Tidal volume is air a. inhaled after normal inspiration b. remaining in the lungs after forced expiration c. forcibly expelled after normal expiration d. exchanged during normal breathing

a

Explanation:

Tidal volume (TV) is the volume of oxygen that enters the lungs (inspiration) through normal breathing. It is measured per kg of body mass.

It is also measurement applied by a ventilator machine. The machine delivers oxygen and the amount delivered is calculated as tidal volume.

'Remaining in the lungs after forced expiration' is called Inspiratory Reserve Volume (IRV)

'Forcibly expelled after normal expiration' is called Expiratory Reserve Volume (ERV)

D : exchanged during normal breathing

Explanation:

just answered on mastering A&P

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
