Agamogenesis is the type of reproduction which does not involve the fusion of gametes. This type of reprod uc tion is the primary form of reproduction for single-celled organisms like archarea, bacteria and protists.Plant and fungi also show asexual reproduction. Asexual reproduction involves only one parent. 2  All the off s pring are identical to the parent. 3  Asexual reproduction does not involve the process of meiosis and fertilization, hence the process does not require a mate for reproduction. 4  This type of reproduction is seen in lower forms of organisms.
Faint/Collapse. Fainting is a temporary loss of consciousness that happens when the brain does not receive enough oxygen. It comes on suddenly, only lasts for a short time and you recover fully within a short time. It is also often called a blackout. The medical term is syncope. It isn't the same thing as a seizure which usually causes jerking.
A collapse of the lung, also called pneumothorax, occurs when the air that normally circulates within your lung leaks into the space between your lung and your chest wall called the pleural space. A buildup of air increases the pressure on your lung, causing it to collapse. In most cases, only a portion of the lung collapses, leaving the rest of the lung intact. When your lung collapses, it canât expand as fully as it normally does when you try to breathe in. This can lead to shortness of breath and chest pain.
