 Importance of Photosynthesis

Discuss your understanding of how photosynthesis has made the earth’s atmosphere unique in the solar system. What effects would decreasing levels of photosynthesis have on human society over time, and what could we do to stabilize photosynthesis over the long-term?

Your answer should be at least 250 words and must substantively integrate the assigned readings from the module with proper APA (Links to an external site.) Style formatting// you may use additional sources and materials as long as they are relevant to the discussion and cited properly. Every answer should have its own reference. Do not write the references on the bottom of the page for all of them, need to do it individually.

 Effects of Wildfire

What are the positive and negative effects of wildfires? Are the effects primarily restricted to rural areas, and therefore, of little importance to the bulk of society? Defend your statement.

Your answer should be at least 250 words and must substantively integrate the assigned readings from the module with proper APA (Links to an external site.) Style formatting// you may use additional sources and materials as long as they are relevant to the discussion and cited properly. Every answer should have its own reference. Do not write the references on the bottom of the page for all of them, need to do it individually.

 Geographers and Plants

Why do geographers study plants more than they study animals (outside of humans anyway)? Why would the study of one tend to benefit human society more than the other? Justify your answer.

Your answer should be at least 250 words and must substantively integrate the assigned readings from the module with proper APA (Links to an external site.) Style formatting// you may use additional sources and materials as long as they are relevant to the discussion and cited properly. Every answer should have its own reference. Do not write the references on the bottom of the page for all of them, need to do it individually.

Task

back to top

Your job in this assignment is to create two Virtual machines each running a different but the latest distribution of Linux e.g. Ubuntu Server and/or CentOS Server. Each of these VM’s is to offer services to a user base.

The Virtual Machines can be implemented using any hypervisor e.g. VMWare Player, Virtual Box or anything else you think is appropriate. 

You can use bridged or host-only networking when setting up these Virtual Machines. When implementing the Virtual Machines, rather then obtaining an address from the HyperVisors DHCP server you should ensure the addresses used are static and assigned from your network. YOU WILL NEED TO WORK OUT WHAT ADDRESS SPACE YOU ARE USING AND HOW IT WILL IMPACT YOUR LAN.

Part 1: Virtual Machine One – DNS & SSH Server (5 marks)

The first Virtual Machine should be installed and have the BIND9 (DNS) server installed on it. While you do not own any address space/ namespace your name server should manage the following domains:

LastNameStudentID.org.au

The name server should answer queries for this domain. In addition to the saffioti.org.au zone, a zone should be set up for the reverse zone – the reverse zone would be whatever the address range is of your virtual machine. You should do some research on how Bind handles reverse zones.

You should set up the itccsu.org.au zone with the usual information including SOA, NS and other records where appropriate. The address used for this should be the address of the virtual machine. You should give this Virtual Machine an A record with the name server1. You should also create a A record for server2 (part 2 of this task)

In addition to this, you should create a CNAME record with the name www. When a user does a lookup on www.LastNameStudentID.org.au– the address returned should be that of the other virtual machine (Virtual Machine Two).

Be sure to create the appropriate reverse (PTR) records for the machines and to help other administrators be sure to put in place appropriate TXT records.

Once complete, you should fine-tune your DNS Servers Virtual machine. Do this by disabling services that were installed but are not required. Be very careful not to break anything here. As a tip, you will want to keep both DNS and SSH services active. Ensure both DNS and SSH are invoked at startup.

Finally, harden this Virtual Machine using a firewall. Set up filters which allow access to the services possibly being access on the Virtual Machine from other hosts – specifically SSH and DNS. You can assume this incoming traffic can come from anywhere. You will need to make sure these rules always take effect at boot.

Test your virtual machine by setting your Host computer (i.e. the computer that is running the VM) Name Server to the address of the Virtual Machine. See if you can resolve queries for the A records create in LastNameStudentID.org.au i.e. server1 and www.

Document the entire process and challenges you experienced. You can install BIND from source or using your package manager.

Part 2:  Virtual Machine Two (5 marks)

The second Virtual Machine is to have the LAMP software package installed. LAMP is a standard bundle in the Ubuntu Server platform.

Once complete set up this Virtual Machine to host a website using the Apache Web Server.

The Virtual Machine should have a statically assigned address which matches that specified in the A record for host www.

Test your Apache Server Virtual Machine by using a web browser on another host and trying to browse the website LastNameStudentID.org.au.

Once you have set up the web server and tested it, install a FTP server. The FTP server would allow users to upload/ download files to the web server. Configure the server appropriately and then test from another host.

Finally, harden this host so that only services being used can be accessed by other machines. You will need to use IPTables.

Document the entire process and challenges you experienced.

Part 3: Simple Web Services (5 marks)

In Virtual Machine Two, you set up a web server for the DNS name www.LastNameStudentID.org.au. The server is implemented using the HTTP protocol listening on port 8080. Your challenge is to make the same site accessible using the HTTPS protocol. To do this set up SSL with a self-signed certificate for the site.

Once configured correctly you should be able to access www.LastNameStudentID.org.au on both HTTP/HTTPS ports. Naturally, you will need to make appropriate changes to your firewall rules.

Document the entire process and challenges you experienced.

Presentation

You should submit your assessment in a single word document which contains all components of your assignment. Use screenshots to provide evidence and details of the work you have done to complement your written answers. You should reference where appropriate using an approve referencing style to support your work.

Statistics

2.Suppose the average commute time of your employees is unknown. The standard deviation of their

commute time is estimated as 28.4 minutes.

How many employees must be included in a sample to a 99 percent confidence interval for the average commute time with a confidence interval width of no more than 20 minutes?

Note that the correct answer will be evaluated based on the z-values in the summary table in the Teaching Materials section.

Remember to round your answer up to an integer.

Note that the correct answer will be evaluated based on the full-precision result you would obtain using Excel

Chemistry

Based on the paper by Prusiner[1], please describe in one page or less how one of the techniques in the paper (HPLC, proteolysis, Edman degradation, amino acid analysis, SDS page or what not) was utilized to provide information on the nature of the scrapie agent.

The paper should include:

1) Date

2) A title (“The use of xxx in the study of scrapie” by (your name) (or something like that).

3) The hypothesis of the paper (in your own words). “In order to support the notion/idea that scrapie is a protein” for instance. This is then followed by:

4) Specific reason for choosing the method by the authors (related to the hypothesis).

5) The method in detail, and what information can be gleaned.

6) What the technique that was utilized showed in the paper, data that was obtained, and how it contributed to the hypothesis. And finally…

7) Conclusion (this should be short and succinct) – please summarize the use of the technique in one or two sentences and how it helped understand the nature of the scrapie agent.
