Answer #1

UV blocking protective eyewear protects against ultraviolet radiation,while providing optimum contrast in viewing and lessening eye fatigue .When you don't view your gel on UV illuminator by these eyewear there is a chance of risk at loosing your eyesight and some other radiations exposure to the skin .

5) We expect only a single band because sometimes the other band is due to nonspecific amplification which is against our experiments

6)The manipulated genes are developed in a special cells known as totipotent stem cells ,cells containing desired DNA are incorporated into the hosts embryo , resulting in a chimeric animal. Unlike the other methods,where we require live transgenic offspring but through this embryonic cell transfer can be tested

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...

What Happens When Hospitals Run out of Ventilators and Other Emergency Rescue Equipment? Patricia Benner, R.N., Ph.D., FAAN April 7, 2020 Our overwhelmed, or soon to be overwhelmed hospitals, face rationing precious life-saving equipment, such as ventilators. Our national lack of preparedness for a global pandemic will, in the near future, force local physicians and nurses to ration ventilators and oxygen delivery equipment, for patients and Personal Protective Equipment (PPE) for caregivers. How do health care providers make decisions about...
