Answer:
it's false :)) i just took the test.
Explanation:
pharynx
nose
trachea
The correct answer is alveoli.
At the end of the respiratory tree, alveoli are located. These are tiny, balloon-shaped air sacs are arranged in clusters throughout the lungs. these are the site of gaseous exchange as alveoli are surrounded by thin pulmonary capillaries which allows exchange of gases. The oxygen diffuse into the blood capillaries and the carbon dioxide diffused into the alveolar space from the blood capillaries.
b. protein
c. fiber
d. cholesterol
The answer is C. In order to understand the total carbs you need fiber.
The functional unit of the kidney that filters blood and forms urine is the Nephron.
Nephron, a functional component of the kidney, is the organ responsible for producing urine as waste and extra chemicals are eliminated from the circulation.
The kidneys (pronephros) of early vertebrate embryos, amphibian larvae, and primordial fish have the most basic nephrons. Only somewhat more advanced in structure are the nephrons present in the kidneys (mesonephros) of frogs, most fish, and more advanced vertebrates during late embryonic development.
The adult kidneys, or metanephros, of land vertebrates like reptiles, birds, and mammals have the most developed nephrons.
Therefore, The functional unit of the kidney that filters blood and forms urine is the Nephron.

The nephron is the functional unit of the kidney. It filters blood and forms urine through a process involving the renal corpuscle and the renal tubule.
The functional unit of the kidney that filters blood and forms urine is the nephron. Kidneys contain millions of these tiny structures, and each nephron consists of two main parts: the renal corpuscle and the renal tubule. Blood enters the kidney through the renal artery, which splits to form a vast network of tiny capillaries. These capillaries form a tuft inside a cup-like structure known as the Bowman's capsule, which is a part of the renal corpuscle. The blood gets filtered here, and the filtrate moves into the renal tubule, where essential nutrients are reabsorbed, and wastes and excess water are concentrated into urine to be excreted.
