Answer:
D. 0.5 ft
Explanation:
Using the scale :
1 : 4000
This means that an altitude of 4000 feets is represented by 1 unit in the model.
Hence,
1 feet in model = 4000 feet actual altitude
Given an actual altitude of 2000 feets above ground level ;
Feets in the model will be x
1 feet = 4000 feet
x = 2000 feet
Cross multiply :
4000x = 2000
Divide both side by 4000
4000x / 4000 = 2000/4000
x = 0.5
Hence, 2000 feets above ground level corresponds to 0.5 feets in model

Although tube worms cannot produce their own food, they often thrive around these underwater vents. They are able to survive because inside the tube is the trophosome, an organ that contains millions of bacteria in symbiotic relationship with the worm, which are responsible for feeding these creatures that do not have any type of digestive system or visual organs, as they live in the most absolute darkness.
