Rudiy27

Answer:

The terms old world and the new world are used in the context of history and for the prime objective of differentiating the major ecozones found on the planet. This also helps in categorizing various species of plants and animals that originated in different places and times.  

In terms of old and new, Old World signifies to Asia, Europe, and Africa, on the other hand, the New World signifies towards the Americas that comprise South America, North America, and Central America. The New World monkeys possess prehensile tails, while the Old World monkeys don't. This suggests that the prehensile tail originated in the monkeys found in the New World, primarily after the separation of the Americas from Asia and Africa.

Explain why plants along the road often die after the road is sprayed with a salt solution to melt ice
vovangra [49]

Explanation:

The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.

What is pancreatitis and what is the basic mechanism that underlies the condition?
svp [43]
Pancreatitis is an inflammation of the pancreas that may be caused by years of heavy consumption of alcohol of gall stones. The pancreas plays major important roles such as secreting digestive juices into the small intestines, which help to digest fats, proteins, and the carbohydrates in food. It also release hormones insulin and glucagon that regulate the blood sugar. Pancreatitis is characterized by a pancreas being inflamed, therefore when this happens the body's normal complex coordination is disrupted and the enzymes in the pancreas are prematurely activated before they exit the organ, which results in these enzymes digesting the pancreatic tissue.
