EOC Review Packet #3

Biomolecules Comparison Chart Organic molecules are based on CARBON.
Use the chart in the packet comparing the following biomolecules in the venn diagrams:
3
Carbohydrates & Lipids
SUGARS, STARCHES, CELLULOSE CHITIN Fats, oils, phospholipidswaxes and Steroids CHO Used for energy and structure ENERGY Used for cell membranes
4
Nucleic Acids & Proteins
CHONPS DNA & RNA Store and transmit genetic information Amino acids Enzymes CHON Used to build and repair CHONP

Label these Structures
Nucleotide/Nucleic Acid Amino Acid/Protein Monosaccharide/carbohydrate Triglyceride/Lipid

3 Protein to amino acids
11
2 They are complex molecules made from smaller molecules.
12
Which compounds present in insects are composed of the amino acids that provide the Venus flytrap and sundew with much of their nitrogen? A. Proteins C. Sugars B. Carbohydrates D.fats

14
Identify the stages of Mitosis
A. Prophase B. Metaphase C. Anaphase D. Telophase E. Cytokinesis Mitosis produces two daughter cells identical to both each other and the parent cell due to the complementary rule.
15
Describe what is happening at each phase of the cell cycle
G1 – cell performs regular processes. If the cell gets too large, then… S – DNA replicates G2 – cell gets ready to divide Mitosis – nuclear division Cytokinesis – divison of the cytoplasm
16
DNA Replication Nucleotide DNA strand New DNA strand
Semiconservative Model of DNA replication shows that each new DNA molecule has one original and one new strand due to original strand serving as a template for the new strand (complementary rule). B C
17
Protein Synthesis Describe the purpose and process of transcription and translation. Transcription – a copy of the gene is coded in mRNA Translation – the mRNA is read by the ribosome and a protein is made.

Genetics – Punnett Squares
21
MEIOSIS: Explain why there is only half the number of chromosomes in the resulting gametes: Reduction division – the cell goes through 2 rounds of division. DNA doesn’t replicate before the 2nd round so by the end the number of chromosomes is reduced by half.
22
Genetic Recombination
Examine the process of genetic recombination which occurs during prophase I of meiosis. In your own words explain what and how recombination occurs. Chromosomes cross over and pieces break off and combine with the homologous chromosome. How does genetic recombination lead to diversity within a species population? Mixes up the genes on the chromosomes into new combinations.

Modern Genetics: Meiosis Karyotype
What is the name of the figure to the right? What is the name of the abnormality in the circle? Karyotype During which process did this abnormality result in, mitosis or meiosis? Meiosis How did this abnormality occur? Nondisjunction (failure of chromosomes to separate during meiosis I or II)
27
2 because it matches the crime scene DNA.
What is the name of the figure to the left? DNA fingerprint How is this figure used? Identifies individual since each DNA fingerprint is unique to that individual (exception is identical twins) Which suspect left the DNA at the crime scene? How do you know? 2 because it matches the crime scene DNA.
28
50/50 chance each conception
What is the name of the figure to the left? Pedigree Are the males carriers of this disease or is it passed on to them? Can’t be carriers; passed on Explain how this is a x-linked disease: Males have the disorder because they only inherit 1 X chromosome. Why did only one son become affected and the other did not? 50/50 chance each conception

Types of Mutations: Identify as deletion, inversion, duplication, or translocation

32
Explain how adaptive radiation is a mechanism of natural selection:
Environment favors phenotypes that give organisms an advantage. Those best adapted to the environment survive to reproduce passing on their genes to the next generation Each generation better adapted to the environment then the one before. EVOLUTION
33
homologous Compare homologous to analogous structures.
Analogous – no recent closely related relative. Different structure, same function. Homologous - recent closely related relative. Same structure , different function. Which structures share a recent closely related ancestor? homologous
34
How does embryological evidence support the theory of evolution?
Right after conception, all vertebrates start out looking very similar. The more closely related, the longer they look alike.

What is occurring in each graph?
1. Either end of the spectrum is favored. 2. The mid-range of the spectrum is favored. 3. The range of the spectrum shifted from smallest to the largest.

From the following list of common and Latinized names determine which pair represents the two most closely related plants. broad bean Vicia faba castor bean Ricinus communis kidney bean Phaseolus vulgaris potato bean Apios americana scarlet runner bean Phaseolus coccineus broad bean and castor bean castor bean and kidney bean kidney bean and scarlet runner bean scarlet runner bean and castor bean potato bean and broad bean C

Identify the names of the two norns below by using the dichotomous key to the left.
Dichotomous Key on Norns 1. Has pointed ears go to Has rounded ears go to 2 2. Has no tail Kentuckyus ....Has tail Dakotus 3. Ears point upward go to Ears point downward go to 4 4. Engages in waving behavior Dallus ....Has hairy tufts on ears Californius 5. Engages in waving behavior WalaWala ....Does not engage in waving behavior go to 6 6. Has hair on head Beverlus ....Has no hair on head (may have ear tufts) go to 7 7. Has a tail Yorkio ....Has no tail, aggressive Rajus Beverlus Dallus
41
Describe how viruses and bacteria are similar:
42
Describe the importance of antibiotic treatment and the failure of its effectiveness: Antibiotics kill bacteria but overuse leads to antibiotic resistance in bacteria. How is this similar to chemical pesticide resistance in plants? Same thing happens with pesticides and insects. How does resistance to treatment affect particular populations in terms of survival of the fittest and species continuation or depletion? Those best adapted survive to reproduce - Leads to resistant strains of bacteria.
