The sandstone arches found in arches national park, utah, are an example of Sedimentary rock. Sandstone is composed of cemented sand grains and is the cliff-forming rock commonly seen in southern Utah. Two famous formations are the Entrada Sandstone seen in Arches National Park, and the Navajo Sandstone (Checkerboard Mesa) in Zion National Park.
E. coli cells are found in the kingdom and domain of bacteria. They are unicellular, microorganisms that are single celled and shaped like rods
Answer:
Neurotransmitters are released from axon terminals via exocytosis
Explanation:
Dendrite is the receiving part of the presynaptic neuron, while axon is the transmitting part of the neuron. So, after initiation, action potentials travel down axons to the terminals. Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells (exocytosis of the vesicle's content). Neurotransmitter ACh (from the vesicles) binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.
