Answer: Higher concentration; Lower concentration.
Explanation: The food that we eat undergoes digestion and breaks down into smaller components.
These small components of the food needs to be absorbed first by the process of diffusion.
The water molecules along with the electrolytes are absorbed from an area of its higher concentration in the lumen is transported to area where its concentration is very low.
Hence, the correct answer is diffusion, which is responsible for the transportation of products from one place (higher concentration) to another parts (lower concentration)in the body.
Answer:
Humans participate in 1 and 3, so the answer is C. We burn fossil fuels and use our respiratory system to produce carbon. We do not, however, go through photosynthesis like plants.
Catalyst maybe ( lower activation energy).
