Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.

  • Out of the 14 facial bones, the mandible, maxilla, zygomatic and vomer along with the frontal bone are the primary bones of the skull.
  • The rib cage comprises of 12 pairs of ribs connected to the sternum, the main bone that anchors the rib cage, through the costal cartilage.
  • The ribs numbered 1 to 7 are called true ribs because costal cartilage connects these bones directly to the sternum.
  • The ribs 8 to 12 are classified as false ribs because they are not directly connected to the sternum.
  • The last two ribs 11 and 12 are called floating ribs because they do not connect to the sternum at all.
