Which statement best describes the general relationship between stream velocity and the size of the sediment particles transported by the stream?

1.

as the stream velocity decreases, the diameter of the sediments transported increases.
2.

as the stream velocity decreases, the diameter of the sediments transported remains the same.
3.

as the stream velocity increases, the diameter of the sediments being transported decreases
4.

as the stream velocity increases, the diameter of the sediments being transported increases.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
