Why do you think chemistry will not change the decay rate of an isotope?
It depends what is meant by 'decay'. It will not alter the atomic decay rate but elements can be chemically affected by the environment which can chemically decay them.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
It stays the same. Temperature has no effect on the rate of nuclear decay.
How the radioactive decay rate be changed?
The rate cannot be changed.
What is the nuclear decay equation for T99m?
T99 is Technetion 99 has a Decay rate of 6h
What is the effect of pressure on the rate of radioactive decay?
Pressure does not affect the rate of radioactive decay. That is entirely unaffected by the environment within the nucleus of the atom.
What are the group of cells that adjusts the heart rate?
Pacemaker
Effect of calcium ions on the heart rate?
Calcium has no effect on heart rate. It does, however, have an effect on how hard the heart squeezes (inotropic effect). Heart rate is effected by the slow sodium channels in the pacemaker cells in the right atrium (and other pacemaker cells if the SA node is malfunctioning).
After how long corpse will start to decay and why corpse will decay?
Decay starts immediately upon death. Decay happens because the body's cells start to die. When the cells die, they exit the body, and dissolve into the ground. The soft tissues cells die first.
What cells set the heart rate?
answer it ya self feck head
Is a pacemaker a group of cells located in the left atrium?
A pacemaker is a device inserted into the heart to regulate the heart beats or heart rate
Why do you think chemistry will not change the decay rate of an isotope?
It depends what is meant by 'decay'. It will not alter the atomic decay rate but elements can be chemically affected by the environment which can chemically decay them.
What conducting cells set heart rate?
Sinoatrial Node (SA node)
What makes radioisotopes useful for dating objects?
They decay at a predictable rate.
What are prokaryotic cells that cause disease and decay?
Bacteria are prokaryotic cells that cause disease and decay.
Can paper decay?
Yes, but the rate of decay depends on the conditions.
How does heart rate counters work?
These work by picking up electrical signals that are released when the heart muscle cells contract.
What is the sa node?
The SA node is the "pacemaker" of the heart. Cells in the SA node are called "pacemaker" cells and they direct the contraction rate of the entire heart by generating action potentials.
