4 The graph below shows how the activity of an enzyme changes
choli [55]

Answer:

A

Explanation:

A. The optimum pH of the enzyme is 6.6.  - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)

B. The optimum pH of the enzyme is 5.8.  - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80

C. The enzyme's activity is greater around pH 8.0 than around  pH 5.0  - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.

D . The enzyme's activity continually increases as pH increases  from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

when measuring the blood pressure, the cuff is deflated until two consecutive beats are heard through the stethoscope. This meas
dem82 [27]

Answer: Systolic pressure.

Explanation:

Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.  

For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.  

So, <u>the systolic blood pressure is registered with the stethoscope when the cuff is deflated.</u> When two heartbeats are heard, the pressure gauge reading is recorded. <u>When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.</u>
