Answer:
Kat should get a whistle that emits sounds in the range of <u>23 and 54,000 Hz</u>.
Explanation:
The hearing range is the frequency range that can be heard by the animals, including humans.
Generally, the hearing range of humans is about 20 to 20,000 Hz and the hearing range of dogs is around 67 to 45,000 Hz
Dog whistles are the whistles which emits ultrasonic sound and are used for training dogs. <u>Generally, the dog whistles are within the range of 23 to 54,000 Hz and thus, can not be heard by the humans.</u>
Answer: The most likely result is the production of abnormally sticky mucus that lined the walls of internal organs
Explanation:
The deletion occurring in cystic fibrosis, leads to a defect in the production of a protein called cystic fibrosis transmembrane conductance regulator. This protein functions in the production of body fluids like sweat, tears, and mucus digestive enzymes and saliva. In this production, the movement of chloride ions in and out of cells is important as it controls the movement of water that controls the thinning of the fluids to be produced.
In cystic fibrosis, there is a mutation in the control of production and movement of these chloride ions across cells, resulting also in a lack of movement of water.
This mutation results in the production of abnormally sticky and thick mucus, lining organs such as the lungs. This causes obstruction of secretory glands and airways.
