Afish is removed from a contaminated lake. you determine that a particular toxin (x) is present in its cells at concentration x = 1,500 μg/l. you place the fish in a tank full of clean water (x = 0 μg/l), and measure the toxin concentration in the fish cells each day for the next 10 days.

after making your hypothesis, you test it by measuring the toxin levels in the fish at various times during its 10 days in the tank. you observe that the level of toxin in the fish drops from 1,500 μg/l to 750 μg/l and then stabilizes at 750 μg/l. you test the water in the tank and find that after it stabilizes, toxin is present in the water at concentration 750 μg/l also. what can you do to continue to reduce the toxin level in the fish below 750 μg/l?

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

What is the percentage composition of carbon in the compound ch4

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
