Lelechka [254]

Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.

Explanation:

In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.

What function do the alveolar sacs serve in the respiratory system?
Brrunno [24]

These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.

In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.


SHORT ANSWER:

Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.

Which region is directly medial to the hypochondriac regions of the body?
amm1812
The region which is directly medial to the hypochondriac regions of the body is the epigastric region. It is the upper central part of the abdomen, found in between the subcostal plane and the costal margins. This region is part of the nine regions found in the abdomen. The organs included in this region are the pancreas, liver and the stomach. Also, the adrenal gland, a part of the small intestine, the duodenum is also included. This region is not an organ or a muscle rather it is an area of activity wherein the diaphragm and the rectus abdominus would make an outward bulging of the abdominal wall especially the upper portion.

Analysis of stable carbon isotopes in ________ can provide information on ancient diet.
tino4ka555 [31]
<span>The answer is bone. A new technique of observing Harris lines (between the diaphysis and epiphysis of long bones), by use of radiography, of bone is being used to postulate ancient diet of populations. This is especially used to determine stressful periods that were characterized by poor diet (deficiencies) by comparing carbon and nitrogen isotope ratios</span>
