- 6. the hypothesis that life arises from nonliving matter
- 7. consists of 2 monosaccharides joined by a covalent bond called a glycosidic bond
- 12. formed by an attraction between 2 different atojms that are more significantly different in electronegativity than thoses atoms in polar covalent bonds
- 14. population of cells derived from a single parent cell
- 15. the hypothesis that living cells aires only from preexisting living cells
- 17. found between electrons of the same element becuse they are shared equally

- 25. who reported that living things are composed of little boxes, or "cells"
- 26. genetically different cells within clone, arising usually due to mutations
Down
- 1. found between electrons of different elements because they are not always shared equally
- 2. gram staining, acid-fast staining
- 4. hydrolysis is an example of what
- 5. the simple sugars (monomers)
- 8. are found between molecules, not within them
- 9. bacteria agglutinate (clump) when mixed with antibodies produced in response to the bacteria
- 10. a population of cells with a high degree of genomic similarity
- 11. the smallest unit of matter that still retains the properties of an element
- 13. can differentiate between species and strains within species
- 16. the sharing of electrons between 2 or more atoma to form a molecule or compounds
- 18. useful for identifying eukaryotes, but tells little about phylogenetic relationships
- 20. adds water to break down polymers into their component monomers
- 21. the science of classifying organisms
