Sites within the human genome where a short nucleotide sequence is repeated many times in a row are known as short tandem repeats.
DNA sequences with 2 to 6 base pairs are known as short tandem repeats (STRs), and they are dispersed throughout the genome. Multiple repetitions of these brief sequences are possible, and the number of repetitions varies greatly between people. The capacity to distinguish one sample from another is made possible by the great variability.
The Y-STR method's primary benefit is its capacity to identify the male component even in severe male-to-female DNA mixes. The number of semen donors for combinations of two or more male persons can be determined using it, as well as for quickly screening a large number of stains.
Due to their occasionally poor biostatistical efficiency and the potential to detect one or more genetic discrepancies that might potentially be explained by mutational events, STRs have a few drawbacks when examining genetic links in deficient cases.

Answer:
b.)False
Explanation:
In the text given, it explains that Dustin got a threatening message online and didn't seem fazed by it. His friend, Carter should NOT respect his privacy when it is a potentially dangerous event. Even though, Dustin seems as if he doesn't care, he is probably worried still. Therefore, if Carter were to investigate more, hopefully he would be able to help Devin in this situation.
Challenging behavior is the correct answer.
Challenging behavior is defined as any behavior that interferes with children's learning, development and successful play. This type of behavior affects not only the kid who is presenting this behavior but the other kids and adults around him/her. Unfortunately, if this behavior is not dealt with, it will put the child at high-risk, school and social failures later on since it limits the kid's ability to learn and grow.
