Answer:
Ventilation (Pulmonary) AKA Breathing
Explanation:
Pulmonary ventilation is often known as breathing. It is the means through which air moving into the lungs in the course of inspiration (inhalation) and away from the lungs at expiration (exhalation). Air flows as a result of variations in pressure between the atmosphere and the gases within the lungs.
Air, just like gases, moves from a zone of larger pressure to a zone of smaller pressure. Muscular breathing activities and recoil of elastic tissues forms the variations in pressure that causes ventilation. Pulmonary ventilation employs three seperate or distinct pressures:
-Atmospheric pressure
-Intraalveolar (intrapulmonary) pressure
-Intrapleural pressure
-Atmospheric pressure is the air pressure that is not from within but from outside of the body.
-Intraalveolar pressure is the pressure within the lungs alveoli.
-Intrapleural pressure is the pressure present in the pleural cavity.
These three pressures are important for pulmonary ventilation.
A model organism is a species that has been widely studied to understand a particular biological phenomena, normally used because they are easy to breed and maintain in a laboratory setting and has certain experimental advantage.
The criteria that Thomas hunt Morgan was looking for include; the model organism should be small in size, easy to keep in the laboratory and also able to produce large number of off springs in a short time.
Answer: Variation in a characteristic that is a result of genetic information from the parents is called inherited variation . ... This is because they get half of their DNA and inherited features from each parent. Each egg cell and each sperm cell contains half of the genetic information needed for an individual.
Explanation:
Genetic information from the parents is the result of variation.
