Answer:
A substance that removes carbon dioxide gas
Explanation:
Options-
A. A substance that removes carbon dioxide gas
B. A plant to produce oxygen
C. A glucose reserve
D. A valve to release excess water
Solution -
It is given that the rate at which oxygen is consumed and the rate at which carbon dioxide is produced is same. Therefore, if we somehow are able to measure the volume of carbon dioxide, we can interpolate the rate of consumption of oxygen from it.
Hence, A substance that removes carbon dioxide gas is essential to provide accurate volumetric measurements of oxygen gas consumption

<span>The speed of sound change as the sound of a boat engine moves down to the depths of the ocean The speed increases and then decreases as the temperature of the water increase. Sound do not travel faster in water than air due to the resistance. The salt and water molecules of the ocean cause interference for the sound wave to travel across it. It it had travel through air, then you can hear the sound of the incoming boat. But if it goes down into the water, and as you know it, going deeper into the water increases the pressure all the more that it muffles the sound of the engine of a boat. That is why it increases then decreases its sound as it goes down the ocean.
