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:
Can i see the options choices
you question is incomplete??!!!
Explanation:
There are choices for this question namely:
1. Sterile
2. Reproductive
3. Both
4. Neither
The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.
Answer: C) Increase the yield of electricity
This is because the whole purpose of photovoltaics is to 'capture' electrons to generate a flow of electricity.
