Dragonflies are most closely related to damselflies. Damselflies are smaller, slimmer, and most of them fold their wings along their body when they are resting.
Regurgitation influences the flow of blood by mixing the oxygen-poor blood with the oxygen-rich blood. Due to this, the heart has to pump more to oxygenate the entire body, leading to the rapid, and fluttering heartbeat. The tissues get oxygenated but regurgitation could be fatal, as the heart cannot function overtime forever.
Valve prolapse influences the flow of blood when the flow of blood backs up. This leads to an irregular or racing heartbeat. Even at certain occasions, the blood can flow back to the lungs. However, there is not a huge influence in the oxygenation of the body tissues.
Stenosis makes the ventricles to pump overtime to get enough blood through, and in the process, the ventricles thicken. This functions for a while, however, it will result in heart failure as the heart cannot do it for entire life. The tissues are oxygenated, but it will be an issue due to overtime.
<span>The correct answer is multinucleate tissues, occurring naturally during the physical body work in conjugation with the plasma of the membranes of the cells. In summary, the skeletal cells are multinucleate because they are the result of the union between the muscular cells and the soft cells of the muscle. The reason they are multinucleate is because they facilitate the circulation of stem cells during the most demanding muscular movements. Stem cells help multinucleate tissue communicate faster.</span>

External fertilization is the kind of fertilization that happens outside the female body. The female will put the unfertilized egg outside and the male will eject the sperm later.
This will cause the sperm have to mobilize further to the egg than internal fertilization. That makes this method only viable in water or highly moist area.
