Explanation / Answer

1. "b" covalent bonds involve sharing of an electron pair between 2 or more than two atoms.

2. "a"

3 ."d"

4. "a" This will be an observation in 2016 as this experiment disproved the idea of spontaneous generation way back long in 1668. so now in 2016 it will just be an observation

5. "c" The taxonomy is kingdom>phylum>class>order>family>genus>species . So the least variety would be in species

6. "d" As kingdom comes at the top of the taxonomy it would be most inclusive

7."a"

9. "c" genome consists all the genetic material coding as well as noncoding sections

10. "a"

11 ."b"

12 "b"

14 "c"
