Explain your reasoning for distributing the pints of
blood the way that you did.

There is no O– blood, so Patient 1 can only receive the B– pint.

There is no O– blood, so Patient 4 can only receive the O+ pint.

The only remaining blood is B– and AB–.

Patient 2 can only receive the AB– pint.

Patient 3 can only receive the A+ pint.

Explanation:

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
