Two facts about cells are: Fact 1: If the parent cell is haploid (n), the daughter cells will also be haploid. If the parent cel
l is diploid (2n), the daughter cells will also be diploid. Fact 2: Single parent diploid (2n) cell produces four haploid (n) daughter cells. Which of these CORRECTLY identifies the two facts? A) Fact 1: meiosis, Fact 2: mitosis B) Fact 1: mitosis, Fact 2: meiosis C) Fact 1: crossing over, Fact 2: meiosis D) Fact 1: genetic recombination, Fact 2: mitosis
First eliminate choices C and D since they both mention that fact 1 is crossing over ( which is also referred to as genetic recombination) . So you're left with A and B and the correct answer is B .
Answer: The correct answer is- B) Fact 1: mitosis, Fact 2: meiosis.
Mitosis and meiosis are the two types of cell division. In mitosis, a parent cell produces identical two daughter cells ( through a series of five stages) having same number of chromosomes as the parent cell. It is called equatorial cell division.
Meiosis is a type of cell division ( occurs in sexually reproducing organism) in which a diploid parent cell produces four haploid sex cells ( reproductive cells such as eggs and sperms) having half the number of chromosomes to that of their parent cell. Thus, it is called reductional division.
Therefore, the given two facts in this question correspond to option B).
Identity moratorium is the third identity status in Marcias theory. This identity represents a high exploration of different things or skill but low commitment to all of them. This is stage of identity crisis in youth. They have tried out different things but are not yet certain of a career type.
