Because they interfere witht he natural cycling of elements.
An example is crop harvesting. The practice of removing part or all of the crops grown from the soil accelerates the loss of nutrients from the soil. The cycling of nutrients from plant uptake and release is interrupted by crop removal.
Hope this helps!
Answer:
Here you go!
Explanation:
Grasslands are areas where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth.
Temp -20°C to 30° C (-4°F- 86)
Precip 500-900 mm a year
Humidity 50-60%
Mountain precip- more than 20 in
Mountains aren't very humid because they're elevated.
Answer:
These example represent the category of the carbohydrates.
Explanation:
Carbohydrates can be defined as poly hydroxy aldehyde or polyhydroxy ketone.There are many types of carbohydrates based on the number of sugar residue that they contain such as
1 Mono saccharide they are simple sugars which consist of one sugar residue such as glucose,fructose, galactose, xylose, arabinose, mannose
2 Di saccharides they consist of 2 monosaccharide residues linked together by glycosidic linkage such as sucrose consist of glucose and fructose linked together by β-2,1-glycosidic linkage.Maltose consist of 2 glucose sub units linked together by α-1,4-glycosidic linkage.
3 Poly saccharide they are complex sugar consist of more than 10 mono saccharide subunits linked with each other by glycocydic linkage.For example strarch the storage polysaccharide in plant consist several glucose sub units linked together α-1,4-glycosidic linkage.Cellulose consist of glucose sub units linked with eachother by β-1,4-glycosidic linkage.
Answer:
dopamine
Explanation:
The main cause of Parkinson's disease is the death of brain cells, especially in the area known as substantia nigra, responsible for the production of dopamine, a neurotransmitter that, among other functions, controls movement. This is a chronic, progressive neurological disease with no known cause that affects the central nervous system and impairs movement. The older the age, the higher the incidence of Parkinson's disease. According to statistics, in the vast majority of patients, it appears from 55, 60 years and its prevalence increases from 70, 75 years.
