Ocean acidification is of considerable concern to environmental scientists as it could impact ocean biodiversity significantly. What is the most likely chemical reaction that contributes to the change in ocean pH?
es ))
A)
Carbon dioxide interacts with ocean water to form carbonic acid, which
lowers ocean pH
B)
Nitrous oxide interacts with ocean water to form nitric acid, which
increases ocean pH.
C)
Decaying organic matter in the ocean releases acetic acid, which lowers
the oceanic pH.
D)
Sulfur dioxide interacts with atmospheric water vapor to form sulfuric acid
which falls into the oceans, lowering the pH.

Iron reacts with oxygen to produce iron oxide (rust). this reaction is represented in an equation as 4fe + xo2 → 2fe2o3. identify the value of x that will balance the equation.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.

Enzymes are proteins that speed up reactions by providing an additional energy source supplying additional molecules for the reaction removing inhibitors that slow down reactions lowering the amount of energy required
