These scratches and gouges are usually created by a moving glacier, another term would be glacial abrasion. Scratches were formed when boulders and gravel get trapped under the ice. These are best seen after rain and through a low-angle light.

Answer:

These scratches and gouges are usually created by a moving glacier; another term would be glacial abrasion. Scratches were formed when boulders and gravel get trapped under the ice. These are best seen after rain and through a low-angle light. Glacial grooves and striations are gouged or scratched into the bedrock as the glacier moves downstream. Boulders and coarse gravel get trapped under the glacial ice and abrade the land as the glacier pushes and pulls them along.<span>

Under normal conditions, what would be the PRIMARY mechanism that his body would use to reduce the amount of PCO2 in the blood
sergeinik [125]

The pH of blood if pco2 drops to 35.0 mmHg is 7.459

The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.

pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )

pK is 6.1 for the bicarbonate buffer system.

HCO3- = 24mm

PCO2  = 35.0 mmhg

pH = 6.1 + log ( 24 / 0.03 * 35.0 )

    = 6.1 + log ( 24 / 1.05 )

    = 6.1 + log 22.8571

    = 6.1 + 1.3590

    = 7.459

Hence, the pH of blood is 7.459
