Answer:
d. differentiation
Explanation:
Developmental potential refers to the ability of a cell to form other cell types. A cell may retain the ability to form other cell types or become specialized to perform specific functions. The process of specialization of cells into specific cell types generally limits their ability to form all cell types and is called differentiation.
For example, differentiation of RBCs include loss of organelles and making space for hemoglobin protein. Mature RBCs loose nucleus and can not divide at all.

Answer:
The presence of an additional chromosome
Explanation:
Look at "pair" 21. See how there are THREE chromosomes instead of TWO? Normally, there would only be two chromosomes in each pair but this karyotype shows a trisomy (see def. below) of the 21st pair. This was caused by a nondisjunction mutation of the 21st pair. The is also the karyotype of a person with Down's Syndrome.
Definition of Trisomy:
A condition of the presence of three chromosomes in a pair instead of two. This normally causes developmental irregularity.
Answer:
Patterns can occur within one species of organism or across many species. Students who understand the concepts can: Use graphs, charts, and images to identify patterns within the fossil record. Analyze and interpret data within the fossil record to determine similarities and differences in findings.
