I suggest having one person run one set of pennies and the other person run the other set of pennies. Then you can share data after the trials are complete.Question 1For Part A, you will measure the volume of a small stack of pennies using volume by displacement (or water displacement), one of the methods used in Experiment 1. Briefly describe how you will use a 50 mL graduated cylinder and water to measure the volume of pennies by displacement. (In your notebook, consider sketching the graduated cylinder and water before and after the pennies are added.)List the measurements you will make and how they will be used to calculate the volume of pennies.Question 2Consider the data shown below for a rectangular metal sample. A student used an analytical balance and a centimeter ruler marked to every 0.1 cm, and recorded the following:Table 1: Experimental MeasurementsMass of Metal Sample77.51 gLength of Metal Sample4.5 cmWidth of Metal Sample1.6 cmThickness of Metal Sample1.6 cma. Calculate the density of the metal sample, expressing the final answer with the correct significant figures in the first box, and correct units in the second box. (Use the ^ symbol to indicate a unit raised to a power. For example, x2 would be entered as x^2.)D = b. There are two mistakes in this data, based on the type of instruments used to make the measurements. Identify the mistakes.The mass is recorded incorrectly because .The lengths are recorded incorrectly because:Question 3You will use a 50-mL graduated cylinder in this experiment to measure volume. Given that smallest marking on this graduated cylinder is 1 mL, circle all of the following sample measurements that are NOT appropriate or NOT recorded to the correct number of decimal places using a 50-mL graduated cylinder: 44.1 mL32.5 mL15.11 mL15 mL
