Answer:
Prokaryotic cell:
Prokaryotic cell do not have the nucleus and their DNA is present in the cytoplasm. The membrane bound cell organelle are absent in the prokaryotic cells. The ribosome of prokaryotic cell is 70'S. Transcription and translation is coupled in prokaryotic cells.
Eukaryotic cells:
Eukaryotic cell have well defined nucleus and their DNA is present inside the nucleus. The membrane bound cell organelle are present in the eukaryotic cells. The ribosome of eukaryotic cell is 80'S. Transcription and translation is not coupled and takes place in separate compartments in eukaryotic cells.
Answer: D. Galaxies show a red shift, indicating they are moving away from each other.
Explanation:
Galaxies seem to show a red shift which indicates that the galaxies are moving away from each other. This provides evidence for the Big Bang theory because the theory posits galaxies will keep moving away from each other.
This is because when an explosion happens, matter moves away from the point where the explosion happened. If the Big Bang happened therefore, galaxies will move away from the source which is why galaxies are moving away from each other.
Para poder probar que la generacion espontanea despues de hervir el agua no es posible ya que en ese tiempo esa era la teoria aceptada por todos.
Anteriormente alguien habia hecho el mismo experimento tapando el frasco con un corcho, ese experimento despues de ser hervida el agua produjo seres nuevos (microorganismo) y Pasteur hirvio el agua solo para provar que los microorganismo no se podian generar magicamente despues de ser hervidos
