I believe it is the ascending loop of henle. In the ascending portion, the loop becomes impermeable to water and instead the cells of the loop, actively reabsorb the solute; thus water is not reabsorbed but ions are readily reabsorbed. As the ions are reabsorbed the concentration becomes more and more hypotonic until it reaches 100-150 mOsm/L. Therefore, the ascending loop is called the diluting segment of the nephron due to its ability to dilute the fluid in the loop from 1200 to 100 mOsm/L.

The description is provided in the explanation section below
Explanation:
ALTERNATION OF GENERATIONS is a unique phenomenon whereby certain organisms switch between a diploid state and a haploid state in their reproductive life cycle. It is a feature of plants (higher and lower).
A plant is a diploid organism (2n) i.e. contains two set of chromosomes. This diploid state of the plant is called the SPOROPHYTE. The diploid sporophyte (2n) of a plant undergoes meiotic division (reduction division) to produce haploid spores. These haploid spores germinates and grows via mitosis (duplication division) to form the haploid GAMETOPHYTE.
The haploid gametophyte (n), via structures called GAMENTAGIA, produces haploid gametes. The male gametophyte produces male gametes (sperm) while the female gametophyte produces female gamete (egg). These haploid gametes eventually fuse in a process called FERTILIZATION to produce a diploid ZYGOTE (2n) i.e. sperm (n) + egg (n) = zygote (2n). The ZYGOTE undergoes series of mitotic divisions (growth) to form the diploid SPOROPHYTE (2n) of the plant. The cycle restarts again in that order, hence it is called ALTERNATION OF GENERATIONS.
N.B: Mitosis maintains the number of chromosomes of the parent cell while meiosis reduces the chromosomal number of the parent cell by half.
Anti-parallel DNA strands refer to those DNA molecules which contain 2 DNA strands that were held together by hydrogen. In cases that the DNA strands are not anti-parallel the non-symmetrical hydrogen bond will not be possible and will cause some issues.
If I was going to make a prediction for a scientific data thing I would always go to plotting it as a graph – with graphics calculators you can get it to even give you an equation to follow.
The only problem with this is if you're wanting to predict data beyond the range of your given data points (extrapolating), because it is generally viewed as inaccurate.
