Q #1: A represents atomic mass and 2 represents an atomic number, which of the following describes an atom after a proton is emitted?

A. A-1,2-1

B. A-1,2+1

C. A,2-1

D. A+1,2-1

Answer Explanation

This is because when a proton is emitted from an atom, the atomic mass decreases by one unit, and the atomic number decreases by one unit. The atomic mass is the sum of protons and neutrons in the nucleus, and the atomic number is the number of protons in the nucleus. Therefore, if a proton is lost, both numbers decrease by one.
Q #2: The vermiform appendix extends from the region of the large intestine known as which of the following?

Q #3: Which of the following tools can be used to measure the turbidity of a liquid by measuring the transmission of light through the sample?

A. Spectrophotometer

B. Centrifuge

C. Electro photometer

D. Microdensitometer

Answer Explanation

A spectrophotometer is an instrument that measures the intensity of light absorbed after it passes through a sample solution. With the spectrophotometer, the concentration of a chemical substance can be determined by measuring the intensity of light detected.
