The pressures in the atria and ventricles that would cause the AV valves to open. This is when the pressure in the atria would be greater than the pressure in the ventricles.
<h3>What does pressure in the atria cause?</h3>
The pressure drops below 120 mmHg as the ventricles relax, causing the semilunar valves to close. As the pressure continues to fall, the atrial pressure exceeds that of the ventricles, and the atrioventricular valves open. Meanwhile the blood is being pumped around the body.
With this information, we can conclude that the pressure in the atria would be greater than the pressure in the ventricles.

The term fastidiousness refers to the complexity of an organism's nutritional requirements. A fastidious microorganism will only grow if the culture medium provides the necessary nutrients. This table provides the readings on the optical density from bacterial cultures. This reading gives an indication of the concentration of the bacteria in the culture; the higher the concentration of bacteria, the greater scatter of light and the higher value of optical density. Yeast extract broth, nutrient broth and glucose broth are culture media which are enriched with more nutrients. In all these three media, <em>S.mitis</em> had the lowest optical density, meaning the lowest concentration. We can conclude that <em>S.mitis</em> is the most fastidious microorganism of the three. Then comes <em>A.faecalis</em> and the least fastidious of the three is <em>E.coli.</em>

Leaves are colored by molecules called pigments. The pigment that causes leaves to be green is chlorophyll. Chlorophyll is important for plants to make food using sunlight. During spring and summer when there is plenty of sunlight, plants make a lot of chlorophyll.
In autumn when it starts to get cold, some plants stop making chlorophyll. Instead, those plants break down chlorophyll into smaller molecules. As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall.
