Water is the main constituent on the earth surface. It is important for all living beings to survive. It is a transparent, odourless, colourless chemical substance. Water has vital role in atmosphere. It undergoes several cycles. In water cycle, water from rivers, lakes and streams enters the atmosphere through Evaporation. In evaporation the element or the compound in it's liquid state changes to gaseous state below the temperature at which the it boils. This is due to the high temperature. Due to high temperature the water from different water bodies enters the atmosphere in the form of vapours. In the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. Transpiration is a process by which the moisture is transferred from roots to the outside of the leaf whic
Therefore, In water cycle, water from rivers, lakes and streams enters the atmosphere through vaporisation. in the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. In nitrogen cycle, the water as well as dead organism moves nitrogen from the atmosphere into the soil.
Answer:
The autonomic nervous system is the main neural regulator of circulation and blood pressure in the short term and beat by beat and exerts its function through various reflexes that regulate vasomotor tone, heart rate and cardiac output. At the renal level, the renin–angiotensin–aldosterone system is possibly the most important in the maintenance of arterial homeostasis.
Explanation:
Blood pressure is regulated by a series of interrelated autonomic systems and humoral reflexes, which continually adjust the determining elements of the system (heart rate, stroke volume, total peripheral resistance and circulating volume).The effective circulating volume is controlled by a series of reflex systems, which obtain information about the perfusion pressure (baroreceptors in the carotid bulb and aortic arch), plasma osmolarity (hypothalamus) and urinary sodium (distal tubule).The kidney has its own self-regulatory mechanisms. The reduction in renal blood flow is detected at the level of the mesangial cells of the juxtaglomerular apparatus, starting the renin-angiotensin system. The increase in angiotensin II produces on the one hand local vasoconstriction, and on the other hand stimulates the production of aldosterone by the adrenal cortex with the consequent tubular reabsorption of sodium and water.Antidiuretic hormone or vasopressin (released from the hypothalamus by stimulation of arterial baroreceptors and also by stimulation of angiotensin II) also acts at the renal level, which acts as a powerful and water-saving vasoconstrictor in the distal tubule.
Answer:
The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
Explanation:
A structure formed from molecules that combine to make up cells is called an atom.
Explanation:
.For the our health because if the environment is saved the we are able to get the fresh air.
.For decreasing global warming because if environment is saved then the pollution is controlled.
.For decreasing deforestation which can control landscape because saving the environment can also be taken as saving trees.
For saving the animals because the habitat of animal is forest which need to be protected by protecting environment.
.For saving the natural resource which are also the reasons of income because it attracts tourists.
