Dos pequeñas esferas cargadas se encuentran fijas en el espacio, separadas por una distancia de 0,5m. Sus cargas son q_1 = 2\,\mu Cq1​=2μC y q_2 = 3\,\mu Cq2​=3μC. ¿Cuál es la magnitud de la fuerza eléctrica que una ejerce sobre la otra?  

Un disco de radio posee una densidad superficial de carga uniforme

Which statement is false for why men volunteers and fought during the Civil War.

Which battle/campaign was not a Confederate Victory?

Which statement(s) are correct about military conscription (the “draft”) during the Civil War.

In terms of American Civil War history, what does the term “antebellum” mean? 

What is the direction of new DNA synthesis catalyzed by DNA polymerase?

The drawing below shows an E. coli DNA replication fork just left of where replication begins.  On the diagram the following conventions are used:   Grey, rounded rectangles label the ends of molecules (e.g. N, C, 5’, 3’) White rectangles label named nucleic acid molecules or sequence within a pair of dotted lines.  Circles label proteins.  Triangles label distinct structural features of double stranded DNA. What does each letter label?   Answers must be precise and complete to receive credit.

Which are the peptide bonds?  Select ALL for full credit. They are given in the following format:  “atom X to atom Y”. So if you think that there is a peptide bond between atom 1 and atom 2 (as labeled in the diagram above), you’d choose “1 to 2”.

The original DNA coding sequence is: 5′ AAG CTC GAC TCA AGG TAG 3’Original Protein: Lys – Leu – Asp – Ser – Arg – STOP The reading frame is fixed. For each row  in the table below, identify: what is the DNA mutation?  what is the effect on the protein?    For rows A-E, write your response below and use the following terms:DNA mutation: Substitution , Insertion, Deletion Effect on protein: Silent, Missense, Nonsense, Frameshift
