Answer:
This is Because they can't be 100% in location of PCBs since animals could spread and reproduce among different places with these toxins within their systems.
Explanation:
Answer:
it tells us that it is the change in the characteristics of a species over several generations and relies on the process of natural selection
Explanation:
Natural Selection: The process where organisms have better adapted to their environment and tend to survive and produce more offspring than those without the adaptations
With that dictionary definition we know that we develop certain characteristics in order for survival. The characteristics are developed over multiple generations. One example is that we have a part of our body that we needed before, but no longer need as we don't need to be immune to poisonous foods (or that's what our body tells us)
<em>Answer:</em>
<em>The best answer to the question that is being given above would be letter A. The most complex level of organization hierarchy that climate change could potentially affect is Earth's Biosphere - which holds every living thing in the planet. This climate change will destroy it more destruction to Mother Nature occurs.</em>

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.
