A fish 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?

The level of toxins in the fish's cell is equivalent to the level of toxins in the water. Therefore, in order to reduce the toxins further, we should replace the now contaminated water with clean water. After the level of toxins in the fish's cell stops reducing, we replace the water with clean water once again.

What are the steps used to write ionic formulas for ionic compounds
lorasvet [3.4K]
Write the symbols for the cation and the anion: Mg and Cl. Determine the charge on the cation and anion. If the cation has a Roman numeral after it, that is the charge on that cation. Cations receive Roman numerals when they can take more than one ionicform.

Based on the passage, what is the structure of the product of the reaction between 8-hydroxyquinoline-5 sulfonate and hrp?.
Mashutka [201]

A because the end result of this reaction is a radical created by the oxidation of an aromatic amine's or phenol's ring substituent. The hydroxyl group of a phenol acts as the ring substituent in this situation.

<h3>Which two enzyme types are required for the two-step process of converting cytosine to 5 hmC?</h3>
  • The methyl group is transferred to cytosine in the first stage, and it is then hydroxylated in the second step.
  • Therefore, a transferase and an oxidoreductase are the two groups of enzymes required.

<h3>Which kind of interaction between proteins and the dextran column material is most likely to take place?</h3>
  • Hydrogen bonding because the glucose's OH would form an H-bond with any exposed polar side chains on a protein surface.

<h3>Two out of the four proteins would adhere to a cation-exchange column at what buffer pH? </h3>
  • Only positively charged proteins can bind to a cation-exchange column, and this can only happen when the pH is lower than the pI.
  • Proteins A and B would both be positively charged at pH 7.0.

Which process maintains homeostasis by replacing cells that die or get damaged? A. Cell division B. Cell respiration C. Exceptio
aleksandr82 [10.1K]

Answer:

Cell division

Explanation:

  • Cell division helps maintain homeostasis in living things since it creates new cells which can be used for growth and repair.
  • <em><u>Cell division occurs into two types, meiosis and mitosis . During mitosis, the cell creates two identical daughter cells that are identical to the parent cell, in terms of the number of chromosomes.</u></em>
  • These new cells are necessary to replace old cells that die in the organism, or to repair damage to the body.
