Nuclear power plants use the nuclear fission reaction to release energy and generate electricity through energy conversion. Take the pressurized water reactor nuclear power plant as an example to illustrate its working principle.
In the pressurized water reactor, a large amount of heat is generated by the self-sustaining chain fission reaction of the nuclear fuel nucleus. The coolant (also called the heat carrier) brings the heat in the reactor to the steam generator and transfers the heat to the working medium, water. The main circulation pump then delivers the coolant back to the reactor for recycling, thereby forming a circuit called the first circuit. This process is also the energy conversion process of nuclear fission energy converted into thermal energy.
The working medium on the secondary side of the U-tube outside the steam generator is vaporized by heat to form steam. The steam enters the steam turbine to expand work, and converts the heat energy released by the steam enthalpy into the mechanical energy of the rotor of the steam turbine. This process is called thermal energy conversion to mechanical energy. The energy conversion process. The steam that has done work is condensed into condensed water in the condenser and returned to the steam generator to form another circulation loop called the second loop. This process is called the energy conversion process of converting thermal energy into mechanical energy. The rotating rotor of the steam turbine directly drives the rotor of the generator to rotate, so that the generator emits electric energy, which is an energy conversion process that converts mechanical energy into electrical energy.
Answer:
Mountains are cooler than plains because with increase in height the temperature decreases. EXPLANATION: Mountains are located in high elevations and plains are located in low elevations. Their respective heights are measured by term called as their height above sea level.
<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
Answer:
(1) In order to move your muscles need to ligaments.
(2) Joint holds bones together.
(3) Tendon connects bones to muscles.
Explanation:
Ligaments are strong bands of tissue which are responsible for the movement of bones in the body. Joints are the place or point where two bones are attached. Tendons are responsible for connecting muscles of the body to the bones.
If a cytosine base is substituted for by a thymine base in a DNA segment during DNA replication, the sequence could code for the wrong amino acid during translation.
The change in the sequence of DNA is known as mutation.
When a base substitution occurs in the sequence of a DNA during replication, the genetic information in the region where the substitution occurred becomes compromised.
During transcription, the process of encoding genetic information on DNA into RNA, the base substituted is also transcribed along. If cytosine is substituted by thymine, adenine is transcribed instead of guanine.
During the translation of the genetic codes, the wrong amino acids might end up being translated due to the substituted base, leading to a faulty protein.
