One general effect of overuse of an environmental resource is the destruction of the ecosystem. Overuse of natural resources usually throw the ecosystem out of balance and disrupts the life of the living organisms which are living in that particular location.<span />
Water vapor , you need a liquid to have acid rain-(rain is water btw)
True. If the diameter of the afferent arterioles leading to the glomerulus increases due to vasodilation, which ultimately increases the net filtration pressure.
The filtration of blood occurs in the kidney, an excretory organ. The kidney is composed of numerous small units called nephrons, which is responsible for the blood filtration.
Glomerulus is part of nephron and the glomerular filtration occurs in the renal corpuscle of the kidney. This process is driven by hydrostatic and colloid osmotic pressure.
These pressures are collectively called net filtration pressure, which is influenced by the diameter of afferent arterioles.
If the arterioles constricts, net filtration pressure will decrease and if arterioles dilates, net filtration pressure will increase. This mechanism is regulated by neural, renal and hormonal regulation.

Vinegar is an extremely acidic liquid. Very few microorganisms (ie bacteria and fungus which cause foods to spoil) can survive in such an acidic environment. Among other effects, it can destroy their cell walls, and prevent their own enzymes working (enzymes are extremely pH sensitive). There are a small number of microorgamisms which are adapted to survive in extreme acidity. However, this adaptation prevents them from surviving in more 'normal' environments. Therefore, anything which can survive in the vinegar, will not likely survive on your kitchen surface, and the same is true the other way around. Therefore, as vitually nothing can colonise whatever is in the vinegar, the food will be very effectively preserved. . . . . . . . . . . you can say........................ . . the low pH a nd high acidity of vinegar destroy bacteria
Similar to the other types of muscle, smooth muscle contraction is caused by the sliding of myosin and actin filaments over each other. Calcium initiates contractions in a different way in a smooth muscle than in a skeletal muscle.
Smooth muscles use less energy to generate the given amount of force, can substain contractile force without fatigue & uses calcium from the sarcoplasic reticulum & extracellular space.
