Answer:
To increase the absorption of nutrients into the bloodstream.
Explanation:
The small intestine is the largest organ of the digestive system. It is meant for the absorption of food. The majority of food is absorbed by the small intestine.
For this purpose, the small intestine is long and has villi. These villi increase the surface area of the small intestine which enhances the absorption of nutrients. It directly absorbs into the blood.
The small intestine is also divisible into 3 parts - duodenum, jejunum, and ileum. Most of the absorption happens in jejunum and ileum. In the duodenum, bile mixes with food and break it down.
This is the very reason the small intestine is the longest organ.

Answer:
E) sister chromatids separate during anaphase of meiosis I.
Explanation:
Chromosomes are composed of two chromatids which are joined together through centromere. Chromosomes get doubled its chromatids during its S phase of Interphase. Although chromosomes number remains the same as after S phase but number of chromatids becomes double.
For Example:
In humans 46 chromosomes are present before S phase and 46 chromosomes after S phase. only difference is that chromatids before S phase is 46 in number while after S phase it becomes double i.e becomes 92.
During Prophase 1 of Meiosis 1 these 46 chromosomes with 92 chromatids get arranged in manner that homologous chromosome pair comes close together and form 23 pairs.
During Metaphase 1: These 23 pairs get arranged in center and attached with spindle fiber present inside cells. Each spindle fiber attach to one member of the pair in a manner that 23 spindle fibers from one side of pole attached to one member of homologous chromosome pairs and 23 spindle fibers from other side of pole attached to other member of homologous chromosome pairs.
In Anaphase 1 of Meiosis 1 these spindle fibers get contracted and pulled attached chromosome along with them towards opposite poles. In this manner chromosome numbers in Meiosis become half as compared to the Mitosis
So Correct Answer of the question is
E. sister chromatids separate during anaphase of meiosis I.
