question 12

Multiple Choice

In vacuum, the components of an EM wave are E_y = (50 V/m) cos [(5.0 m⁻¹) x + ωt], E_x = 0, and E_z = 0. What is the amplitude of the magnetic field for this wave?

• B) 1.67 × 10⁻⁷ T
• C) 2.00 × 10⁻⁷ T
• D) 1.50 × 10⁻⁶ T
• E) 1.33 × 10⁻⁶ T

Explain the concept of genotype, allele frequencies, and the Hardy-Weinberg equilibrium in populations.

Identify factors that cause deviations from Hardy-Weinberg equilibrium and their implications for population genetics.

Examine how gene flow and genetic drift contribute to the genetic makeup of populations.

Calculate allele, genotype, and heterozygote frequencies within populations.

Definitions:

Mitral Regurgitation

A condition in which the heart's mitral valve does not close properly, allowing blood to flow backward into the left atrium when the left ventricle contracts.

Mitral Stenosis

A heart valve disorder that involves the narrowing of the mitral valve, leading to restricted blood flow from the left atrium to the left ventricle.

Aortic Regurgitation

A heart condition where the aortic valve does not close properly, causing blood to flow backward into the heart.

Cardiomyopathy

A disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body.
