b. The nose
c. The pharynx
Answer:
c. The pharynx
Explanation:
The pharynx is a tubular organ that begins in the funnel-shaped neck down the neck, extending from 12 to 15 cm in length and about 35 mm at its onset and about 15 mm at the end. its ending. It has communication with the esophagus, nasal passages and the ears. The pharynx is located behind the nasal passages and in front of the cervical vertebrae, remains attached to the larynx and esophagus.
Simply put, we can say that the pharynx is a funnel-shaped passageway that connects the nasal and oral cavities to the "voice box," also known as the larynx.
Answer: I do think its a good idea cause it lessens pollution in the air we breathe in and stops us from burning fossil fuels
Explanation:
Banning passenger cars and promoting public transportation in cities is a good idea for reducing pollution and traffic congestion.
I believe that banning passenger cars and promoting the use of public transportation in cities is a good idea. This approach can help reduce air and noise pollution, alleviate traffic congestion, and improve overall quality of life. By encouraging people to walk, bike, or use public transportation, cities can create a more sustainable and livable environment for their residents.
One example of a city that has successfully implemented this approach is Copenhagen, Denmark. The city has an extensive public transportation system, including a well-connected network of bike lanes. As a result, more than 60% of residents commute by bike or public transportation. This has significantly reduced air pollution and traffic congestion in the city.
Additionally, adopting this approach can have numerous benefits, such as promoting physical activity, reducing carbon emissions, and improving public health. Overall, I believe that cities with comprehensive public transportation systems should consider implementing policies that restrict the use of passenger cars in order to create a cleaner, more sustainable urban environment.
The correct answer is - B) more; in total.
The urban areas use much more energy than the rural areas, by far. The reasons for that are numerous, with the two biggest being the number of people and the industry.
The number of people living in urban areas is higher than the number of people living in rural areas. Also, the people in the urban areas use much more energy because they rely on much more technology, technology that uses energy in order to work.
Most of the industry is also located in and around the urban places. The industry is a huge consumer of energy, thus increasing the usage of energy further more.
Answer:
Explanation:
Synthetic is something that is not made from natural materials but rather made from the synthesis of other materials in a lab. This is mostly done in clothing where you have some natural materials like cotton and other materials that are synthetic. This doesn't mean it is not high quality. It is actually preferable for some sports for example to wear synthetic clothing instead of cotton.
Answer:
Cilia are motile in the lungs responsible for keeping the airways clear of dirt and mucus by their characteristic beating motion and rhythmic waving allowing a person to breathe easily and without irritation. These are present in both the lungs as well as middle ear.
As in Primary ciliary dyskinesia , there are defects in the action of cilia in the lining of the respiratory tract , middle ear , sinuses , eustachian tube etc the cilia cannot peforms its regular role .Infections can lead to an irreversible scarring and obstruction in the bronchi resulting in :
1) Shortness of breath.
2) Recurring chest colds.
3) Sinusitis.
4) Coughing , gagging , choking,
5)Middle ear infections
Answer: The respiratory wall or mucosa is made up of the epithelium and supporting lamina propria. The epithelium of respiratory tract is tall columnar pseudostratified with CILIA and goblet cells The cilia aids in sweeping away dusts and bacteria that adheres to the mucous on the epithelium. Therefore people with Primary ciliary dyskinesia are prone to Respiratory infections.
Explanation: Primary ciliary dyskinesia also called immotile ciliary syndrome is a rare genetic disease that affects the movement of cilia lining the respiratory tract. The major consequences of this dysfunction is reduced or absent mucus clearance from the lungs which subsequently leads to chronic recurrent respiratory infections
I hope this helps. Thanks!
Schleiden and Schwann suggested the cell theory. It is stated that a single cell makes up every living thing. It implies that the structural and basic unit of life is the cell.
Understanding how cells form, grow, and die enables us to comprehend how all living things function.
Our comprehension of a variety of subjects, including as how new life is created, why organisms take on particular forms, how cancer spreads, how diseases can be treated, and more, is assisted by this collection.
Cells make up all known living things. The structural and operational unit of all living things is the cell. The chemical makeup of each cell is same. Cells are where all of life's energy flow (metabolism, biochemistry) takes place.
Therefore, adult human form singled cell zygotes.

Answer:
The adult human forms from the single-celled zygote.
Explanation:
The cell theory was put by Schleiden and Schwann. It is said that all the living organisms made up of from a single cell. It means the cell is the structural and fundamental unit of life. In human beings, it is also seen. The human comes from the fertilization of haploid sperm and ovum. The zygote is the single fertilized cell that undergoes cell division to form multicellular organisms. The single-cell zygote becomes a multicellular gastrula and forms the 3 germ layers. These three germ layers later form different tissues and organs by organogenesis. This happens due to the mitotic cell division. Thus an adult human will form and the cell division continues till the death of the individual. This process indicates how a single-celled zygote forms the multicellular human.
