There are no probably-true statements on the list of choices that you provided.
NoseIt - is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration. It also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose there is the olfactory mucosa and the sinuses.
turbinate(or nasal concha)- is a long, narrow and curled bone shelf (shaped like an elongated sea-shell) which protrudes into the breathing passage of the nose. The turbinates divide the nasal airway into three groove-like air passages -and are responsible for forcing inhaled air to flow in a steady, regular pattern around the largest possible surface of cilia and climate controlling tissue.
Sinus- A sinus is a sack or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue.
Paranasal- Paranasal sinuses are air-filled spaces, communicating with the nasal cavity, within the bones of the skull and face The paranasal sinuses are joined to the nasal cavity via small orifices called ostia.
Pharynx-The section of the alimentary canal that extends from the mouth and nasal cavities to the larynx, where it becomes continuous with the esophagus.
Larynx- Voice box
Epiglottis- The thin elastic cartilaginous structure located at the root of the tongue
Trachea-A thin-walled, cartilaginous tube descending from the larynx to the bronchi and carrying air to the lungs. Also called windpipe.
Bronchi-The two main brances of the trachea, leading directly to the lugns.
Bronchiole-The fine, thing-walled, tubular extensions of a bronchus.
<u>Answer</u>:
(B) A pot being heated by an electric burner
(D) A radiator that emits warm air and draws in cool air
(E) A hot air balloon rising and falling in the atmosphere
These are some of the examples of the convection currents.
<u>Explanation</u>:
Earlier, electrons were believed to have positive charges and then electric current were discovered. But later after the invention of electric current and current which is termed to be the flow of electrons and is usually flows from negative to positive terminal. But its convention is not discarded in which current moves from positive terminal to negative and it is called convention current. The direction of current shown in the circuit is said to be the convention current.
Hence, the following are the examples of convention current.
1. Boiling water - The energy travels into the pot from the burner, boiling down the water. Then this warm water is accumulating on the top and colder one is heading down to absorb it, triggering a circular motion.
2. Radiator - Place hot air at the peak and pull cool air at the bottom.
3. Hot air balloon - The air is warmed up by a heating element within the balloon, so the air jumps upwards. This induces the balloon to increase in size due to the inside trapping of the warm air. He removes a few of the warm air when the pilot commences to dive, and cold air takes place, enabling the parachute to drop.
