The nursing assistant observes an area on the resident’s arm that is warm, red, and tender to touch. What is the appropriate response by the nursing assistant? 

Scenario 1 – “Muscle‑Twitch Mice” (10 Points) A colony of lab mice has begun displaying sudden, short bursts of running whenever a loud sound occurs. Researchers discover a dominant allele T that encodes a hyperactive epinephrine receptor in skeletal‑muscle cells.   Which change most directly explains the mice’s behavior? Hyper‑activity of this receptor would first increase the activity of which enzyme inside the muscle cell? To verify that the T allele produces a longer receptor protein, what step follows transcription of the T mRNA? If skeletal‑muscle cells alone express the epinephrine‑receptor gene, which explanation is most consistent? Researchers design primers flanking a 180 bp region that includes the T mutation. After PCR and agarose‑gel analysis they expect the mutant allele to show:

Scenario 4 – “The Silent Stem” (10 points) Botanists study a plant whose stem cells fail to divide unless exposed to light. Light activates transcription factor PHY‑A via a phosphorylation cascade. Adding a protein‑phosphatase inhibitor would likely PHY‑A target genes become euchromatic because If one target gene has two introns, its mature mRNA will be Scientists map a 3 kb PHY‑A enhancer using BamHI and HindIII. Restriction mapping is useful because it A partial Sanger chromatogram shows double peaks starting at one position. This likely indicates

If the heat produced by the reaction of combustion of 1 mole of ethanol (MMethanol= 46.07 g/mol) is 1366.8 kJ/mol, ((see the thermochemical equation below, the formula of ethanol is C2H6O), how much heat in kJ is produced by the combustion of 155 g of ethanol at the same conditions? C2H6O(g) + 3 O2(g)  → 2 CO2(g) + 3 H2O(g);       ∆H°rxn=−1366.8 kJ/mol

Use the special form of Hess’s law and given ∆H°f of the reactants and products to calculate the heat for the reaction (∆H°rxn)  of methane with oxygen:  CH4 (g) + 2 O2(g) CO2(g) + 2 H2O(l)   ∆H°f, methane (g) -74.60 kJ/mol ∆H°f, water (l) -285.8 kJ/mol ∆H°f, carbon dioxide (g) -393.5 kJ/mol  

Which type of cells carry the CD4 and CD25 proteins and suppress T cells against self?

Penicillin is a narrow-spectrum antibiotic known to kill Gram-positive bacteria by breaking down the Peptidoglycan layers of the Cell Wall.  Which structure in the common nucleus of the Penicillin is responsible for its mode of action?

A principle threaded throughout this book is

In precapitalist forms of commerce, where goods are bought in one place at a certain price and then sold at another site for a profit, the commodity has what economists call ______ value.

The ______ complex refers to the “confluence of public and private sector interests in the criminalization of undocumented migration, immigration law enforcement, and the promotion of ‘anti-illegal’ rhetoric”.
