31 pairs<span>In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body. Near the spinal cord each spinal nerve branches into two roots.
Hope this helps!!!</span>
An autotroph is an organism that can produce its own food using light, water carbon dioxide, and other chemicals.
Answer:
RNA - single stranded, contains uracil, and protein synthesis.
DNA - Double stranded, contains thymine, and stored genetic material.
Hope that helps! :)
while standing on the diving board you'd have potential energy. after jumping you'd have kinetic energy.
Systolic pressure is the maximum pressure produced in the arms and legs when the left ventricle contracts.
Systolic pressure is the peak blood pressure experienced during ventricular contraction, and diastolic pressure is the lowest pressure felt right before the subsequent contraction. As in 120/80 mm Hg, the blood pressure is typically expressed as the sum of the systolic and diastolic pressures.
<h3>What time does the blood volume in the ventricle reach its peak?</h3>
End-diastolic pressure is at its resting level (end-diastolic pressure) and ventricular volumes are at their maximum value when the heart muscle is relaxed (end-diastolic volume).
<h3>How does the left ventricle generate the highest blood pressure?</h3>
Systolic blood pressure is generated when the left ventricle (LV) contracts, and it ranges from 100 to 140 millimeters of Hg (mm Hg). Aortic diastolic pressure typically ranges from 60 to 90 mm Hg. Blood flows through the aortic valve due to the gradient in pressure between the LV and aorta.
<h3>What is the ventricles' maximum pressure?</h3>
peak pressure of approximately 120 mmHg (systemic) or 25 mmHg (pulmonary circulation)
