Plant growers somtimes steralize their potting soil by heating it to high temperatures to kill pathogens that might be in the soil. how might the heat sterilazation of the soil affect the ammount of nirate available to tomato plants grown in that soil?
the amount would remain constant as air was in contact with the soil
there would be more nitrates because nothing was competing against them
the amount would slowly increase as the plants roots broke down the soil
there would be less nitrates since the nitrate producing bacteria were also killed

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
