Answer to Question 1

4

Answer to Question 2

A negative charge is placed on an electroscope by induction when a glass rod rubbed
with a silk cloth is used to charge the rod. A glass rod, when rubbed with a silk cloth,
will possess a positive charge. When the positive charged rod is placed near the knob
of the electroscope, electrons will be attracted to the knob. While holding the charged
rod near the knob, touch the knob with your finger. Electrons will flow from your
body to the electroscope. Remove your finger from the electroscope. The electrons
have no conducting path to leave the electroscope. Thus, the electroscope retains an
excess of electrons and a negative charge.

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.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Nearly all drugs pass into human breast milk. How often a drug is taken influences the amount of drug that will pass into the milk. Medications taken 30 to 60 minutes before breastfeeding are likely to be at peak blood levels when the baby is nursing.
