Answer:
P wave and R wave
Atrial contraction = P wave
Ventricular contraction = R wave
Explanation:
The behavior of the frog heart from force recording can be classified into ; P wave and R wave.
utilizing the ECG ( Electrocardiogram) data the aspect of the force recording that is due to atrial contractions is the ; P wave while the force recording that is due to ventricular contractions is the ; R wave the ventricular contractions is also known as QRS
ECG is used to record the electrical activities of a heart at rest
Hallo~~~
When comparing optical and radio telescopes, we know that both of these telescopes detect a certain band of the electromagnetic spectrum.
When contrasting optical and radio telescopes, we know that optical telescopes have higher equipment (polished mirrors, accuracy), and that they depend on weather. Radio telescopes have lower equipment (less precise reflectors), and depend on diff. things such as thermal radiation and man-made emissions.
Answer:
The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.
Explanation:
Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria
If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.
When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.
The answer is 1.2 m³
1 L = 1 dm³
1,200 L = 1,200 dm³
1 dm³ = 0.001 m³
1,200 dm³ = 1,200 * 0.001 m³ = 1.2 m³
Answer:
Neurotransmitters
Explanation:
Neurotransmitters are the chemicals that are released from the axon terminals of the pre-synaptic neurons of the synapse. These chemicals have receptors at the surface of the dendrites of postsynaptic neurons of the synapse. Binding of neurotransmitters to their receptors brings about the excitatory or inhibitory effect on the postsynaptic neuron. Accordingly, the action potential is fired. In this way, electrical signals are passed from one neuron to the next at the synapse. Acetylcholine is an example of neurotransmitters.
