Answer:
1. Signaling molecule
2. Signaling receptors
Explanation:
Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.
For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.
Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.
Growth, repair, reproduce
Answer:
Heart rate goes up, breathing gets labored
Explanation: heart using more blood to work, and then the heart needs more oxygen to work so it forces u to breathe more
Hope this helped!
Is composed of G1 phase<span> (</span>cell<span> growth), followed by S </span>phase<span> (DNA synthesis), followed by G2 </span>phase<span> (</span>cell<span> growth). At the end of interphase comes the mitotic </span>phase<span>, which is made up of mitosis and cytokinesis and leads to the formation of two daughter </span>cells<span>.
