Answer:
D. Lactose is absorbed intact and transported through the portal vein to the liver.
Explanation:
Lactose is a disaccharide. It is a sugar composed of galactose and glucose subunits and has the molecular formula C₁₂H₂₂O₁₁. Lactose as a disaccharide can never be absorbed just like that. It needs to be broken down into monosaccharides first.
Answer:
roots spread out underground like the branches of a tree as to get sufficient water and nutrients form the soil to transport to the other parts of the tree for its own growth , by spreading out roots tend to collect or suck the maximum nutrients
Answer:
Cell wall, chloroplast, and central vacuole
Explanation:
Cell wall, chloroplast, and central vacuole are present in a plant cell but not in the animal cell.
Nucleus, cell membrane, and cytoplasm present in both plant and animal cells.
Answer:
- In terrestrial environments: increasing CO2 levels cause an increased photosynthetic rate
- In aquatic environments: increasing CO2 levels cause an increase in water acidity
- In both terrestrial and aquatic environments: increasing CO2 levels lead to an overall increase in the average temperature (global warming)
Explanation:
In terrestrial ecosystems, rising carbon dioxide (CO2) levels increase the rate of photosynthesis (since CO2 is one of the reactants in photosynthesis), thereby also increasing plant growth. Moreover, in aquatic ecosystems, rising CO2 concentrations increase the levels of this gas dissolved on the surface of the oceans. This increases the acidity of the oceans, thereby modifying habitats and food web structures. The increasing acidity of the oceans also reduces the amounts of carbonate, which difficult for aquatic species (e.g., corals) to form their shells/skeletons. Finally, CO2 is a greenhouse gas that contributes to the increase in the average temperature by absorbing solar radiation that would otherwise have been reflected by the Earth's surface, and this increase in the temperature negatively affects life in both terrestrial and aquatic environments.
