Normal blood pressure is 120/80. Which best describes the blood pressure reading? The systolic pressure is 120, and the diastolic pressure is 80.
The diastolic pressure is 120, and the systolic pressure is 80.
Systolic pressure is measured when the blood flow resumes as the cuff deflates, so systolic pressure is always the lower number.
Diastolic pressure is measured when the blood flow resumes as the cuff deflates, so diastolic pressure is always the lower number.

The systolic pressure is 120, and the diastolic p

ressure is 80.

Explanation:I did the Test review

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
