Answer:
ligament of Treitz
Explanation:
On the basis of anatomy and functions, the small intestine is divided into duodenum, jejunum, and ileum. Duodenum is the first part of the small intestine that starts at the pyrolic sphincter and ends at the suspensory ligament of Treitz. Beyond the suspensory ligament of Treitz, jejunum, and ileum are present without any anatomical distinction to delineate them from each other. Also known as suspensory ligament of the duodenum, the ligament of Treitz is a thin band of muscle and holds duodenum and jejunum in place.

Despite their seemingly simple anatomy and radial symmetry Sea urchins and sea star are a type of deuterostome, closely related to the chordates.
What are the characteristics of deuterostome?
Animals classified as deuterostomes share a common embryonic development.
The first opening during development known as the blastopore changes to the anus in deuterostomes while the mouth changes in protostomes.
They have a coelom, which forms as a result of enterocele (coelom from the digestive tract).
These creatures include the following,
- Chordata,
- Echinodermata,
- Hemichordata.
Hence the correct answer is Deuterostome.

Answer:
Animals and Plants
Explanation:
Biotic means life. Animals and plants are living things. Therefore this is the correct answer.
Answer:
The behavior of chromosomes during meiosis and fertilization is responsible for most of the variation that arises each generation during sexual reproduction. Independent assortment of chromosomes contributes to genetic variability due to the random orientation of tetrads at the metaphase plate. or Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I .
