Answer to Question 1

High-energy jets appear to be the result of matter flowing into a supermassive black hole in the nucleus of an active galaxy. Conservation of angular momentum forces the matter to form a whirling accretion disk around the black hole. How that produces jets shooting away perpendicular to the disk is not entirely understood, but it appears to involve magnetic fields that are drawn into the accretion disk and become tightly coiled, storing energy sufficient to eject high-temperature gas. The twisted magnetic field confines the jets in a narrow beam and causes synchrotron radiation.

Answer to Question 2

False

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

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.
