A set of questions regarding cell division (mitosis and meiosis), digestion, and related biological processes.

Here are the solutions to the questions:

I. True or False

1. S Phase is the state of DNA replication (synthesis).
   • True
2. The Prophase is composed of four other subphases.
   • False
3. Anaphase is the shortest and whole sister chromatids are pulled apart to the poles.
   • True
4. Cytokinesis is the process in which the cytoplasm divides to form two separate daughter cells.
   • True
5. The final product of mitosis is two identical diploid cells.
   • True

II. Choose the correct answer

1. Which one is also reversed prophase?

   • A) Telophase Telophase is considered the reverse of prophase because the nuclear envelope reforms, chromosomes decondense, and the spindle fibers disappear.

2. Which one is a nuclear division?

   • D) All Mitosis and Meiosis are types of nuclear division, and karyokinesis is the process of nuclear division itself.

3. Which one is the removal of food waste from the body?

   • C) Egestion Egestion is the process of eliminating undigested food material (feces) from the body.

4. Which one is a part of the small intestine?

   • D) All The small intestine consists of three parts: the duodenum, jejunum, and ileum.

5. Which one is important to prevent the watery fluid bile to regurgitate?

   • B) Pyloric The pyloric sphincter controls the flow of chyme from the stomach into the duodenum and helps prevent duodenal contents (including bile) from refluxing back into the stomach.

6. Which one is important to prevent the watery fluid chyme to regurgitate?

   • A) Cardiac The cardiac (or lower esophageal) sphincter prevents stomach contents (chyme) from flowing back into the esophagus.

7. The two chromatids are maternal or paternal chromosomes linked to each other by centromere on the centromere.

   • B) Sister chromatids Sister chromatids are identical copies of a chromosome joined together by a centromere, formed after DNA replication.

8. Which one is about protein synthesis extended from the nucleus?

   • C) Ribosomes Protein synthesis occurs on ribosomes, which translate
