eye is to be one of the fastest hunters of prey on Earth. The twenty two fleshy tentacles attached to the nose of the Star-nosed Mole are incredibly sensitive to touch and aid the mole in capturing prey. Just how beneficial is the snout of a Star-nosed Mole exactly? They could touch a pin head with their nose six hundred times at once. Crazy enough in a single day‚ this mole can consume up to its own body weight in worms and insects. They as well dig tunnels underground and are a valuable aspect to

What mutations are associated with haplogroup H? As the ancestors of haplogroup H migrated from the Middle East to India 45‚000 years ago‚ the mutations that became associated with the haplogroup are M168‚ M89‚ and M69. M69 is also commonly known as the‚ “Indian marker‚” but M69 can also be born in Southern Central Asia. M89 on the other hand first appeared around 45‚000 years ago in northeastern Africa. “In modern day this mutation (marker) is found in more than 90 percent of all non-African men”

factor of H.pylori is the development of gastric adenocarcinoma. H. pylori strains that have the cag pathogenicity island induce more severe gastric injury and further augment the risk for developing cancer of the stomach (13). Iron deficiency enhances H. pylori virulence and represents a measurable biomarker to identify populations of infected persons at high risk for gastric cancer (14) .It can affect extra gastrointestinal organs as H. pylori can infect the skin‚ liver and heart (15).
