A sample of biological culture was submitted to a chemical laboratory for analysis of the percentage by weight of each major element. The composition of the cells by weight was found to be 48.9% C, 5.2% H, 24.8% O, 9.46% N, and 9.2% ash.

  1. Prepare an empirical formula for the cells

  2. Determine the COD/organic weight ratio for the cell

  3. Determine the theoretical oxygen demand including both COD and NOD

    (nitrification oxygen demand)

  4. If the organics are 80% biodegradable, what is the ultimate BOD of the sample?

  5. What is the TOC?

Summarize this: Biological, Chemical, & Other Non-Nuclear Threats Biological, chemical and other non-nuclear threats, such as cyber and drone attacks, constitute a class of weapons that may not cause as much mass physical destruction as nuclear weapons can, but can result in significant mass effects on, and/or mass disruptions to, a targeted populace. Weapons experts still debate whether these non-nuclear weapons can truly be considered weapons of mass destruction; however, certain types of biological weapons, such as weaponized smallpox or...

In the laboratory, it is possible to culture the pollen of some angiosperm plants and produce a fully differentiated plant individual that does not result from fertilization. This plant individual produces perfect flowers but is sterile. By treatment with colchicine, the plant produced from non fertilization can be made "artificially" diploid and now the plant is fertile. How can you explain the haploid angiosperm is sterile and when made diploid becomes fertile?
