(01.03 MC Complete this sentence. If mass remains the same while the volume of a substancethe density of the substance will . O decreases, decrease O increases, decrease increases, stay the same O decreases, stay the same​

If mass remains the same while the volume of a substance increases, the density of the substance will decrease. The increase in the volume is called expansion, while the decrease in the volume is called contraction.

The density measures how much matter (mass) there is in a given amount of space (volume).  So, if the mass stays the same and the volume increases then there is the same amount of mass ad before but in bigger volume so the density is decreased.

Explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
