The answer ; double, single
In unsaturated oils, the double bonds cause the hydrocarbon chains to have kinks hence do not allow adjacent hydrocarbon chains to form enough hydrogen bonds between each other. Therefore, chains are not compact enough even at low energetic levels (at room temperature).
In saturated oils, the single-bond hydrocarbon chains have numerous hydrogen bonds between adjacent chains that they become compact at room temperature (when their molecules have low energy levels)
Answer:
inclined plane and lever. advantages they got allowed them to move rocks higher as they built up and to lift heavier objects.
Meiosis I is dedicated to forming two Haploid(half chromosome) cells bby separating each pair of chromosomes (one of each type in each cell) and the recombination, or shuffling of genes on each chromosome with its pair by crossing over, While Meiosis II is meant to split the individual chromatids in the haploid cells to create a total or 4 daughter cells
Hope this helps! :)
The tissue you are referring to here is the xylem, a <u>vascular tissue</u>, whose basic function is to transport water and nutrients from the roots to the rest of the plant.
