Answer:
The procedure is called Respiratory endoscopy or bronchoscopy.
Explanation:
This kind of procedure is able to take a look down into the respiratory tract in order to observe possible symptoms of some diseases. As the endoscope can reach the bronchi, it's possible to extract a piece of tissue in order to analyze it and understand better the patient's diagnosis.
Answer:
1) Movement to area of lower concentration: facilitated diffusion . It consists in the diffusion of a substance through a membrane in favor of its concentration gradient, that is to say that there is movement from an area of greater concentration to another of less concentration.
2) Movement assisted by proteins: both. In the facilitated diffusion the molecules must pass through membrane proteins. In active transport, the proteins involved are called pumps that normally use chemical energy.
3) Requires energy active transport: active transport makes use of energy for the movement of molecules because the movement is against a concentration gradient.
4) Sodium ion transport out of the cell: It is a type of active transport because it requires energy to allow movement against its concentration gradient, the ATP supplies the energy.
5) Glucose transport into cell: It is a type of diffusion facilitated through membrane proteins.
6) Movement across a membrane: both
Answer:
D. her skeleton was 40% intact and undisturbed
Explanation:
Lucy was one of the most important discoveries in human evolution. Before the finding of Lucy majorities of the human ancestor bones were not much more than only some bone fragments.
Lucy was the first most complete Australopithecus which was ever found. Lucy was approximately 40% complete fossil. It was found that her brain size was smaller than today's man but she was bipedalism. She was a new species of Australopithecus- Australopithecus afarensis. So the right answer is D.
Proteins, carbohydrates, and fats all contain three main elements <em>carbon, hydrogen, and oxygen.</em>
However proteins contain nitrogen, and element not found in carbs or fats.
