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.

The conditions on early Earth, some three to four billion years ago, are thought to be much different from what they are today. To begin with, the astronomical phenomenon called “the big bang” is defined by a theory proposing that the earth was one of the larger particles that coalesced after the initial universe explosion, or big bang, that spewed all the particles in the universe away from a central point and destined them to slowly revolve around that point.

Carrying capacity is the paramount number of a particular species that the earth or ecosystem can hold while limiting factors are the biotic and abiotic factors that confines or limits the growth of the living organism.
More the amount of limiting factor, greater will be the number of growth of the organism as the raw materials to hold life would be enough to sustain these many number of organism. Therefore, limiting factor governs the carrying capacity of various organisms on earth.
The gradual abundance of oxygen (by product of photosynthesis) made it possible for aerobic organisms to grow more and evolve.
Hope that helps!
