Answer:
The nucleus
Explanation:
This organelle gives all the info. Without it, the cell will die. It's like a human is alive without a brain.
Answer:
hippocampal place
Explanation:
A type of cell that fires when rats are in a specific location as opposed to some other locations are known as place cells.
Generally, place cells are specially shaped neurons whose origin is the hippocampus. These neurons fire or become more active when animals are in certain locations in its environment, as opposed to their overall environment.
The cells are from regions CA1 and CA3 of the hippocampus and collectively act as a cognitive representation of these locations where they are limited to firing. The locations where the neurons are limited to firing are referred to as place fields.
Hence,<u> the cells found in the rat as shown by the illustration are referred to as the place cells whose origin is the hippocampus.</u>
Explanation:
The main activity that occurs at the transmissive segment is the release of neurotransmitter from synaptic vesicles . Prior to the arrival of the action potential, Ca2+ pumps embedded in the plasma membrane of a synaptic knob establish a calcium concentration gradient by pumping it out to the IF. Consequently, there is more calcium inside of the synaptic knob than outside it.
Further Explanation:
At synaptic junctions:
- The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing Ca2+ to rush into the terminal due to higher extracellular concentrations
- these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters
- this leads to changes in the proteins leading to the fusion with the membrane of the presynaptic cell, so vesicles are open and neurotransmitter is released. The neurotransmitter diffuses across to chemical receptors on the presynaptic cell where they bind temporarily
- This leads to activation of specific complexes, enabling the transmission of information. Thus, the chemical signal is transferred through this neuron as an electrical impulse

Answer:
Tropic of Cancer marks the northern edge. Tropic of Capricorn marks the southern edge.
Explanation:
good luck
Explanation:
A whales "poop," actually helps the environment because smaller fish, microbes feed off of this. then it creates nutrients the ocean needs, it's a balance of nature. Regulating waste within the ocean...its a perfect balance of h2o quality & fish(oceanatic creature) life. like seaweed, plankton, and microbes necessary to naturally clean ocean debris...
