The correct Answer is:
To solve the question regarding who proposed the presence of a single supercontinent on Earth around 250 million years ago, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks which scientist proposed the idea of a single supercontinent existing on Earth approximately 250 million years ago. 2. **Analyze the Options**: - (a) Huxley: Known for his work in evolutionary biology but not related to the concept of supercontinents. - (b) Wegener: Proposed the theory of continental drift and the existence of a supercontinent called Pangaea. - (c) Wilson: Known for plate tectonics but did not specifically propose the concept of a supercontinent existing 250 million years ago. - (d) Libby: Known for his work in radiocarbon dating, not related to supercontinents. 3. **Identify the Correct Answer**: Based on the analysis, Wegener is the scientist who proposed the existence of a supercontinent (Pangaea) that existed around 250 million years ago. 4. **Conclusion**: The correct answer is (b) Wegener. ### Final Answer: (b) Wegener ---

Some questions (Assertion-Reason Type) are given below. Each question contains Statement I (Assertion) and statement II(reason). Each question has 4 choices (a),(b),(c ) and (d) out of which only one is correct. So select the correct choise. a. Statement I is True, Statement II is True,Statement II is a correct explanation for Statement I b. Statement I is True, Statement II is True, Statement II is NOT a correct ecplanation for Statement I c. Statement I is True, Statement II is False . d. Statement I is false, Statement II is True. Statement:I Though light of a single frequency (monochromatic light) is incident on a metal, the energies of emitted photoelectrons are different. Statement II: The energy of electrons just after they absorb photons incident on the metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

In 1894 , Lord Rayleigh reported that the mass of chemically prepared nitrogen was different from that of nitrogen extracted from the atmosphere, as shown in Tables 1 and 2 . Latter, this difference was attributed to the presence of argon in atmospheric nitrogen. The masses of gases were mearsured by using a glass vessel with a known volume under atmospheric pressure (1.013xx10^(5)Pa) . |{:("From nitric oxide",,2.3001 g),("From nitrous oxide",,2.2990 g),("From amonium nitrite purified at a red heat",,2.2987 g),("From urea",,2.2985 g),("From ammonium nitrite purified in the cold",,2.2987 g),("Mean",,2.2990 g):}| |{:(O_(2) "was removed by hot copper" (1892),,2.3103 g),(O_(2) "was removed by hot iron" (1893),,2.3100 g),(O_(2) "was removed by ferrous hydrate (1894),2.3102 g,),(Mean,,2.3102 g):}| Ramsay and cleve discovered helium in cleveite (a mineral consiting of uranium oxide and oxides of lead, thorium, and rare earths, an impure variety of uraninite) independently and virtually simultaneously in 1895 .
