What is the relationship between atomic mass and mass number?
They are the same.
Atomic mass is always greater than mass number.
Atomic mass and mass number are not related.
Atomic mass is very close to mass number but with some deviation in the decimal places.
The Correct Answer is D
Atomic mass is very close to mass number but with some deviation in the decimal places.
Atomic mass is also known as atomic weight and is the weighted average mass of an atom of an element based on the relative natural abundance of that element’s isotopes.
The mass number, on the other hand, is a count of the total number of protons and neutrons in an atom’s nucleus.
Choice A is incorrect because atomic mass and mass number do not mean the same thing.
Choice B is incorrect because atomic mass is not always greater than mass number.
Choice C is incorrect because atomic mass and mass number are related.

Choice B is incorrect because archaea reproduce by fission, fragmentation, or budding, while bacteria can produce spores and divide sexually or asexually. Choice D is incorrect because archaeal and bacterial flagella are constructed differently.
Correct Answer is A
Explanation
The terminal velocity of an object falling through a fluid is affected by several factors, including its mass and shape.
Objects with large surface areas will often experience a large amount of air resistance when they move.
Choice B is incorrect because the volume of the object does not affect its terminal velocity.
Choice C is incorrect because the acceleration and momentum of the object do not affect its terminal velocity.
Choice D is incorrect because the height and distance of the fall do not affect the terminal velocity of a falling object.
