Answer:

D) brevity

Explanation:

The key characteristics of a well-designed test includes the following;

I. Standardization: it is important that test is set based on certain criteria and acceptable rules within the education community and curriculum.

<h3>What is chromosomes?</h3>

A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code. Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.

A medical geneticist specializes in using DNA tests and genetic data to identify, manage, or prevent chromosome problems, inherited genetic illnesses, and other genetically driven diseases and ailments.

Orthopedic physicians, often known as orthopedic surgeons, concentrate on assisting you with musculoskeletal problems. They are responsible for identifying and managing diseases that impact your musculoskeletal system.
