The Ptolemy's theory of the solar system was disproved by the discovery of the new information. The Ptolemy's theory stated that the Earth is at the center of the solar system and all the planets, suns and stars orbited around it while the Earth stayed completely stationary. However, this theory was proven to be false as the sun-centeric model of the solar system better explained various phenomenon, such as the particular movement of the planets.
Hence, the correct answer is 'Ptolemy's theory of the solar system'.
Mendel crossed the dominant smooth seeded pea plant (SS) with the recessive wrinkled seeded pea plant (ss). The F 1 generation produced the heterozygous smooth seeded plants with a genotype Ss. When two heterozygous pea plants (Ss) are crossed in the F2 generation represented by Ss x Ss, the gametes formed are S and s. In the second generation, out of the total offspring produced, 3 have the smooth seeded phenotype and 1 has wrinkled seed phenotype. Thus the phenotypic ratio is 3: 1 with one out of four plants being a wrinkled seeded pea plant.
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
