I believe that the answer to this question is energy!! because cells need energy and the reason they respire is for energy
Answer:
Option D = 3.4 g/mL
Explanation:
Given data:
Volume of water = 21.2 mL
Volume of water + object = 27.8 mL
Mass of object = 22.4 g
Density of object = ?
Solution:
First of all we will calculate the volume of object.
Volume of object = Volume of water+ object - volume of water
Volume of object = 27.8 mL - 21.2 mL
Volume of object = 6.6 mL
Density of object:
d = m/v
d = 22.4 g/ 6.6 mL
d = 3.4 g/mL
If Green house gases continue to rise, their amount of heat trap will also continue & our Planet would become hotter & hotter which can lead to very dangerous situation for us.
Hope this helps!
