Answer to Question 1

ANS: B
Energy that is stored or possessed by an object because of its position is called potential energy. Mechanical energy can be divided into either kinetic energy or potential energy. Chemical poten-tial energy often refers to the bonds in petroleum oils that, if broken, can be converted to kinetic energy.

Answer to Question 2

ANS: A
Kinetic energy = (mass of object  square of velocity it is traveling, or mv2) or KE = (V  V). If the velocity is reduced by half, then KE = (V  V), or () = reduction.

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.
