During archaeological excavations near the Dead Sea, seeds of Phoenix dactylifera, the species of palm tree that produces dates, were discovered. Some of these seeds were reported to be around 2000 years old and still viable, meaning they had the potential to germinate and grow into new plants. This discovery was significant as it provided insights into the longevity and resilience of seeds, as well as the ancient agricultural practices in the region. Therefore, the correct answer is (C) Phoenix dactylifera (date palm).
The correct answer is:
Option 3: Phoenix dactylifera
The viable seed discovered during the archaeological excavation near King Herod's palace, near the Dead Sea, was of the plant Phoenix dactylifera, commonly known as the date palm. The seed, which was over 2000 years old, was successfully germinated, making it one of the oldest seeds to ever sprout.
Phoenix dactylifera (date palm) is known for its historical and cultural significance in the Middle East.
The other options are incorrect because:
Lupin (Option 1) and sunflower (Option 2) are not the seeds found in this excavation.
Maize (Option 4) is a relatively new crop compared to date palms, and it was not found in this context.
Thus, the seed discovered in the excavation near the Dead Sea was from Phoenix dactylifera.
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
In an experiment to determine the figure of merit of a galvanometer by half deflection method, a student constructed the following circuit. He applied a resistance of \( 520 \, \Omega \) in \( R \). When \( K_1 \) is closed and \( K_2 \) is open, the deflection observed in the galvanometer is 20 div. When \( K_1 \) is also closed and a resistance of \( 90 \, \Omega \) is removed in \( S \), the deflection becomes 13 div. The resistance of galvanometer is nearly:
