A point charge +Q is located on the x axis at x = a, and a second point charge -Q is located on the x axis at x = -
 a. A Gaussian surface with radius r = 2a is centered at the origin. The flux through this Gaussian surface is
  a. zero because the negative flux over one hemisphere is equal to the positive flux over the other.
  b. greater than zero.
  c. zero because at every point on the surface the electric field has no component perpendicular to the surface. d. zero because the electric field is zero at every point on the surface. e. none of the above.

Question 2

A point charge is located at the origin. Centered along the x axis is a cylindrical closed surface of radius 10 cm with one end surface located at x = 2 m and the other end surface located at x = 4 m. If the magnitude of the electric flux through the surface at x = 2 m is 4 N  m2/C, what is the magnitude of the electric flux through the surface at x = 4 m?
 a. 1 N  m2/C
  b. 2 N  m2/C
  c. 4 N  m2/C
  d. 16 N  m2/C
  e. The correct value is not given.

Fatal fungal infections may be able to resist newer antifungal drugs. Globally, fungal infections are often fatal due to the lack of access to multiple antifungals, which may be required to be utilized in combination. Single antifungals may not be enough to stop a fungal infection from causing the death of a patient.

IgA antibodies protect body surfaces exposed to outside foreign substances. IgG antibodies are found in all body fluids. IgM antibodies are the first type of antibody made in response to an infection. IgE antibody levels are often high in people with allergies. IgD antibodies are found in tissues lining the abdomen and chest.

The first monoclonal antibodies were made exclusively from mouse cells. Some are now fully human, which means they are likely to be safer and may be more effective than older monoclonal antibodies.
