Answer:
Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.
Explanation:
Answer: Hydroelectric power is a renewable resource that doesn't rely on the whether.
Explanation: Solar power and wind power are also renewable resources but they both rely on whether. Wind power can't work without wind, and solar power can't produce as much energy on stormy or overcast days.
Answer:
Option D
Explanation:
It is given that the permeable membrane at the base of the tube is permeable to NaCl solution but is not permeable to glucose.
Thus, sodium chloride from the arm of tube with high NaCl concentration will start moving towards the arm with low NaCl concentration and hence, the salt concentration will reduce on side A.
The volume will not remain constant as the concentration of NaCl on side A will reduce thereby decreasing the water level from its initial mark
Hence, option D is correct
