Question 11

frontal lobe

Answer 11

anterior portion of cerebral hemisphere
(controls muscles movements, speech (on left, Broca)) personality, intellect, complex learning, reasoning, abstract idea making)

Question 12

parietal lobe

Answer 12

between from and occipital lobe

• Somatic sensation
• General interpretation areas
• Language (left side; Wernicke’s area)

Question 13

Answer 13

lateral sides of cerebral cortex

• General interpretation areas
• Hearing

Question 14

occipital lobe

Answer 14

back of cerebral hemisphere (vision)

Question 15

Primary somatosensory cortex

Answer 15

In postcentral gyrus of parietal lobe Receives impulses from body’s sensory receptors (eg, pressure, pain, temperature)`

Question 16

primary motor area

Answer 16

In precentral gyrus of frontal lobe Conscious or voluntary movement of skeletal muscles`

Question 17

somatosensory association area

Answer 17

Immediately posterior to primary somatosensory area Interpretation of sensory impulses

Question 18

wernickes area

Answer 18

Left hemisphere at the junction between parietal and temporal lobes Language area: interpretation of speech by recognizing spoken words

Question 19

brocas area

Answer 19

Left side of frontal lobe in most people Motor speech area

Question 20

auditory areas

Answer 20

Temporal lobes at the junction with the parietal lobes Auditory sensory and interpretation areas

Question 21

vision areas

Answer 21

Occipital lobe Visual sensory and interpretation areas

Question 22

brain stem

Answer 22

a) midbrain: relay motor output from cerebrum to pons, medulla oblongata, spinal cord. relates sensory input from spinal cord to thalamus
coordinated movements of eyes, head, neck to auditory and visual stimuli
b)pons:
- Relays information from different brain areas to the cerebellum
- Together with the medulla oblongata, helps control breathing
D)medulla oblongata:
- Relays motor and sensory information between spinal cord and different brain areas
- Controls of consciousness and arousal
- Regulates breathing, cardiac functions, and blood vessel diameters

Question 27

Bacteria lab protocol

Answer 27

a) 250 microL of transformation solution into 2 microcentrofuge tubes (creates channels in cell wall and plasma membrane of bacteria so DNA can go in) they are competent cells when treated 2) put on ice and put 2-4 big coli colonies into tubes using a sterile loop and mix 3) add 0.8 x 10-1 μg/μL pGLO plasmid into one tube (using loop/10micro litter) 4) ice for 10 mins 5) put into 42 degree water bath for 50 sec then on ice for 2 mins 6) add 25μL of LB to both tubes then put at room temp 10 mins 7) put 100μL of solution on each labeled plate (+/- LB amp and +/-LB amp ara) spread using loops 8) stack and tape together upside down in 37 degrees for the night

amount of dna on +lb/amp/ara plate calculation

Answer 30

=volume of DNA put on/total sample volume | =100(PGLO) / 510 (PGLO+LB+transformation solu)
