Answer: The atom is mostly empty space.
Explanation:
Before to Rutherford, the accepted model for the atom was Thomson's model:
The atoms were a positive sphere, with electrons occupying space in it".
This was called the "plum pudding model".
Then came Ernest Rutherford, and he created a model where the atoms are mostly empty space (void) with a positive charged nucleus (really compressed in the center), and the electrons were orbiting around it.
Then the correct option is that the atom is mostly empty space.
Answer:
prokaryotic cells do not have a nucleus or membrane bound organelles.They also have small rings of double-stranded extra-chromosomal DNA called plasmids.
Because human DNA is so very long (with up to 80 million base pairs in a chromosome) it unzips at multiple places along its length so that the replication process is going on simultaneously and more accurately.
