How do ATP and NAPH connect light dependent and light independent reactions in photosynthesis​
Finger [1]

Answer:

In plants photosynthesis occurs in two steps light-dependent stage and light-independent stage.

ATP is energy carrier and NADPH is electron carrier and both are produced during the first step from the sunlight as they carry the energy and electron to the next step which is light-independent step. In this step both ATP and NADPH are used in the formation of sugars from carbohydrates.

Therefore, these molecules connect the light-dependent and light- independent reactions of photosynthesis.

All of the following contributes to turbulent blood flow except A) when there are irregularities in the vessel wall. B) at high
GaryK [48]

All of the following contributes to turbulent blood flow except  third and fourth heart sounds.

<h3><u>Explanation:</u></h3>

The blood flow in human body is always described to be laminar. Some conditions cause the high flow when there is an ascending aorta. This causes the laminar flow of blood into turbulent. When this occurs the flow of the blood will not be smooth and linear.  

When the kinetic energy in the fluid flow increases the turbulent flow of blood occurs. Both the magnitude and the direction of the flow changes in this type of blood flow. These are caused by the irregularities in the vessel walls, flow rates to ne higher and opening of the valves of the heart.
