question:
Process:  -Solution caves are formed in limestone and similar rocks by the action of water -After a rain, water seeps into cracks and pores of soil and rock -The water percolates beneath the land surface -Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water -Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation -The water combines chemically with the carbon dioxide -A weak carbonic acid solution is formed -This acid slowly dissolves calcite, forms solution cavities, and excavates passageways -
 Question: What is the effect of less conservation occurs on less carbolic acid occurs.?
answer:
against


question:
Process:  -Air enters the nose or mouth and travels through the windpipe into the lungs -The lungs have a series of smaller and finer tubes and sacs -Air reaches the smallest and finest air sacs called alveoli -Oxygen travels from the alveoli into the blood -Oxygen-rich blood is carried to the heart -Oxygen-rich blood is pumped throughout the body by the heart -Cells take in the oxygen rich blood and release carbon dioxide rich blood -The carbon dioxide rich blood travels to the lungs -Carbon dioxide travels through the throat and is exhaled.
 Question: What is the effect of resting or sleeping on a greater amount of oxygen being delivered to the blood stream.?
answer:

against
