Animals cells have a mitochondria, plant cells have a vacuole, a chloroplast and a cell wall for protection.
Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
The organisms who do better at surviving and reproducing will pass on more genes than those who don't. So those with better adaptations will survive more to pass on those genes.
Answer:
solids are more tightly packed together (the molecules) than liquid or gas so it allows it to travel through vetter/faster
to digest food in order to get nutrients.
