Answer:
10 meters/second.
Explanation:
Unladen swallow consists of two species are <em>Hirundo domicella </em>and the <em>Hirundo spilodera</em>.
The average speed of unladen swallow comes out to be 10 meters/second. The maximum speed can go upto 13-14 meters/second. The speed of unladen swallow can be calculated by the formula given by Graham K. Taylor. According to graham the speed of unladen swallow is 3 times of the product of frequency and amplitude. ( v= 3fA, v is velocity, f is frequency and A is amplitude).
The last option is the most accurate
Hope this helps!
Based on the scientific method, for the scientist using radioactive dating to determine the age of a fossil, the best way to increase reliability is by doing repeated analyses of the fossil finding it to be the same age each time.

Answer: The bacteria uses the oxygen present in the mouth.
Explanation:
The plaque that is formed in the teeth is a highly anaerobic bacteria but it can sustain in the environment rich in oxygen. The oxygen is used by the bacteria and there is a absence of oxygen in the teeth.
It is formed in between the teeth which needs oxygen to survive and if remains for tooth for a longer period of time then it began to grow without oxygen.
It basically uses the oxygen available in the mouth and makes the condition anaerobic.
Emir is most probably taking a class on human anatomy. Human anatomy involves all the structures in the composition of the human body. Human anatomy can be studied either by systems (i.e. cardiovascular system, respiratory system, etc.) or by regions (i.e. thoracic anatomy, abdominal anatomy, pelvic anatomy, head and neck anatomy, etc.) depending on the course.
