Answer:
The cilia in the upper respiratory tract move mucus down toward the pharynx whereas the cilia in the lower respiratory tract move them up toward the pharynx.
Explanation:
Through the internal nares, the air enters nasopharynx from the nasal cavity. This air has dust-laden mucus. The nasopharynx is lined with ciliated pseudostratified columnar epithelium. These cilia move the mucus down toward the most inferior part of the pharynx. The lining of the larynx inferior to the vocal folds is made up of ciliated pseudostratified columnar epithelium and have ciliated columnar cells, goblet cells, and basal cells.
The goblet cells serve to produce and secrete mucus. The mucus from goblet cells helps trap dust that was not removed in the upper passages. Therefore, the cilia in the upper respiratory tract move mucus and trapped particles down toward the pharynx whereas the cilia in the lower respiratory tract move them up toward the pharynx.
It can result in decreased immunity, digestive problems, fertility problems, lower mental alertness, slowed growth. Amino acids play many different roles in the body and the symptoms vary.
Answer:
Yes.
Explanation:
Genes are passed on from generation to generation. When a male and a female produce an offspring, the offspring would get half of their genes from their mother, and the other half from their father.So your parents get half of their genes from their parents, (which in this case, are your grandparents) and they pass them on to you. Unlike your parents, you get traits from both sides of your family, some from your mother's side and some from your father's side.
This is why you share similar traits as your grandparents and at the same time,there is also a chance that you also share some (of course not all) traits with your direct cousins, because they also share some traits to your grandparents.
You can tell if asthma is related to exercise
(i) If a person has a coughing and shortness of breath. This feels a few minutes after an activity
(ii) You feel constricted. When on the exercise you feel like you can’t get enough air in your lungs.
(iii) A person feels fatigue after training instead of being energized.
(iv) If a person lives in a dry environment the breath in air that is divided and colder than the other parts of your body.
Answer:
ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
Explanation:
In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
