To conduct water and minerals to the leaves
The correct answer is: Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.
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. Neurotransmitter ACh 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.
Answer:
En la sucesión primaria la roca recién formada o recién expuesta es colonizada por primera vez por seres vivos.
En la sucesión secundaria, un área anteriormente ocupada por seres vivos se ve alterada o afectada, y luego se vuelve a colonizar después de la perturbación.
Explanation:
Answer:
The correct answer is - cytoplasm of the cell.
Explanation:
Cellular respiration is the bunch of metabolic reactions that convert biochemical energy from the glucose or other nutrients into ATP ( adenosine triphosphate) and releases water and carbon dioxide as waste products.
This process has three stages and the very first stage is glycolysis which is taking place in the cytoplasm of the cell. In this stage, the glucose molecule converts into the two molecules of pyruvate and produce energy.
Thus, the correct answer is - cytoplasm of the cell.
