Amy rolled a marble down a ramp and recorded the potential energy and kinetic energy of the marble at different positions on the ramp, as shown in the table below. marble experiment height of marble from ground (meters) potential energy of marble (joules) kinetic energy of marble (joules) total energy of marble (joules) trial 1 1 1 4 5 trial 2 2 4 1 5 which of these is the outcome (dependent variable) in this experiment? (3 points) mass of marble force of gravity potential energy of marble height of marble from ground

Hormones are chemical molecules produced by endocrine glands. one such endocrine gland is the thyroid gland, which synthesizes the thyroid hormone, which in turn affects the heart muscles. which two statements describe the probable reason for the function of the hormone? the cells in the heart have specific receptors that allow for the intake of hormones. the heart and the endocrine glands have the exact same types of cells. all cells make the same types of hormones. thyroid hormones show their effect on the heart by means of specialized cells. thyroid cells and cardiac cells have different dna.
