Correct answer: D). Contradicted the accepted belief in spontaneous generation
Rudolf Virchow's and Louis Pasteur's contradicted the theory of spontaneous generation, which state that living organism originates from non-living matter.
According to this theory, it was believed that dust creates fleas, maggot arises from the rotten meat, wheat and bread left in the dark corner produces mice.
Louis Pasteur was the first scientist to prove that cells originate from the pre-existing cells.
Rudolf Virchow proposed that Omnis cellula e cellula, which means each cell comes from another cell.
Answer:
A. About 10%
Explanation:
The percentages of cells in each population represent the percent of the cell cycle a given cell spends in each phase, so it spends about 10-20% of its time in mitosis and 80-90% in interphase.
Answer:
The correct answer is homologous.
Explanation:
A structure that is derived from a common ancestor is called homologous structure. So homologous structure is the characteristic of divergent evolution that means divergent evolution give rise to homologous structures.
So as the marsupials are mammals that were diverged from placental mammals very early in mammalian evolution, the membranes of skin that allow Australian sugar gliders and North American flying squirrels to glide are homologous because divergent evolution gives rise to homologous structures.
The function of these homologous structures can be the same or can be different. Therefore the correct answer is their membrane are homologous.
