Answer and explanation;
According to twin studies attitudes may be genetically based, research has supported that Identical twins are more likely to share similar attitudes. Attitudes change as the result of behavior and not the other way around
Genetic factors may influence general dispositions and condition-ability that may influence formation of more specific attitudes. Controlled twin studies in US and Sweden reveal that identical twins share more similar attitudes than fraternal twins.
Answer:
Because there are other elements that get in touch with it. And over time with, evolution, erosion and temperature their particles tend to mix. So what once was very common became mixed over time.
Answer:
Fever or elevated body temperature might be caused by:
A virus.
A bacterial infection.
Heat exhaustion.
Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)
A malignant tumor.
Many illness-causing microbes do best at the body's normal temperature. A fever raises the temperature beyond which certain microbes need to reproduce. A fever also kicks your child's immune system into high gear, spurring the rapid production of bug-clobbering white blood cells.

Answer:
0.398
Explanation:
According to friction, the frictional force is directly proportional to the normal reaction
Ff = nR
Ff is the frictional force
n is the coefficient of friction
R is the reaction
Reaction is equal to the weight
R= W = 9.3N
Fm = Ff = 3.7N
Fm is the moving force
Get the coefficient of friction
n = Ff/R
n = 3.7/9.3
n = 0.398
Hence the coefficient of friction for the surface is 0.398
Use the equation
The final velocity 
is 68 m/s, the acceleration 
is 8 m/s^2, and the net displacement 
is 33 m, so you can solve for the initial velocity 
:
