It is true.

The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. .

False. Oxygen is absorbed in the alveoli sacs of the lungs.

Upon inhalation Air must first pass through the larynx and down to the trachea, which then splits off into two separate bronchial tubes, the bronchial tubes divide into smaller air passages known as the bronchi and those into even smaller bronchioles. The bronchioles end in tiny sacs called the alveoli which transfer the oxygen from the inhaled air to the bloodstream.

According to the current, predominant understanding of the disorder, genetic factors alone are enough to produce schizophrenia.

Assoli18 [71]

Answer:

The answer is FALSE.

Explanation:

Schizophrenia is a personality disorder that affects a person's ability to think, feel and behave clearly.

Although there is a very strong genetic component to schizophrenia, genes alone do not completely explain the illness. Rather it is believed that genes do not directly cause schizophrenia, but do make a person vulnerable to developing the disease alongside other factors such as the environment and altered brain chemistry and structure.

What is the difference between a bony fish and a cartilaginous fish?

blondinia [14]

Bony fish belong to Class Osteichthyes, while cartilaginous fish belong to Class Chondrichthyes. Bony fish have a bony skeleton, while cartilaginous fish have one composed mostly of cartilage. Bony fish have body coverings of scales, while cartilaginous fish are covered with dendritical projections (think shark skin).
Bony fish are found in fresh and salt water; cartilaginous fish are found only in salt water. Bony fish have gills covered by an operculum; cartilaginous fish have gill slits. Bony have no eyelids; the cartilaginous fish do. Bony fish have an air-filled swim bladder; cartilaginous fish have an oil-filled liver to keep them bouyant. Hope this helps! Whew!
