Answer: A focal spot in the x-ray setup is the area of the anode surface which receives the beam of electrons from the cathode. It is the apparent source of x-rays.
Below are some of the factors that affect its size.
Explanation:
Size of the focal spot depends on
* angle of the anode
Other prime factors that affect x-ray emission; under the control of the radiographer includes;
• Miliamperage-second (mAs)(tube current measurement)
• Kilovoltage (kVp) Controls both the quantity and quality of the x-ray beam with the speed and energy.
• Distance (d) - Related to tube design and construction.
• Tube housing
• Target material
• Filtration
• Voltage waveform
First of all we could start by verifying the clinical history. We could review past health complications, as well as present diagnosis that might be conditioning the hydration. Look for signs or symptoms such as lightheadedness, variations on the input/output of fluids, altered mental accuracy, etc. Recent gut problems and other bowels' problems should also be reviewed. Current medication should also be considered.
From a physical examination point of view, there should be a checking of vital signs, and evaluation of orthostatic blood pressure and any considerable swallowing.
Answer:
gene flow is the transfer of genetic variation from one population to another.
option D
<span>Nerve cells send electrical impulses along the axon. When these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
</span>The axon is part of the neuron (nerve cell that carries messages), as well as dendrite. Axons pass the nerve impulses on to other cells, while dendrite <span>receive nerve impulses from other cells. </span><span>The place where the axon of one neuron meets the </span>dendrite<span> of another is called a </span>synapse.
