Question10 Bile acids are important compounds secreted by your liver to aid in digestion of fat molecules. Bile acids consist of a polar head group and a nonpolar tail group, allowing them to surround fat droplets in your intestine during digestion and help make the fats soluble in the hydrophilic intestinal environment so that they can be digested. Which of the diagrams below represent the configuration of bile acids as they surround a droplet of fat in your intestine? (Note: each of these images is a cross-section of a sphere)

helicase, i think thats it

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
