Kirby Bauer disk technique is a method to determine sensitivity of microorganisms yo antimicrobial drugs. The greater the efficacy of the chemical the larger zone of inhibition on around the drug containing disks at lowest concentration possible or the minimum inhibitory concentration. If the chemical found on the skin of frogs produce a large zone of inhibition at a very low concentration of the drug this can be a good antibiotic.
20 teeth
By the time the embryo is eight weeks old, there are ten buds on the upper and lower arches that will eventually become the primary dentition. These teeth will continue to form until they erupt in the mouth.
Answer:
Exactly in the four elements iron, nickel, cobalt and gadolinium, there is interaction between so-called 'unpaired spins'. This interaction ensures that the magnetic moments of atoms can permanently align parallel to each other. The sum of all these small magnetizations forms the nett magnetization of the material
Explanation:
Answer: • Basic – repeated action which requires little thought or cognitive ability / perception (1)
• Closed skill – repeated running action largely unaffected by the environment / other runners (1) / Accept Open skill if linked to changing environment of runners moving positions / changing position on the road to avoid others)
• Self-paced – the speed / pace / rate of the movement is controlled by you / when running a long distance race, you decide how fast to run (1) / Accept externally-paced if linked to responding to a pace maker / other runners dictating the pace
• Gross – involves big movements of the body / involves the use of large muscle groups / movements when running do not tend not to rely on accuracy and precision (1)
