I am not good at bio aka life so i need help with 19 and 20

#19 = The cell is an animal cell because it's missing the organelles required in plant cells(chloroplast, vacuoles, and the cell wall)

#20 = The mitochondria would be most likely to be affected because it's the powerhouse of the cell, provides energy, and imports proteins. I hope this helps.

Explanation:

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
