Answer:
Wolves and coyotes will compete for resources and the coyote population will decrease and wolves might decrease from competition as well. The increase of predators (wolves and coyotes) will cause the raven population to go down. If the raven eat grass then the grass population will go up becuase more ravens are getting eaten= no one eating grass.

Question: The stethoscope is a device commonly used by doctors to monitor heart function. When listening to a heart beating using a stethoscope, the doctor hears the characteristic "lub-dub" sounds. The lub sound represents the (1)____ of the atrioventricular valves and the dub sound represents the closure of the valves between (2)____.
1. closing or opening
2. the arteries and atria, the ventricles and arteries, or the atria and ventricles
Doctors can also use stethoscopes to monitor respiratory function. A wheezing or whistling sound most likely indicates (3)____
Answer:
The correct answers are:
1. closing
2. the ventricles and arteries,
3. a constricted trachea
Explanation:
Lub being the first sound can be heard during the closing of the tricuspid and mitral or the bicuspid valves present in between the atria and the ventricles.
The tricupsid is present between the atrium and ventricle of the right hand side and mitral at the middle of the atrium and ventricle of left side. They helps in prevention of the reverse flow of the blood from the ventricles to their respective atria.
Dub is the second sound produced during the closing of the pulmonary and aortic valves that are present in middle of the left artery and aorta.
They prevent reverse blood flow from arteries into the ventricle. Diastole is the time gap of two sounds which is known as ventricular filling
Wheezing is the high pitched sound that is being produces when a person starts breathing, especially during exhale. It happens during constriction of the airways or the inflammation. This is also taken as a symptoms of diseases like asthma, COPD, allergies, bronchitis etc.
I believe the technique is Systematically focus on different segments of the sky for short intervals. Pilots must always be watchful for other aircraft. An effective scan is performed by systematically focusing on different segments of the sky for short intervals normally 1 or 2 seconds per segment. First look in the direction of the turn, raising or lowering the glider's wing to view above and below.
