Acharacteristic of acids is that they react with metals to: form non-metals release water release hydrogen gas produce bases

When an acid reacts with a metal it results in the formation of salt and hydrogen gas is liberated. For example, the nitric acid reacts with the calcium it forms salts of calcium nitrate and hydrogen gas is liberated.

c. genetic engineering

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
