Answer 1

1. Which of the following types of cells are antigen-presenting cells? :-

The right option is (b) Dendritic cells and (c) Macrophages

Explanation: Antigen-presenting cells (APCs) are a group of immune cells that process and present antigen to T cells (another type of immune cells). Classical APCs are dendritic cells, macrophages, Langerhans cells and B cells.

All lymphocytes such as NK cell, B cell are not APCs so option (a) is wrong.

RBCs are also not APCs.

2. In the early 1930’s a procedure to detect cancer of the uterine cervix was first introduced by:

The right option is (a) George Papanicolaou

Explanation: In 1923, New York pathologist Dr. George Nicholas Papanicolaou developed a diagnostic approach that was named Pap smear.

3. The goal of adjuvant treatment is to:

The right option is (b) Kills nay cancer cells remaining after primary treatment
