Why don't the remora fishes get eaten by the shark when they are attached to the shark?

Which are the best units to measure the capacity of a shark tank...square meters or cubic meters?

Cubic meters are the best unit to measure the capacity of a shark tank because volume measurements like cubic meters can accurately represent the three-dimensional space inside the tank. Square meters measure area, not volume, and would not provide an accurate representation of the tank's capacity.

Why when you smell something does the smell go away after a while?

It is practical in life. The opposite would be very unpractical. Say you are a bear, you excrete your feces in your cave and you would not cease to smell your smells - you would not easily smell e.g. a scent of some threat (lets say a pack of hyenas), or you would not smell other bear which you could mate with, for example.

Why are there shark teeth fossils in the mountain of NC?

Shark teeth fossils found in the mountains of North Carolina are a result of the area being underwater millions of years ago.

The shark teeth fossils are evidence of the region's geological history and ancient marine ecosystems.

Do sharks nurse or abandon their offspring?

To my knowledge, Sharks do not nurse their offspring and while they my hover around until just after birth, they genereally abondon their young after they are born leaving them with a food source for the young to eat until they've learned to hunt for themselves.

Where is the most anaerobic zone in the ocean?

The most anaerobic zone in the ocean is found in the waters near the seafloor in regions known as oxygen minimum zones (OMZs). These areas have very low levels of dissolved oxygen, making them suitable habitats for anaerobic organisms. OMZs are often located in deep ocean basins or along coastlines where oxygen supply is limited.
