Explanation:
Answer:
The information in the passage suggests that in mice CRY1 likely affects XPA by repressing the XPA-encoding gene transcription as shown in the graph which indicates a lowering of XPA levels when CRY1 levels is raised.

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.
Question Two: Genetic variation. As healthy as someone might be, genetic variation is required to balance the differences out. This is to prevent possible diseases that aren’t present but may be if it becomes dominant.
Question Three: Variation is a good thing for species because it allows multiple possibilities for an organism, allowing a higher chance of survival. The higher the diversity, the more likely it is for people to not die from the same genetic diseases. Similarly, in a classroom, diversity can allow people to have different ideas, opinions, and answers. This lets other learn from one another within the environment rather than just wasting time listening to something that one knows already.
