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:
One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.
Explanation:
- Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
- The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
- A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
- Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.
Answer:
