• A migrating fish would be rapidly transferring substances across cell membranes. These substances would include sodium, water, carbon dioxide, oxygen, and steroids. Which of those would be most likely to be moved via active transport? Why?

What is the process to obtain biomass production

An example of an RCRA Corrective Action site is Boeing Plant 2 in Seattle, Washington. There was contamination of PCBs, PAHs, phthalates, semi-volatile organic compounds in the soil on-site and in surrounding waterways (including groundwater). Boeing still occupies the area and it is handling the cleanup, which is still ongoing. Part of their process has been implementing pilot projects that have reduced groundwater contamination by 98% (US EPA 2013). Since Boeing is still active on-site, RCRA Corrective Action is appropriate.

An example of a Superfund site is Quendall Terminals in the state of Washington. Located on Lake Washington, on 29 acres, this Superfund site was previously acreosote manufacturing and oil storage facility for many decades. Creosote, coal tar, and other hazardous chemicals have accumulated in groundwater, lake sediment and on land (US EPA 2019). While the lake is not used as a drinking water source, there are swimming beaches within a half-mile from the site (US EPA 2005). In 1999, the state’s Department of Ecology began contamination cleanup. Then in 2005, at the state’s request, EPA took over. The EPA requested the site’s responsible parties conduct a remedial investigation and feasibility study. The remedial study was completed in 2012 and the feasibility study completed in 2017 by the responsible parties. Public comments were received from September to October 2019 and the EPA’s final cleanup plan is scheduled (US EPA 2019). As the location is no longer in use and currently vacant, the CERCLA program is appropriate for this site. Additionally, there are plans to rezone and repurpose the location for residential use.

Place the following energy states in order of their least net carbon dixide emission into the atmosphere, where 1. = lowest net carbon, and 5. = highest net carbon.

In your calculation, take into account:

A set of data was recorded for the reaction of decomposition of H2O2. The data is shown in table 3 Copy the data from table 3 in an Excel spreadsheet. Table 3 Time (min) [H2O2] 0 0.300 1 0.221 5 0.107 10 0.065 15 0.047 20 0.037 In Excel, add two columns to calculate the ln and inverse of the concentration. Make a prediction (guess) which order the reaction is with respect to H2O2. Plot the data and see if the plot obtained is linear, if it’s not change your prediction (guess again). For example, if you predict that the order of the reaction is zero, you will plot the data in the column [H2O2] vs time. If the plot you obtain is liner, you will have found out that the order of the reaction with respect to H2O2 is zero. If the plot is not linear, you will conclude that the order of the reaction with respect to H2O2 is NOT zero but you still will not know if it is first or second order. To find out, you will have to build another plot until you find a linear one.

When you finish, answer the questions below 1. Which plot is linear? 2. What is the order of the reaction with respect to H2O2? 3. What is the value of k? 4. Write the rate law for the reaction.

We are in an extraordinary and frightening period of world history, facing the type of crisis that, hopefully, we only see once every century or two. You know that two or three years from now, Hollywood, if it survives, will be releasing the “Corona Virus Film”, whether that is the appropriate or ethical thing to do or not.

         What do you think this film will look like? How will filmmakers look back in time and tell the story. Sadly, we do not know where we will be in a few years and what the true global impact will be. For this assignment, I want you to be the filmmaker. What story do you tell? How do you tell it? What characters and visuals do you use to tell the story? Where do you set it? What is the ending? We are all a small part of this film you are creating. Please be thoughtful, respectful and creative in your work. This is a crisis that is impacting all of us and your film needs to reach a global audience.

         Your paper should be between two and three pages,

Please select one section of the geologic time scale and do the following:

1. Select one part (either a period or an epoch).

2, What types of fossils can be found? What about major rock types? Geologic conditions? Geologic structures?

3. What types of organisms lived during this time?

4. Where there any major geologic events (massive volcanism, meteorite impacts, extinction events)?

5. Include references where you found your information.
