Explanation:
I will have to use motivation as a way of enhancing change in the life of Sally. From this question, she seems to be a lonely lady, with low self-esteem and no physical activity. The first thing I would do is to help to get her out of monotony by motivating her.
Once motivated, I would help plan her diet and add combinations of physical activities. These activities may include walking and running. With time an expert would take over her physical training.
She has to make time for other activities such as yoga or community work. The purpose for this is so she can meet and connect with other people, this would give her a sense of belonging. And would help boost her self image.
In conclusion, Sally needs a combination of physical and emotional therapy in order to change her lifestyle.
Answer:
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
Explanation:
Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR <em>loci</em> which are used in forensic identity testing.
