The Milky Way galaxy is described as a disk of stars orbiting a central point on the disk. Which of these best explains why people on Earth cannot see the entire shape of the Milky Way? Many more stars exist outside of the galaxy Many more stars exist outside of the galaxy Earth is a part of this galaxy so the rest is not easily visible Earth is a part of this galaxy so the rest is not easily visible The stars in the center of the galaxy are extremely small The stars in the center of the galaxy are extremely small The center of the galaxy consists of a dense cluster of stars

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Explain how the integumentary system plays a crucial role in the ability to maintain homeoestasis

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.
