Answer:
The role of CFTR is to build channels on the cell surface to enable the flow of chloride (Cl-). When the CFTR protein works properly, the balance of Cl-and fluid at the cell surface is normal. If the mutation of CFTR protein happens the balance of Cl- and fluids is disrupted, causing mucus in various organs to become thick and gluey. As a result, lung infections and, eventually, respiratory failure in the lungs might occur. Mutations on the CFTR normally change single amino acids in the CFTR protein which happens in abnormal channel breaks down soon after it is made.
Explanation:
The CFTR gene gives direction for producing a protein called the cystic fibrosis trans membrane conductance regulator. This protein functions being a channel over the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.The channel transports negatively filled particles called chloride ions into and out of cells.The transport of chloride ions improves control the movement of water in tissues, which is essential for the creation of thin, freely flowing mucus. Mucus is a slippery substance that greases and defends the lining of the airways, digestive system, reproductive system, and different organs and tissues.The CFTR protein further regulates the role of other channels, such as those that transport positively charged particles called sodium ions across cell membranes. These channels are essential for the normal function of organs such as the lungs and pancreas.
The answer is the cell membrane choice C.
Answer is: for one molecule of glucose consumed. two Krebs cycle is needed.

The right option is; c. a salinity of less than 1%
Freshwater biomes have a salinity of less than 1%
The freshwater biome is a large community of plant and animals that live in water bodies with a salinity of less than 1%. Fresh water biomes include streams, rivers, ponds, lakes, and some wetlands. The fresh water biomes cover about 20% of the earth and they contain several species of fish and animals such as frogs, crocodiles and turtles.
