Explanation:
1) As human age, their respiratory system also ages making gaseous exchange less and less effective. With age the bone and muscular strength of tissues that keep the respiratory tract open lessen and it becomes the tract slowly collapses. The alveoli also age and become baggy losing their shape. The dead space between alveoli also increases.
This is accelerated by some environmental conditions such as air pollution and smoking. When particulate matter settles in the lungs and alveoli, it causes accelerate damage to the lung tissues and scarring. This is why people in chronically polluted areas, generally speaking, live less longer than people in cleaner environments especially due to respiratory problems they develop.
2) The oral cavity- Includes the lips, teeth, and tongue. The structures serve as articulators. The pharynx and the oral cavity- Both act as resonators that selectively amplify to varying degrees of intensity, fundamental tones and overtones. The larynx- An organ consisting of a cartilaginous framework containing muscles and joints. The vibratile part of the larynx are the vocal folds which are the producers of sound. The Lungs- They supply a stream of air which passes through the trachea.
3) Gas exchange occurs between the alveoli sacs and small capillaries of the circulatory system. Via this exchange, oxygen is delivered from the lungs to the bloodstream. The oxygen attaches to the hemoglobin of red blood cells. The red blood cells then transport the oxygen to cells, such as those located in your muscles.
Answer: <em><u>The mice are eating all the vegetation?</u></em>
Explanation:
The only thing i could think of is the mice taking over because there's a larger amount which would cause a small population of the salamanders.

The statement that correctly defines coevolution is:
D: Two entirely different species affecting each other's evolution, as in predator-prey relationships.
Another example of coevolution is host-parasite relationship, which happens between totally separated species, but affects the way both of them will evolve.
Answer:
Domain: eukaryotic
Kingdom: Animal
Explanation:
The Animalia kingdom constitutes the group of eukaryotic, heterotrophic, multicellular and tissue organisms, characterized by their capacity for locomotion, their embryonic development and the absence of chlorophyll. Animalia is a kingdom comprised in the Eukaryota domain.
Taxonomically, eukaryotic, is the domain (or empire) to which the organisms formed by cells with a true nucleus belong.
