Fоr eаch оf the fоllowing sentences, fill in the blаnks with the best word or phrаse selected from the list. Cells can signal to each other in various ways. The [1] methods of cell signaling do not require the release of a secreted molecule and are used for very localized signaling events. During [2] signaling, the signal released remains in the neighborhood of the secreting cell and thus acts as a local mediator on nearby cells. An example of a signal molecule that acts locally is [3]. Insulin is delivered via [4] signaling. Signaling that involves new protein synthesis is [5] than signaling that requires the modification of existing proteins.

Fоr eаch оf the fоllowing sentences, fill in the blаnks with the best word or phrаse selected from the list. Microtubules are formed from tubulin [1]. Tubulin subunits are stacked together into protofilaments; thirteen parallel protofilaments form the [2] structure of a microtubule. Therefore the structures of the two ends of the microtubule are [3]. [4] ring complexes are important for microtubule nucleation and are concentrated in the [5]. A microtubule that is quickly growing will have a string of [6] tubulins that helps prevent the loss of subunits from its growing end. The motor protein [7] generates the bending motion in cilia.
