Segmented influenza RNA genomes specifically enable 

These mobile genetic elements can disrupt genes due to the random nature by which they insert into the host genome.

All virus particles must consist of, at a minimum (choose all that apply):

Gram-negative bacteria may not be as susceptible to cell wall inhibitors due to the presence of an outer membrane.  This is an example of

True or False: A temperate phage can undergo the lytic cycle.

Which polymerase is responsible for transcribing viral mRNA?

Answer 1 of the 3 questions listed below. Please indicate clearly which question (1,2, or 3)  you are answering. Optional: answer one additional question for up to 8 points of extra credit 1. Distinguish between the short-term biologically-driven global carbon cycle vs. the long-term rock carbon cycle. Outline the basic processes involved and the time scales on which they play out. If either of the two were to be able to help offset increased atmospheric CO2 due to human activity, which would it be (hint: how would increased delivery of organic carbon to the deep ocean, or storage of organic carbon in terrestrial soils) be expected to influence the size of atmospheric CO2 pool? 2. List six major organic carbon oxidation reactions in order of decreasing free energy release, which corresponds to their sequence in terms of “biogeochemical zonation”. How is this phenomenon involved in controlling the production of methane in marine sediments that under the appropriate condition can lead to methane hydrate formation? 3. Where in the marine environment does most organic carbon (and pyrite) burial take place? Why (in simple terms) is that the case? (hint: think about the relationships between primary production, water depth, organic carbon deposition, and the impact of sediment O2 availability on organic carbon preservation).

A. Mandatos de tú: Cómo salir bien en tus cursos en línea. Todos tus cursos están en línea este semestre y tu profesora te está dando sugerencias para que tengas éxito. Lee sus consejos y completa los espacios en blanco usando el verbo correcto en la forma del mandato de tú, según el contexto. (2 ptos. cada respuesta: 1 pto. por el verbo correcto y 1 pto. por la conjugación correcta del mandato informal; 10 ptos. en total)   MODELO:  No hables (hablar / llenar) inglés en tu clase de español.   Aquí tienes 5 consejos para mejorar tus clases en línea: 1. (crear / jugar) tu propio espacio de estudio. Un espacio tranquilo te permitirá tener una mente clara.                                                                2. (eliminar / repetir) las distracciones. Los mejores estudiantes en línea saben cómo reservar tiempo para concentrarse.   3. No  (contestar / olvidar) crear un plan de estudios. 4. (participar / seleccionar) activamente en tus clases. Aunque no interactúes directamente con otros estudiantes, es importante compartir tus ideas y contribuir a los debates.  5. No (comprar / esperar) hasta el último momento para completar tus tareas. En una clase en línea, es importante ser responsable y proactivo.
