Answer:
of diffusion
Explanation:
Particles travel along a concentration gradient without requiring energy. This indicates they transition from an area of high concentration to one of low concentration. This process takes place across a semi-permeable membrane, such as the cell membrane, via simple diffusion.
In the situation outlined, the key step is to evaluate and ensure proper ventilation. A lack of oxygen can cause the heart rate to drop due to insufficient oxygen supply to the heart, making effective lung ventilation the most critical action in this context.
The endosymbiotic theory provides an explanation for the evolution of chloroplasts and mitochondria within eukaryotic cells.
This hypothesis posits that eukaryotes developed through a mechanism in which different types of free-living prokaryotes were absorbed into larger prokaryotic cells, eventually transforming into chloroplasts, mitochondria, and other organelles.
Answer:
B
Explanation:
Cellular respiration relies on glucose and oxygen to generate carbon dioxide and water.... Plants and other organisms perform photosynthesis to create energy, while cellular respiration processes energy for utilization.
