AX + B BX + A = Single Displacement 3. AX + BY AY + BX = Double Displacement 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 100 All of the following are true of both magnetism & electricity EXCEPT: a. Like poles & charges repel; opposites attract. b. The strength of attraction & repulsion of electric charges or magnetic poles vary inversely as the square of the distance between the charges or poles. c. It is possible to isolate a single positive or negative electric charge or a single north or south magnetic pole. d. The forces of attraction or repulsion between two magnetic poles on either pole, or between two electric charges on either charge are of equal strength. 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 100 ANSWERS C Magnetism differs from electricity in that a single positive or negative electron charge can be isolated, but magnetic poles cannot 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 200 In which direction will a compass point if it is held directly over a wire carrying a strong current? a. North b. South c. Perpendicular to the wire d. Parallel to the wire 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 200 ANSWERS C The magnetic field created by the wire will go around the wire. The north pole of the compass magnetic field will point against this magnetic field. 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 300 ? 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 300 ANSWERS 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 400 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 400 ANSWERS 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 500 CIRCUITS BELOW HAVE BATTERIES WHICH ALL HAVE THE SAME EMF A) X B) Y C) Z D) All the above are equal 1.Which Circuit has the greatest current? 2.Which of the following provides the most current? 3. Which circuit provides the least light? 1/5/2013 Medical Pathway Program 7 LAWS ACCORDING TO EINSTEIN - 500 ANSWERS 1. C 2. C 3. B 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 100 Define the difference between phenotype and genotype. 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 100 ANSWERS Genotype refers to the genetic makeup of an individual. Phenotype refers to the physical manifestation of an individual’s genotype. 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 200 Summarize Mendel’s First Law (Law of Segregation) 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 200 ANSWERS Mendel’s first law states that alleles segregate during meiosis; specifically: 1. Genes exist in alternative forms (alleles). 2. An individual inherits 2 alleles for each trait, one from each parent. 3. The 2 alleles segregate during meiosis. 4. If 2 different alleles are present, only 1 will be fully expressed. 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 300 There are flowers with a specific characteristics: Given: P = Dominant (Purple) p = recessive (White) What is genotypic ratio of Pp x pp cross? 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 300 ANSWERS Pp x pp 50% Pp : 50% pp 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 400 What is the percentage for daughters to inherit their father’s sex-linked gene? 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 400 ANSWERS 100% of daughters will inherit their father’s sex-linked genes. 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 500 What are the 3 different results of chromosomal breakage? 1/5/2013 Medical Pathway Program 7 THE PERFECT PAIR OF GENES - 500 ANSWERS The three different results of chromosomal breakage: 1. Duplication: the fragment joins with its homologous chromosome. 2. Translocation: The fragment joins with a nonhomologous chromosome. 3. Inversion: The fragment rejoins its original chromosome but in the reverse position. 1/5/2013 Medical Pathway Program 7 NATURALLY & ORGANICALLY MADE - 100 1 1/5/2013 2 Medical Pathway Program 7 3 4 NATURALLY & ORGANICALLY MADE - 100 ANSWERS 1/5/2013 Medical Pathway Program 7 NATURALLY & ORGANICALLY MADE - 200 1/5/2013 Medical Pathway Program 7 NATURALLY & ORGANICALLY MADE - 200 ANSWERS 1/5/2013 Medical Pathway Program 7 NATURALLY & ORGANICALLY MADE - 300 ? 1/5/2013 Medical Pathway Program 7 NATURALLY & ORGANICALLY MADE - 300 ANSWERS 1/5/2013 Medical Pathway Program 7 NATURALLY & ORGANICALLY MADE - 400 1.
