Breathing is the function of our body to let air flow to the lungs. It is important because it serves the purpose of bringing the amount of oxygen the body needs to work properly, and flushing out the toxic substances our body produces.
The diaphragm also plays its important role in respiratory system because it creates more space in our chest cavity, allowing the lungs to expand when we inhale.
The larynx connects the naso- and oro- pharynx with the trachea, functioning in air conduction, vocalisation and in obstructing passage of ingesta into the trachea during deglutition. The trachea divides into left and right mainstream bronchi. Bronchi give away to smaller conducting airways, bronchioles.
The walls of the alveoli share a membrane with the capillaries, this relatively lets the oxygen and carbon dioxide diffuse between the respiratory system and bloodstream. They bring oxygen into our body through inhalation and send carbon dioxide out called exhalation and overall process is respiration
Pneumonia is a life threatening illness because if our lungs is filled with fluid then they won’t be able to function normally and won’t be able to transfer enough oxygen to your blood or get rid of the carbon dioxide in our bloodstream
B is you're answer. I did this before
Answer: don’t know really how to explain it but it’s geographic isolation
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.
Scientists and engineers actively seek evidence to test their ideas — even if the test is difficult. The reason behind is the importance of asking questions based on observations to find more information about the natural effects and proposals. From there, it is ought to determine expected results based on testing, evidence resulting from that experiment will allow testers to find out the solution they are looking for.
