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 air that normally circulates within the lung leaks into the space between the lung and the chest wall, pushing the lung down or causing it to collapse. This causes the affected section of the lung to shut down.In most cases, only a portion of the lung collapses, leaving the rest of the lung intact. A severe lung collapse can cause low blood oxygen levels, respiratory failure, cardiac arrest, and shock.urgery. If an air leak from the lung is the underlying cause of the collapse, surgery may be necessary to repair the leak. Your doctors will make two small incisions in your chest and insert a fiber optic camera into one of them to view the lung.
