thirty degrees north and south of the equator‚ the warm air from the equator begins to cool and sink. Between thirty degrees latitude and the equator‚ most of the cooling sinking air moves back to the equator. The rest of the air flows toward the poles. The air movements toward the equator are called trade winds- warm‚ steady breezes that blow almost continuously. The Coriolis Effect makes the trade winds appear to be curving to the west‚ whether they are traveling to the equator from the south or

pairs exchange segments when they cross over. At metaphase l‚ the pairs line up on the metaphase plate. Microtubules from one pole attach to the kinetochore of one homologous chromosome‚ while microtubules from the other pole attach to the kinetochore of the other pair. During anaphase l the microtubules get shorter pulling the homologous pairs towards opposite poles. At telophase l two haploid cells form but the chromosomes are still double. Meiosis ll separates the sister chromatids. During

in what direction is the induced current in the part of the loop closest to the viewer? First of all‚ use the second right hand rule to find the north pole of the coil. Doing this we determine that the north pole is the left end. Since we are pulling the north pole away from the loop‚ the right side of the loop must become a south pole (in order to try and pull the coil back). This means that current must have been induced in a direction up the front of the loop. 3. The magnetic flux through

Contactors & Relays Contactors and relays are devices that open and close a set or sets of electric contacts by the action of a solenoid coil. A contactor is used to control an electric load in a control system. Contactors make or break a set of contacts that controls the voltage applied to some load in cooling systems. A contactor consists of a coil that opens and closes a set of contacts due to the magnetic attraction created by the coil when it is energized. Magnetic starters are also

A stepper Motor is basically a synchronous Motor. In stepper motor there is no brushes. This motor does not rotate continuously‚ instead it rotates in form of pluses or in discrete steps. Thats why it is called stepper motor. There are different types of motors available on the basis of steps per rotation‚ for example- 12 steps per rotation‚ 24 steps per rotation etc. We can control or operate Stepper motor with the feedback or without any feedback. A simple image of stepper motor is shown in above

Binary fission begins with DNA replication. DNA replication starts from an origin of replication‚ which opens up into a replication bubble (note: prokaryotic DNA replication usually has only 1 origin of replication‚ whereas eukaryotes have multiple origins of replication). The replication bubble separates the DNA double strand‚ each strand acts as template for synthesis of a daughter strand by semiconservative replication‚ until the entire prokaryotic DNA is duplicated. After this replicational
