To get an average, you must add all of the numbers together, and divide that sum by the amount of numbers there are. There are 6 number, which is what we must divide by.
6.8g is the average for the set of measurements.
Answer:
The cells on the cornea are maintained by pheripheral vessels and surrounding fluids.
Explanation:
*- The capillaries of the limbus nourish the peripheral part of the cornea.
*- Tears supply of glucose in the tear film

Answer:
The correct answer will be- nasal septum
Explanation:
The nasal cavity is the hollow space or cavity connected to the two nostrils which allow the inhalation and exhalation of the air into the nose.
The nasal cavity is divided into left and right portion by a cartilaginous bony structure called nasal septum. The nasal septum lies in the central position and divides the nasal cavity into symmetrical portions.
Thus, the nasal septum is the correct answer.
<span>The correct option is A. Founder's effect is the reduced genetic variability that occur as a result of population production from a small number of colonizing parents. The founder's effects is one of the ways by which nature can randomly produce new species from existing population.</span>
These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.
In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.
SHORT ANSWER:
Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
