the cells that make up multicellular organims send, receive, and respond to a variety of signals. which statement is an example of direct signaling?

Respuesta :

Only signaling molecules which are intended for a given cell can cause a response. Because long-range signaling molecules cause a cell to react.

Growth factors, hormones, neurotransmitters, or extracellular matrix elements are only a few of the numerous chemical signals that cells in multicellular organisms use. Multicellular organisms use four different types of chemical signaling to communicate with one another: paracrine, autocrine, endocrine, and direct touch. The process through which a cell gets a signal, any intracellular adjustments that result from signal reception, and the manner in which the cell modifies its behavior are all referred to as signal transduction. For multicellular creatures to develop, operate, and survive in their infancy, signal transduction is essential. Cell signaling enables the specialization of cell groups in multicellular organisms. Because long-range signaling molecules cause a cell to react. Then, different cell types can combine to produce tissues like muscle, blood, or brain tissue. A stimuli is a signal that an organism responds to.
