What is the most common form of panspermia?
-
Directed panspermia
-
Natural panspermia
-
Lithopanspermia
-
Cryopanspermia
B
Correct answer
Explanation
Natural panspermia is the most common form of panspermia, and it proposes that life on Earth was seeded by comets and asteroids that carried organic molecules from other planets or moons.
Which technique involves transferring the nucleus of a somatic cell into an enucleated egg cell?
-
Somatic Cell Nuclear Transfer (SCNT)
-
Induced Pluripotent Stem Cell (iPSC) Generation
-
Transdifferentiation
-
Nuclear Transfer
A
Correct answer
Explanation
Somatic Cell Nuclear Transfer (SCNT) involves transferring the nucleus of a somatic cell into an enucleated egg cell, resulting in the development of an embryo that is genetically identical to the donor of the somatic cell.
Which part of the egg is responsible for fertilization?
-
Yolk
-
Albumen
-
Germinal disc
-
Chalazae
C
Correct answer
Explanation
The germinal disc is a small, white spot on the surface of the yolk where fertilization takes place.

Which of the following is NOT a potential treatment option for infertility in men?
-
Medication to improve sperm quality
-
Surgery to correct anatomical abnormalities
-
In vitro fertilization (IVF)
-
Lifestyle modifications

Correct answer
Explanation
IVF is a fertility treatment typically used for women, not men.
What is the term used to describe the process of fertilizing an egg outside the body?
-
In vitro fertilization (IVF)
-
Intrauterine insemination (IUI)
-
Zygote intrafallopian transfer (ZIFT)
-
Gamete intrafallopian transfer (GIFT)
A
Correct answer
Explanation
IVF involves fertilizing an egg with sperm in a laboratory dish and then transferring the resulting embryo into the uterus.
Which of the following is NOT a type of panspermia?
-
Lithopanspermia
-
Radiopanspermia
-
Cryopanspermia
-
Directed Panspermia
D
Correct answer
Explanation
Directed Panspermia is not a type of panspermia because it involves the intentional spreading of life from one planet to another, while the other options involve the natural transfer of life through various mechanisms.
