Find out the following from your partner: NAME, GRADE, POST HS PLANS, REASON FOR LIVING Share and Fill in Summer Assessment Answers Share and Fill in Summer Assessment Answers

7 Online Assessment 1. What is the building block of all living organisms B. cells 2. Each element has its own characteristic atom in which B. the atomic number is constant

8 Online Assessment 3.Radioactive isotopes can be used in studies of metabolic pathways because D. their location or quantity can be experimentally determined because of their radioactivity

9 Ex. RNA vs DNA Hershey and Chase

10 Online Assessment 6.A covalent bond between two atoms is likely to be polar if A. one of the atoms is much more electronegative than the other.

11 Water – super important for life Oxygen much more electronegative than Hydrogen so…get a great shape! Oxygen much more electronegative than Hydrogen so…get a great shape!

12 Online Assessment 7.A triple covalent bond would E. involve the sharing of six electrons. 8. A cation D.has a positive charge.

13 Top cation in biology? H+ H+ Hydrogen ion is really just a? Hydrogen ion is really just a? –PROTON

14 Online Assessment 9.The ability of morphine to mimic the effects of the body's endorphins is due to C.molecular shape similarities that allow morphine to bind to endorphin receptors ISOTOPES

16 Online Assessment Online Assessment 16.What type of bond would you expect potassium (K) to form? Atomic # = 19, Atomic Mass = #39 A. ionic; it would donate one electron and carry a positive charge

17 Online Assessment 18. One of the major differences in the cell division of prokaryotic cells compared to eukaryotic cells that D. the chromosomes do not separate along a mitotic spindle in prokaryotic cells

18

19 Online Assessment 19.A plant cell has 12 chromosomes at the end of mitosis. How many chromosomes did it have at the beginning of the cell cycle? C. 12

20

21 Online Assessment 20.How many chromatids would the cell with 12 chromosomes have in the G2 phase of its cell cycle? D. 24

22 Online Assessment 22.Humans have 46 chromosomes. That number of chromosomes will be found in C. the somatic cells

23 Online Assessment 23. Sister chromatids C. each have their own kinetochore 27. The restoration of the diploid chromosome number after halving in meiosis is due to B. fertilization

24

25 Online Assessment 31. In most fungi and some protists, C. the multicellular organism is haploid 32.In the alteration of generations found in plants, B.the gametophyte generation produces gametes by mitosis

26 Online Assessment 38. The classification of organisms into hierarchical groups is called B. taxonomy 39. Darwin proposed that new species evolve from ancestral forms by A. the gradual accumulation of adaptations to changing or different environments

27 Online Assessment 40. The best description of natural selection is C. the reproductive success of the members of a population best adapted to the environment

28 Online Assessment 44. The smallest unit that can evolve is D.a population 50.The DNA of an organism has thymine as 20% of its bases. What percentage of its bases would be guanine? B.30%

29 Online Assessment 55. Transcription involves the transfer of information from A. DNA to RNA A. DNA to RNA 59.The cellular binding site for protein synthesis is E. the ribosome
