Answer:
Brain cells are very sensitive and when they do not have oxygen they slowly start dying off which leads to brain damage.
Explanation:
Glycolysis produces important electrons and ATP which allow cellular respiration and fermentation to occur.
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
The correct answer is the interphase.
The cell cycle consists of three phases: the interphase (G1, S, G2) the mitotic (M) phase, and cytokinesis. <span>The first checkpoint of the cell cycle is G1 checkpoint which is between G1 and S phase when cell checks its size, nutrients, molecular signals, DNA integrity. The second checkpoint is G2, just before the mitotic phase, when cell checks DNA integrity and DNA replication. Those two checkpoints are the ones before division, other like M checkpoint is during the mitosis.</span>
A major study has shed new light on the dim layer of the ocean called the "twilight zone" -- where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere.
