Question

a eukaryotic organism utilizes an asexual method to replace millions of cells that were damaged due to a severe burn. which key characteristic applies to the new cells created to heal the wound?
they are diploid cells genetically identical to the original cells.
they are haploid cells destined for reproduction.
they will be genetically diverse due to crossing over.
they are formed after two successive cell divisions.
a researcher analyzes the products of a cell division. the resulting two daughter cells are diploid (2n) and carry the exact same genetic blueprint as the parent cell. this outcome is characteristic of which process?
mitosis, as used in growth and repair.
meiosis, as used in gamete production.
independent assortment, during meiosis i.
crossing over, during meiosis i.

Explanation:

1. When a eukaryotic organism replaces damaged cells via asexual means (like mitosis), the new cells are diploid (as body cells are diploid in most eukaryotes) and genetically identical to the original cells. Haploid cells (for reproduction) are formed via meiosis. Crossing - over occurs in meiosis (not in asexual cell replacement for wound healing). And two successive cell divisions occur in meiosis (not in this asexual replacement).
2. Mitosis results in two diploid daughter cells with the same genetic blueprint as the parent cell. It is used for growth and repair. Meiosis results in haploid cells (for gamete production). Independent assortment and crossing - over are events that occur during meiosis (not the overall process that gives two diploid, genetically identical cells as described).

Answer:

1. A. They are diploid cells genetically identical to the original cells.
2. A. Mitosis, as used in growth and repair.
