For questions 1 and 2 use this diagram of the cell where one of the mitochondria has been enlarged.
From the information in the passage and the diagram, what can
you conclude about the structure of mitochondria?
They are organelles, which are a group of flattened
membrane sacs stacked on top of each other.
They take instructions from DNA and make proteins.
They are membrane-bound organelles with a second,
folded membrane inside to provide extra area for cellular
respiration
They break down sugars to provide energy for the cell.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
