Though not all tumors or polyps bleed, occult blood in the stool may be an indication of colon cancer or polyps in the colon or rectum.
<h3>What causes occult blood in stool the most frequently?</h3>
Small bowel tumors, esophagitis, peptic ulcers, gastritis, inflammatory bowel disease, vascular ectasias, portal hypertensive gastropathy, and colon cancer are a few of the more prevalent causes (eg, GI stromal cell tumor, lymphoma, carcinoid, adenocarcinoma, or polyp)
If the fecal occult blood test results are positive, blood has been discovered in the stool. Your doctor will need to identify the cause of the bleeding, either by doing a colonoscopy or by performing an examination to establish if the stomach or small intestine is the source of the bleeding.

Explanation:
i think those are the 3
- Rough Endoplasmic Reticulum.
- Chloroplast.
- Cell wall.
- Mitochondria.
- Vacuole.
- Membrane
- Golgi Apparatus.
- Nucleus
- Nucleolus.
The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
- Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.
- Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.
- Cell wall: it is only present in plant cells. It surrounds the membrane.
- Mitochondria: It is the place that generates the energy that the cell needs.
- Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.
- Membrane: it draws the limits of the cell.
- Golgi Apparatus: it is the place where proteins go to be distributed.
- Nucleus: it contains DNA, and it has a membrane around it.
- The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.
To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.
