In 2004, tests were performed on the San Carlos Reservoir in Arizona to determine levels and distributions of some toxic metals.

Cores of sediment were sampled and tested, and the scientists found that there were two time periods represented in the sediment by larger levels of copper than is recommended in sediment quality guidelines. What scientific investigation might these results lead the scientists to next?

Answer:

an investigation on how copper affects aquatic life in the reservoir

Explanation:

It was observed that there were two time periods represented in the sediment by larger levels of copper than is recommended in sediment quality guidelines at the San Carlos Reservoir in Arizona

The next things that will be on their mind is to investigate on how copper affects aquatic life in the reservoir

What is an example of a stimulus and a response that humans exhibit? Can a similar behavior be seen in any other organisms?
Sedaia [141]
Common examples of this would be if you place your hand in extremely warm or cold water, and an immediate response of pulling out of the water or any fluid, is an example of this extreme response, other responses are what is done in everyday, like being thirsty or hungry etc.

These behaviours are shared by all organisms even the most simple ones.

Which part of the chemical equation is incorrect
ikadub [295]

The part of the chemical equation is incorrect is The solution is 10 02, it ought to de 1302.For carbon, on each aspects, there are eight carbon atoms.For hydrogen, on each aspects there are 20 hydrogen atoms.

<h3>What a part of a chemical equation are you able to by no means alternate?</h3>

When you stability an equation you could most effectively alternate the coefficients (the numbers in the front of molecules or atoms). Coefficients are the numbers in the front of the molecule. Subscripts are the smaller numbers observed after atoms. These can not be modified while balancing chemical equations.

The complete question is Which part of the chemical equation is incorrect which is 2C4H10+ 10O2 - 8CO2+10H2O.

  1. To realize if a response is properly balanced among the reactants and the products, you need to calculate the wide variety of atoms of every detail on each aspect of the response and to test if they may be equal.
  2. For oxygen, there are 20 oxygen atoms withinside the reagents and 26 withinside the products, so it's miles essential to grow the wide variety of oxygen withinside the reactants (with out touching the others). For this we positioned thirteen 02 withinside the reactants rather than 10, to have 26 oxygen atoms on every side.

Is ammonium hydroxide a reactant or product
KengaRu [80]

Explanation:

Ammonium hydroxide mostly acts as a reactant. Ammonium hydroxide is a colorless solution and exists only in solution form. It has a strong and pungent odor. It reacts with sulfuric acid and also many other strong acids. This reaction is exothermic which releases huge amount of heat or energy.

Ammonia water when in contact with volatile compounds, forms fumes. Ammonium hydroxide dissolves copper and zinc. It produces ammonia and nitroxides when heated to decomposition.

Which of the following are useful traits of cloning vectors?
SSSSS [86.1K]

Answer:

The correct answer is option - e. all of the above are useful traits.

Explanation:

A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -  

The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.

Thus, the correct answer is option - e. all of the above are useful traits.
