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.

Answer:
D). Choice 2 and 3
Explanation:
Given the options above, the limiting factors are both the "Amount of water in the lake" and the "Temperature of the lake"
This is because the amount of water in the lake can only carry as much of the number of fishes as possible it can contain or sustain. This implies that the higher the water content in the lake the higher the number of fishes it can contain and vice versa.
Also, the temperature of the lake is a limiting factor because the temperature of the lake supports the light penetration to the fishes in the water. Should the temperature increases beyond the highest level the water can support, the fishes will die.
