The intervertebral discs, which are between vertebrae, are the parts that prevent the vertebrae from grinding against one another.
The intervertebrals discs act as a cushion; they absorb the stress and shockw that occur during movement, preventing such grinding.
The first famous natural scientist to determine how plants change with altitude on tall mountains was Alexander Von Humboldt and Aime Bonpland when climbing some very high volcanoes in South America like Chimborazo at well ove 20,000 feet high and they observed that different plants grow at different altitudes as altitude increases so that as the mountain was ascended the new environments of temperature, moisture,etc would become abiotic for the lower plants but acceptable for the higher elevation plants. In these cases in South America, the lower elevations had very warm temperatures and high humidity so would grow tropical plants with probably large leaves like palm trees etc. On the other hand at high elevations the temperature would be significantly decreased and probably humidity decreased too so only rugged plants like say lichens could grow. At intermediate elevations, most likely say pine trees could grow as I know they do at moderate elevations in Honduras for example.
Yes. They do it to escape the winter. Hope it helps.

The food in the protein group and dairy group are high in saturated fats and cholesterol, it raise LDL in blood.
<h3>
What is cholesterol?</h3>
Cholesterol is a waxy like substance synthesized from two sources such as liver and from animals like meat, poultry, diary product.
There are two types of cholesterol, one is bad called LDL cholesterol and second one is good called as HDL.
LDL narrow down the arteries by depositing fats in it, the condition known as atherosclerosis which leads to increase in risk for heart attack, stroke and peripheral artery disease.
On the other hand, HDL protect against heart attack and stroke
Third component called triglycerides are the common type of fat act as a reservoir of excess energy.
Hence, LDL is the correct answer.
