Explanation / Answer

Q.1

Answer: Stem cells

Explanation: They can differentiate into any type of cells in our body.

Q.2

Answer: Stem cells

Explanation: Due to ethical issue they are lot of controversies in medical use.

Q.3

Answer: Specialized cells

Explanation: Once the stem cell is differentiated into specialized cells, they have a specific function only.

Q.4

Answer: Stem cells

Explanation: Morula are considered as totipotent stem cells. They are obtained by the fusion of sperm to an oocyte.

Q.5

Answer: Specialized cells

Explanation: Once the stem cell is differentiated into specialized cells, they have a specific function only.

Q.6

Answer: Stem cells

Explanation: Embryonic stem cells are pluripotent stem cells while morula are considered as totipotent stem cells.

Q.7

Answer: Specialized cells

Explanation: Cardiac stem cells are specialized stem cells. Once the stem cell is differentiated into specialized cells, they have a specific function only.

Q.8

Answer: Specialized cells

Explanation: Mitosis is a process where the specialized cell divides and makes a copy of itself.

Q.9

Answer: Cell division

Explanation: Mitosis is a process where the cell divides and makes a copy of itself.

Q.10

Answer: Option C

Explanation: Embryonic stem cells are pluripotent stem cells while morula are considered as totipotent stem cells.

Q.11

Answer: Option B

Explanation: Epigenetic factor regulates the expression of gene in a cell. They are responsible for turning off and on of a gene in a cell.

Q.12

Answer: Option A

Explanation: Human --> Digestive system --> Stomach --> Epithelium --> Oxyntic cells.

Q.13

Answer: Option B

Explanation: Photo 51 is an X-ray crystallography picture which revealed the structure of DNA.
