This is also known as Avagadro's number. It is an important constant in chemistry and is equal to the number of atoms/molecules found in 12 grams of carbon-12.Answer and Explanation: The atomic mass of oxygen is 15.999 AMU. AMU represents the atomic mass unit. An atomic mass unit is...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
The average atomic mass of oxygen is 15.999 AMU. This value rounds to 16, which indicates that oxygen-16 is the most abundant isotope of oxygen... Learn more about this topic: Average Atomic Mass | Definition, Formula & Calculation from...
Cerebral palsydescribes the condition where a developing infant's brain is deprived of oxygen and fails to develop normally. This may occur in the uterus before birth or may be due to an injury or illness that happens within the first couple of years of life. Often, it is an infection or...

As Earth's magnetic field redirects the particles toward the poles — there are southern lights, too, which you can read about below — they interact with atmospheric gases like oxygen and nitrogen. The result is a glowing light show that appears in waves, curtains or arcs across the sky. ...
inflammatory mechanism(s) for neurological post-COVID-19 manifestations [18]. Neurological manifestations and BBB disruption mechanism(s) are the major complications in long-COVID-19 [19]. The proposed interaction of COVID-19, after entry, within the nervous system tissues, is sketched (Fig.2)...
