Answer:
Nitrogen ---- formed due to the transformation of ammonia (NH3)
carbon dioxide and water vapor ----- released into the atmosphere during volcanic eruptions
helium ------ mostly escaped Earth's atmosphere due to it is light mass.
Explanation:
Nitrogen are formed due to the transformation of ammonia (NH3) due to action of beneficial nitrogen, carbon dioxide and water vapor are released into the atmosphere during volcanic eruptions and helium mostly escaped Earth's atmosphere due to it is light mass. Helium has atomic mass i.e. 2 which is second lowest after hydrogen mass so due to its lighter weight it can't be stay in the atmosphere near to earth.
Inflammatory bowel disease is condition that involves chronic inflammation in a portion or all parts of the digestive tract. It is often painful and debilitating which can be life-threatening and may lead to risk for colon cancer. With inflammatory bowel disease, the small and large intestines or bowels become inflamed (there is redness or swelling).
Its symptoms include: severe or chronic abdominal pain, diarrhea, sudden weight loss, lack of appetite or rectal bleeding.
It has two major types the ulcerative colitis and Crohn's disease. The primary difference between the two is the parts of the digestive tracts that they affect. Ulcerative colitis causes inflammation and ulcers only the top layer of the large intestine. Whereas, Crohn's disease commonly affects the end of the small intestine (ileum) and the proximal part of the colon. Such inflammation causes swelling and scar tissue that thickens the intestinal wall.
Answer:
When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.
