A cell wall, because animal cells have a cell membrane, ribosomes are used to reproduce some proteins same goes for mitochondrias.
- It was a weakly reducing atmosphere
- It was hotter
Explanation:
The primordial earth’s atmosphere was mainly composed of carbon dioxide and methane. These are greenhouse gases that kept the temperatures of the atmosphere high because they trap infrared radiation that reflects off the earth's surface. These gases also made the atmosphere a reducing atmosphere due to the absence of oxygen. The most likely source of carbon dioxide was frequent volcanoes at the time and the methane from early anaerobic microbes.
The atmosphere changed when photosynthetic organisms evolved and caused the Great Oxygenation Event because they evolved oxygen.

Depends on the ingredients but i doubt they contain any meats <span />
Yes because just how the use lights to keep food warm a fast food places and such I have also used this in science to heat up pizza
If you want what it does it protects the cells from its surroundings, It's made of embedded proteins I believe. Hope that helped please answer my question.
