Lizards are sometimes called “cold-blooded” because they depend on the surrounding temperatures to keep themselves warm.
Predict how the cell membranes of a lizard’s cells might change from winter to summer with respect to the amount of cholesterol they contain. Justify your predictions.
On this website, select one of the best practice strategies. Within each practice strategy, you will find three tabs: evidence of effectiveness, evidence of impact, and implementation considerations. In your initial post, use these key categories to address the following question: How effective is this practice? What kind of impact does this practice have? What are the top considerations in implementing this strategy in your community? Be sure to support your positions with APA formatted in-text citations and references from the assigned resource.
The assignment examine and analyze social, multi-cultural and environmental issues and their impacts upon managerial practice in the global hospitality industry.
For the first part of your project choose one type of the following for the animal that you are building::
For each type of system you choose, describe the benefits of the system and the costs of the system. This can be in a table:
Considering ethical questions is part of a marine scientist’s job. Part of being ethical is doing your homework and exploring all sides of an issue. Choose a current ethical issue in marine science, such as the use of genetically modified organisms (GMOs), conditions in fish farms, or another topic your instructor approves. Find two perspectives supporting one side of the ethical issue and two supporting the other. Be sure to use reliable sources, such as university web sites or newspaper/magazine articles. Create an outline with at least five points for each side. Then write a brief paragraph explaining what you believe an ethical choice around this issue is. Remember, ethical problems are difficult because both sides have valid points. Be sure to consider and discuss at least one point you think is valid from the side that you disagree with in your conclusion as you explain why your choice is the ethical one. Also, include a list of sources that you used. Two is the minimum for each point of view.
Briefly summarize in your own words:
(1) similarities in the processes of cellular respiration and photosynthesis
(2) differences in the two processes.
Which of the following is not associated with the conversion of proto-oncogene to oncogenea.
Part 1: The human body At the end of this lab, you will find a picture of skeletons posing. For this picture, find the Humerus, Radius, Femur, Tibia (both left and right sides). Treat each bone as a vector beginning at one joint and ending at the other (you can choose, but be careful about negative signs). Then find the x and y components of each bone vector in units of centimeters using a ruler. Once you have the components, express each vector in (i,j) notation. Lastly, once you have each bone in vector notation, find the magnitude and direction of each bone vector. You will have a total of eight vectors that you will submit, along with your notes and calculations.
Part 2: The Animal Body Now you will go online and find the skeleton of your favorite animal. Could be a horse, dog, cat, dinosaur, etc. Then print out a picture of its skeleton and repeat the process from Part 1 for that animal skeleton finding the position vectors for any four bones. If you simply do not have a favorite, Included the picture of a dinosaur skeleton which you may use.
Complete the following problems.
Restriction enzymes (REs), which cut D NA at specific sequences, are classic tools in molecular biology. Because of their specificity in cutting DNA, REs can be used to “map” DNA sequences by analyzing the fragments generated upon restriction digest, as in the example shown in Figure
from this gel, answer the questions that follow.
Number of fragments:
Having made it through Cell Molecular Biology this far, you are now an expert on cells and their molecular mechanisms. There are approximately 10,000 proteins in a typical cell that are synthesized through different routes of intracellular protein trafficking. Each of you will be given a different protein and its final location in the cell. Starting from the mRNA that is produced and released into the cytosol, describe in detail how the protein is translated and where this occurs. Additionally, describe how the protein is being processed and where, along with how it is being transported or further processed until it reaches its final destination.
Depending on your protein, many will have very different routes that they follow. Provide enough detail to complete 2 – 3 pages. This can be done by focusing in detail the more complex steps; What mode(s) of protein trafficking occurs ? Is your protein glycosylated? Does it have disulfide bonds? If it goes to the nucleus, what size is the protein? If it simply stays in cytosol, then you will need to provide more detail about its transcription and translation than given in class. If it goes to several organelles, just focus detail on one part of the process.
