Cell-to-cell communication is particularly important in regulating gene expression during the embryonic development.
Cells in the developing embryo are constantly communicating with their neighbors. The molecules used by them in sending and receiving signals are crucial for normal embryogenesis. Various intracellular signaling pathways have been discovered, some of which are activated in response to secreted growth factors.
However, a few important signaling pathways are used often during embryonic development to regulate various cellular processes that shape the developing embryo.
Embryonic development is marked by the thorough regulation of cellular functioning so that the cells proliferate, migrate, differentiate, and form tissues at the correct place and time. These processes are genetically controlled and depend both on the history of cells, their lineage, as well as on the activities of signaling pathways, which coordinate the cell interactions leading to organogenesis.

Answer: How does taxonomy help us understand relationships among organisms on Earth? Taxonomy is about classifying organisms into related groups, and drawing up trees of common descent, from the shared ancestors from which the branches separated
Explanation:
Answer: Water waves are surface waters. Waved are created by energy that is passing through water particles. As the wave crest move, it causes water particles to move in a circular motion. Water don't travel in waves, waves energy trigger water movement which is driven by wind, this create friction between the wind and the water. The waves passes through the water but water particles remain in their formal position.
Explanation:
Water waves are surface waves in that they travel in circular direction due to energy created by the wave.
Answer:
A machine can decrease either the input force or the input distance needed to do a given amount of work.
