He discovered a new type of medicine that could treat infections.
He discovered the 1st antibiotic (penicillin).
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.
Speciation is the
process by which new and distinct species are formed. One of the most important
factors necessary for speciation to occur is the genetic isolation of two
populations. This genetic isolation can, over long periods of time, cause these
two groups to become genetically incompatible. Factors that can lead to this
genetic isolation include geographic separation and hostility among population
groups.
Answer:
three
Explanation:
Each codon consists of <em>three nucleotides</em>, usually corresponding to a single amino acid. The nucleotides are abbreviated with the letters A, U, G and C.
Assuming that you followed the parentage of people and primates, you would sooner or later show up at a common precursor that was neither a cutting edge ape nor a human.
<h3>What makes humans different from other Apes?</h3>
- People have an "S" shapes spine with a more limited straight firm more extensive more bowl-like pelvis.
- While Apes have a "C" formed spine and an introvert restricted pelvis.
- People knees are calculated inwards (valgus point - the point the femur makes at the knee) so the knee sits closer the focal point of gravity.
- The knee joints are bigger.
- Individuals have considerably more mind boggling types of verbal correspondence than some other primate species.
- We are the main creature to make and involve images for the purpose of correspondence.
- We additionally have more changed and complex social associations.
