Which statements best describe shared characteristics? Select two options. Shared characteristics always exist in the common ancestor and in the modern organism.
Shared characteristics never exist in the common ancestor or in the modern organism.
The more characteristics organisms share, the more closely related they are.
The fewer characteristics organisms share, the more closely related they are.
Shared characteristics can exist among organisms that belong to different species.
Shared characteristics only exist among organisms that belong to the same species

In which of these cases are the two wave points considered to be in phase with each other?

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.
