Answer:
See the answer below
Explanation:
The modern model of the atom sees it as <u>a small structure with a dense, positively charged core called nucleus</u>. The nucleus houses most of the masses of the atom and consists of the proton and the neutron. The positively charged proton is primarily responsible for the positiveness of the nucleus. At some distance away from the nucleus is a light, negatively charged particle called the electron that revolves around the nucleus in an orbit-like fashion .
For a neutral atom, the number of the positively charged proton balances that of the negatively charged electron which circulate rounds the nucleus. Atoms in which these two particles do not balance each other are no longer described as being neutral.
Then the mice would not be infected as the DNA is destroyed by the enzyme ....so S type have no use and can't transfer it's DNA ....so mice survive !
The evolutionary significance is that coal does not change the properties of the plant from that time even though the plant might have evolved from that time. That's why you can study coal to find out how the type of plant was at that time period and how it has evolved until now.

A distinct and diverse group of Protista is most closely related to
archaebacteria for they are both single celled organism. Protista are broad group of eukaryotes that
includes all eukaryotic organisms that are not plants, animals or fungi. Some scientists believe that
eukaryotes descended directly from archaebacterial and a large number of protists live as parasites of
animals and plants as archaebacteria do.
