1. Skeletal modifications that assist with avian bipedal locomotion include:

A. uncinate process

B. expanded ilium

C. pygostyle

D. carina

Expert Solution

bipedalism: moving on two legs which includes walking , running, hopping, jumping and skipping gaits.

all birds are bipedal, it is a feature inherited by the dinosaur ancestors.

uncinate process: extending from midpoint of the vertebral ribs, integral to mechanics of ventilation in birds, active in both inspiration and expiration. Also play role in locomotion. They have also occured in the theropod dinosaurs, proving that they are the ancestors of the birds.

pygostyle: final few caudal vertebrae fused into single ossification supporting the tail feathers and musculature. composed of several fused caudal vertebrae supports the retricial bulb and associated muscles and feathers for controlling tail fan and contour shape.

carina : also known as KEEL is a bird anatomy which is the extension of sternum (breastbone) running axially along the midline of the sternum while extending outward , perpendicular to the palne of ribs. one of the most obvious and important modification in the avain skeleton.

therefore the choices are : A, C, D

1. Dunder Mifflin recently expanded its supply to include not just paper, but also copiers. David Wallace, the chief financial officer, claims that the expansion is a smashing success, with the copier production process producing defective parts only 0.7% of the time. Michael Scott is not superstitious. . . but he is a little stitious. He believes that David Wallace’s claim is incorrect. He randomly selects 750 copier parts and finds 12 that are defective. Do these data provide evidence...

1. Dunder Mifflin recently expanded its supply to include not just paper, but also copiers (much to Pam’s delight). The expansion was a smashing success, with the copier production process producing defective parts only 0.8% of the time during the first year. Michael Scott believes that updates to the production technology have improved this process. He randomly selects 1000 parts and finds 6 defective parts. Do these data provide evidence at the 5% level that the process has improved? (a)...
