What are two ways nonliving things could affect
yellow-rumped warblers?

the nonliving things that could affect  yellow-rumped warblers is the temperature and humidity of the atmosphere.

Explanation:

Yellow-rumped warblers is a type of bird which is found in central and North  America. Temperature and humidity has a great impact on yellow-rumped warblers. They migrate to central america when the winter season arrived because the climate of central and north america is warm and wet due to more rainfall. This bird does not tolerate the extreme low and high temperature so that's why they migrate to warm areas in the winter.

I believe the response would be D. Increasing the pH within the cell. This may be the case, because through changing the pH of the cell, the enzyme may form new unwanted interactions, which may affect the arrangement and the structure of the active site, which is will affect the ability of the maltose molecules to bind and undergo the breakdown into glucose molecules.

All enzymes work well or optimally within a given or particular pH. Going above or below will cause additional hydrogen bonds that might form, and other interactions affecting function.
