Answer:
Systosolic blood pressure
Explanation:
The systosolic blood pressure occurs when the heart is contracting and pushing the blood round the body. It is more important than diastolic blood pressure.
When the heart beats, it contracts and pushes blood through the arteries to the rest of your body.
This force creates pressure on those blood vessels which are the arteries, producing the systolic blood pressure as compared to diastolic blood pressure that measures the lowest block pressure between heartbeats.

Answer:
d) 625 grey wolves
Explanation:
Number of grey wolves in yellowstone;
1997 = 100 wolves
2002 = 275 wolves
Between 1997 and 2002 (a five year period), number of wolves increased by; 275 - 100 = 175 wolves
Population growth rate between 1997 and 2002 = 175 wolves per 5 years
Note that the population growth continued at the same rate from 2002 to 2012 (a ten year period).
Therefore;
if; 5 years = 175 wolves
10 years = (175 × 10) / 5 =350 wolves.
therefore, number of wolves between 2002 and 2012 = 350 wolves.
Number of wolves as at 2002 = 275 wolves
total number of wolves at 2012 = 350 + 275 = 625 wolves
