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

Explanation:
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination
Invertebrates have no spine, and they often don't have nearly as many organs as vertebrates. Overall, they are much simpler organisms.
Answer:
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration.
Explanation:
Chloroplast converts solar energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell, produces ATP- the energy currency of the cell during respiration.
