Which procedure should Juan use to test his hypothesis?
A. Survey northern and southern residents about the birds in their areas.
B. Observe the direction the birds fly when they depart in the winter.
C. Tag the hummingbirds with transmitters and track their movement.
D. Set up observation posts in the south to verify the time of year that birds arrive.
The answer to this question is C. Tag the hummingbirds with transmitters and track their movement.
Explanation:
To prove or disprove his hypothesis about birds Juan needs to test the direction hummingbirds fly to during the winter because only in this way he can know if the birds fly to the South as he thinks or they go to a different place. Moreover, this can better be tested through precise instruments such as trackers because these will register the movement of birds and clearly show if they are going to the South. Moreover, others such as the opinions of residents or the initial direction when birds migrate might be inaccurate.
The urinary bladder is typically is not affected by pelvic inflammatory disease. This disease is more commonly known as PID. People can get PID by having an untreated STD, have more than one partner, or use an IUD to prevent pregnancies, among others. At this time, there is no test that can be given to diagnose PID. A doctor can diagnosis this by using a persons medical history, other tests results, and a physical examination. Some, but not all, of the symptoms for PID are; fever, pain in the lower abdomen, bleeding between periods, and a burning sensation when you urinate. PID can be cured if found in the early stages.
