Answer:
Alpha feto protein AFP
Explanation:
Plasma protein bio marker alpha feto protein is detected by the liver test to determine the presence of liver cancer in a patient.
High levels of alpha feto proteins is also a sign of cancer of ovaries and testicles and also liver non cancerous diseases that is cirrhosis and hepatitis.
The increased levels of two liver enzyme AST and ALT is also indicator of hepatic cancer.
The answer is "A" because Na = 22.9 and O =16 so it is 22.9*2+16
The charges on a droplet can be used to represent the number of electrons carried by this droplet.
In other words:
a droplet having a charge of 1.60 x 10^-19 has 1.60 x 10^-19 electrons while a droplet having a charge of 3.15 x 10^-19 has <span>3.15 x 10^-19 electrons.
From the observations:
The fact that the droplets carried different charges signifies the fact the different droplets carried different numbers of electrons</span>
