Answer: A
Baroreceptors and chemoreceptors both work within the walls of the arteries, sending out impulses to raise or lower blood pressure, whereas the kidneys help control blood volume.
Baroreceptors and chemoreceptors function primarily within the arterial walls to detect changes in blood pressure and chemical composition, respectively, while the kidneys are responsible for regulating blood volume by managing salt and water balance.
A) Baroreceptors and chemoreceptors both work within the walls of the arteries, sending out impulses to raise or lower blood pressure, whereas the kidneys help control blood volume.
This option accurately describes the distinct roles of baroreceptors and chemoreceptors in the cardiovascular system, emphasizing their location and function in regulating blood pressure. It contrasts this with the kidneys' role in managing blood volume, making it the correct choice.
B) Baroreceptors and chemoreceptors both work to help maintain blood volume, whereas the kidneys take care of salts, water, and waste removal.
This statement is incorrect as it misrepresents the primary function of baroreceptors and chemoreceptors. They do not directly maintain blood volume; rather, they detect changes in blood pressure and chemical levels, while the kidneys are the ones that regulate blood volume through salt and water management.
C) Baroreceptors and chemoreceptors must work together to control blood pressure, whereas the kidneys work with the adrenal cortex.
This choice inaccurately suggests that baroreceptors and chemoreceptors must work in unison to control blood pressure. While they both play a role in blood pressure regulation, they operate independently. Additionally, while the kidneys do interact with the adrenal cortex, this does not highlight the major difference between the renal function and that of the receptors.
D) Baroreceptors and chemoreceptors are both located near the adrenal cortex, whereas the kidneys are located near the heart.
This option is incorrect as it inaccurately states the locations of baroreceptors and chemoreceptors. These receptors are primarily found in the arterial walls, not near the adrenal cortex, which makes this option factually wrong in the context of their anatomical locations.
Conclusion
Option A is definitively correct as it clearly delineates the functional roles of baroreceptors and chemoreceptors in regulating blood pressure through impulses from within the arteries, contrasting this with the kidneys' function in controlling blood volume. The other options fail to accurately represent the mechanisms or locations of the components involved, thus reinforcing the validity of the correct answer.
9. Which sound waves have a lower pitch?
Answer: B
Sound waves that are farther apart have a lower pitch.
When sound waves are farther apart, they have a lower frequency, which results in a lower pitch. This phenomenon is a key component of the Doppler Effect as described in the provided extract.
A) Sound waves that are closer together
Sound waves that are closer together have a higher frequency, which means they produce a higher pitch. This is the opposite of what the question is asking, as the closer proximity of sound waves leads to increased frequency rather than decreased.
B) Sound waves that are farther apart
Sound waves that are farther apart have a lower frequency, resulting in a lower pitch. This aligns perfectly with the explanation in the extract regarding how wave spacing affects the sound heard by the listener, making this the correct answer.
C) Sound waves that travel a long distance
The distance that sound waves travel does not directly determine their pitch. While sound can lose intensity over long distances, the pitch is more closely related to the frequency of the waves, which is not inherently affected by distance alone.
D) Sound waves that travel a short distance
Similar to option C, the distance traveled by sound waves does not dictate their pitch. Sound waves can be of any frequency regardless of the distance they travel, thus this option does not accurately answer the question.
Conclusion
The correct answer is definitively B, as it directly correlates with the established relationship between wave frequency and pitch. Other options either misinterpret the relationship or are irrelevant to the concept being tested regarding the Doppler Effect. Understanding that farther apart sound waves indicate a lower frequency is crucial for grasping this scientific phenomenon.
