Answer:
A.
Explanation: Maria did not measure the solutions' densities before mixing the solutions.
change in temperature and pH can change the shape of the enzyme and They can break down the reactants
Temperature. Higher temperatures typically result in faster rates of reaction, whether they are enzyme-catalyzed or not. The chemical bonds in the active site, however, can be impacted by temperature changes that are either too high or too low and make them less able to bind substrates. Extremely high temperatures (over 40 degrees Celsius may cause animal enzymes to denature, losing their form and activity)
pH can also affect enzyme function. The acidic or basic characteristics of active site amino acid residues are frequently crucial for catalysis. These residues can be impacted by pH changes, which can make it difficult for substrates to bind. Like with temperature, certain pH ranges (acidic or basic) can cause enzymes to denature. Enzymes function best within these pH ranges.

Species are going extinct before we know it because species are constantly adapting to their environment leading them to then evolve with different traits more suitable for their environment, thus creating species out of the ones that previously existed.
<span>On the Galapagos Islands, Darwin notice several types of finches that varied from island to island, where each finch species had different kinds of beak depending on the available food on the area. That discovery helped him to develop his theory of natural selection where he concluded that<span> as the finches are adapting to their new environments and food sources, they gradually evolved into different species.</span></span>
