Answer:
target cell
Explanation:
Cell communication includes one or more signaling cells and the target cell. Signaling cells produce signals. In the case of chemical signaling, the signaling cells produce chemical signals such as hormones or neurotransmitters or ligands. Target cells are the cells that respond to a specific signal produced by the signaling cell.
To receive and respond towards the signal, the target cells produce receptors where the signaling molecules bind to produce the desired effects in the target cells. For instance, liver and muscle cells are one of the primary target cells for the pancreatic hormone insulin.
Answer:
B. a bowling ball
Explanation:
According to Newton's law of universal gravitation every body attracts another body by an amount of a force that is directly proportional to the product of the two bodies' masses and inversely proportional to the square of the distance between them. Knowing this then, it becomes clear that the body with the biggest mass will exert the greatest gravitational pull. From this list the ball with the biggest mass will be a bowling ball.
