Working down mate, my best answer would be carbon monoxide, but I'm not studying exactly what you are.  All those answers are logical except ozone.

The main function of the small intestine is nutrient absorption. Which of the following structural qualities of the intestine in
Bogdan [553]

Answer:

The correct answer will be option a and b.

Explanation:

The food is digested and absorbed in the small intestine, a long folded tube which lengths about 20 ft or 6m.  

The small intestine increases the surface area for food absorption as they have circular folding as well as the finger-like projections called villi and microvilli in the lumen of the intestine. These villi help in absorption of the nutrients from the intestine.

Thus, option a and b are the correct options.

kari74 [83]

George Monbiot is spearheading the Rewilding Movement. The environmentalist and writer is prominent in the platform. He was featured in TED Talk and talked about a large scale conservation approach aiming to restore the lost habitats. Here is an excerpt of his speech where he discusses the lost megafuna:

"What megafauna, you say? Well, every continent had one, apart from Antarctica. When Trafalgar Square in London was excavated, the river gravels there were found to be stuffed with the bones of hippopotamus, rhinos, elephants, hyenas, lions. Yes, ladies and gentlemen, there were lions in Trafalgar Square long before Nelson's Column was built. All these species lived here in the last interglacial period, when temperatures were pretty similar to our own. It's not climate, largely, which has got rid of the world's megafaunas. It's pressure from the human population hunting and destroying their habitats which has done so."

During extended, intense exercise, a person begins to tire and breathe heavily. If this person continues to exercise, his muscle
Leno4ka [110]

Usually during exercise, unlike during rest times the muscle cells need to respire more. So they need more oxygen and glucose for energy and the carbon-dioxide produced as waste must be removed quickly. So when person gets tired or breathes heavily during intensive workouts means they are in need of more oxygen. So the cells starts performing anaerobic(lactic acid ) respiration even though it releases less energy.
