Michael, a researcher in the field of neuroscience, has a theory about a specific area of the brain causing difficulties in face recognition. to draw a solid causal inference, he intends to test his hypothesis on dogs by disrupting regions of their brains and examining the effects of this disruption on the dogs’ face-recognition capacity. which of the following techniques should be used by michael to achieve his purpose? a. transcranial magnetic stimulation (tms)b. computarized axial tomography (cat scan)c. functional magnetic resonance imaging (fmri)d. magnetic resonance imaging (mri)

Explain why methicillin resistant staphlococcus aureus (mrsa) is more prevalent now than it was only 30 years ago. a. antibiotics cause mutations in staphlococcus aureus that lead to an increase in the number of methicillin-resistant strains. b. methicillin resistance causes an infection to spread more rapidly.c. frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of staphlococcus aureus.d. diseases like aids have made people more vulnerable to infections from staphlococcus aureus.
