How is PVR (pulmonary vascular resistance) determined?
Alla [95]

Answer:

PVR is calculated by the formulae:  \text{Mean PVR}=\frac{\text{mean PAP-PAOP}}{\text{CO}} \times80

Explanation:

Pulmonary vascular resistance may be defined as the resistance to blood through the pulmonary circulation.  

PVR can be determined by the following formula:

\text{Mean PVR}=\frac{\text{mean PAP-PAOP}}{\text{CO}} \times80

Here, PAP is the pulmonary artery pressure, PAOP is pulmonary artery occlusion pressure and CO is cardiac output.

in the process of photosynthesis and aerobic respiration why the amount of oxygen and carbon dioxide remains the same?
fiasKO [112]

Plants capture sunlight to acquire energy needed to produce their own food. Photosynthesis uses light energy to convert water and carbon dioxide into glucose and oxygen. Cellular respiration provides usable energy for the cell in the form of ATP. Water and carbon dioxide are products of cellular respiration.

Understanding what you do about the structure of DNA so far, do you think that every organism's DNA will look and act the same?
Over [174]
Every organism’s DNA will not look and act the exact same way. If the parent reproduces asexually is the only exception to that rule. However, if all organism’s DNA resembled and acted as a deer’s DNA, then all organisms would be deer. Therefore, there are genetic differences that separate species and ensure different behaviors from organism to organism. While the DNA will be similar by using the same four nucleic bases, there is an entirely different combination of those bases from organism to organism.
