The atmosphere is a difficult place for a microbe to survive. Biology prefixes and suffixes help us to understand biology terms. Aerospace is a term used to collectively refer to the atmosphere and outer space.Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. In science, dactyl is used to refer to a digit such as a finger or toe. Aerospace engineering consists of aeronautics and astronautics.Aerospace organizations research, design, manufacture, operate, or maintain aircraft and spacecraft.. Physical Environment Stresses. [aero- + G. -osis, condition] Medical Definition of Aer-, aero- Medical Author: William C. Shiel Jr., MD, FACP, FACR Aer-, aero-: Prefix indicating air or gas , such as aerogastria (excess stomach gas). This essential process is a way for a cell to break the bonds of molecules in order to provide life-sustaining energy in the form of adenosine triphosphate. All living cells must undergo a process referred to as cellular respiration. Dessication is the primary stress that aeromicrobes face, and it limits the amount of time that they can survive while suspended in the air (Pepper 2011). aerobic adj. Aerobic exercise is any type of cardiovascular conditioning or “cardio.” During cardiovascular conditioning, your breathing and heart rate increase for a sustained period of time. aerosis: ( ār-ō'sis ), Generation of gas in the tissues. Definition. Aeronautics is the study of the science of flight.Aeronautics is the method of designing an airplane or other flying machine. Definition: The word dactyl comes from the Greek word daktylos which means finger. There are four basic areas that aeronautical engineers must understand in order to be able to design planes. The definition of aerobic is needing oxygen for life or activity. The affix dactyl denotes a digit such as a finger or toe. 'Aero' refers to oxygen, so aerotolerant means the cells can tolerate the oxygen. Biology.Living or occurring only in the presence of oxygen: aerobic bacteria. What does aerobic mean?
