The diagram of water cycle includes the evaporation of water from water bodies. This is often expressed by an arrow or a bunch of arrows that arise from the water body and point towards the sky.
Some diagrams also symbolically show the evaporation process as water vapor that is symbolised with wavy curved arrows
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

<span>The muscle is a soft tissue found in most animals. The cells in the
muscle contain protein that produces a contraction that changes both the length
and shape of the cell. They are responsible for the movement it produces in the
human body. There are three types of muscle cell: skeletal, cardiac and smooth
muscle. Cardiac muscle contains excess amounts of mitochondria and myoglobin. The
myoglobin is responsible for the red color of the muscle. The answer is letter
B.</span>
