Question

what paper can be used to test ph?
filter
litmus
computer
microscopy
buffers are necessary to help organisms maintain
flexibility
heat capacity
homeostasis
adhesion

Explanation:

• First question: Litmus paper changes color depending on the pH of a solution (red for acidic, blue for basic). Filter paper is for separating solids from liquids, computer paper is for printing, and microscopy is a technique (not paper).
• Second question: Buffers resist pH changes. Homeostasis is the maintenance of a stable internal environment (including pH balance). Flexibility is about physical bendability, heat capacity relates to heat - holding ability, and adhesion is the attraction between different substances.

Answer:

1. B. litmus
2. C. homeostasis
