Describe what happens when an enzyme is placed in environments that have different pH levels or
temperatures than its regular environment.

If your just looking for the "why" then this is what i do know about it.

Explanation:

Changes in pH cause amino acids' component atoms and molecules to ionize. This can make an enzyme change shape. These shapes determine function, so changing the shape can impair the enzyme's function, preventing it from speeding up chemical reactions.

Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . Enzymes therefore work best at a particular temperature.

Hope this helps.

the answer is d (apex) good luck : ))

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.

can i get the brainliest pls
