Solution:

Nitrogen is important because, it helps us grow crops, and it produces grass for animal. It comes from lightning and is named nitrogen fixation

By which free nitrogen (N2) is extracted from the atmosphere and converted (fixed) into nitrogen compounds which are plant nutrients (fertilizer). In nature, this process is carried out by certain bacteria (present in the root nodules of legumes such as beans and peas), blue-green algae, and the lightning flash.

Thus the Nitrogen form the atmosphere the biotic part to the ecosystem converted into the biotic part.

What is the unique structural modification in lymphatic capillaries that increases their permeability?
KonstantinChe [14]

Answer:

Minivalves

Explanation:

Lymphatic capillaries are so much permeable that some researchers thought that they are open from one side but scientists found that this permeability is due to some structural modification.

The endothelial cell that forms the lymphatic capillaries wall are not packed tightly and overlap each other very loosely which makes easy openings in the structure called mini valves.

When the pressure of fluid in interstitial space is high then the mini valves become open and allow the fluid to enter the lymphatic capillary. So mini valves are the unique structural modification that increases permeability in lymphatic capillaries.

A 21-year-old female was lost in the woods for several hours. The ambient temperature is 25 degrees Fahrenheit. She is lethargic
Annette [7]

The female should be gently wrapped with dry blankets due to exposure of temperature of about 25 degrees Fahrenheit.

Explanation:

Prolonged exposure to extreme heat or cold conditions can impair the body’s temperature control system.  

In the above case the patient is exposed to extreme cold condition in a wood with a freezing temperature of 25 degrees Fahrenheit (-3 degrees Celsius) which leads to hypothermia and frostbite.

Extreme cold conditions can freeze the tissue layers of the parts of the skin exposed like those of the face, hands and feet especially. Due to this the skin becomes white (even grayish yellow or blue) and waxy, cold and numb, and the outer surface may become hard and blistered. There will also be extreme pain, stinging and tingling sensation in the exposed areas.  

These changes are mainly due to impaired blood circulation and hypothermia. Hypothermia which is lowering of body temperature causes confusion and lethargy.

The first-aid given for frostbite primarily includes warming the body. The affected person’s body should be covered with warm and dry blankets gently and loosely and any wet clothes should be removed.  

So when the body is warmed, the body temperature also will increase and correct the hypothermic symptoms like lethargy and confusion.
