Give three characteristics of a uterine prolapse in cattle (including appearance, when it occurs, and is it an emergency).  

A balling gun can be used to administer:

Dairy cattle lameness is influenced by:

Predict the oxide below that would exhibit the most basic character in aqueous solution.       

For the reaction 2 H2(g) + O2(g)

Calculate the enthalpy change for the reaction, NO(g)  +  O(g)  →  NO2(g) from the following data: NO(g) +  O3(g)  → NO2(g)  +  O2(g)     ΔH = –198.9 kJ                 O3(g)   →  1.5 O2(g)                ΔH = –142.3 kJ                O2(g)   →    2 O(g)                   ΔH =  495.0 kJ

Them image below shows a protein purification using affinity chromatography. 1) What kind of resin is most likely of being used in this image? 2) Explain what is happening in steps 2, 3, and 4.

  Three different PCR reactions using a primer set with a perfect Tm of 50 C were performed. The expected product of each PCR was 1000 bp. The products obtained in each separate reaction were analyzed by electrophoresis. The results observed in the gel are depicted in the Figure. Which of the thermocycler programs described below was more likely used to obtain the results observed in Line 2; Line 3 and Line 4. The line 1 correspond to the molecular weight marker.  

E. coli transformation: Why do the cells, after transformation with the plasmid, need to be incubated for 45 min to 60 minutes in SOB/SOC or LB media without antibiotics?

After completing all experiments proposed in the advanced microbiology lab, you have now gained the ability to clone a gene using competent cells and express/purify proteins. List all steps involved in the cloning of alpha amylase from Bacillus subtilis using DH5 alpha and BL21 competent cell, including protein purification (just one sentence per step).
