All food, but fruit is my favorite.
Answer:
prokaryotes and eukaryotes both have ribosomes
Explanation:
because both have ribosomes but those ribosomes are not the same kind
Answer:
The answer to your question is below
Explanation:
1.- Prophase
2.- Metaphase
3.- A
4.- centrosomes
5.- Interphase
6.- D, A, C, F, E, B
7.- Animal cells, because plant cells have a cell wall that is a rigid structure that can be divided but gives support to the plant cell and in this picture, the cells do not this structure.
8.- Interphase
9.- Because cells can reproduce and newborn cells replace the old ones.
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.
