The answer is Energy
Explanation: in sound waves , energy is transferred through vibration of air particles or particles of a solid through which the sound travels
Answer:
The stickiness in the inner walls allows them to be easily coated with the desired antigens, this translates in the use of a smaller amount of antigen. If the walls weren't sticky there's a possibility the antigen won't stick to them and therefore the result of the ELISA can be a false negative.

Answer:
The Egg
Explanation:
personally the Chicken who would lay the egg would have to come from an Egg itself, then It would have to grow up and then Produce an egg that will produce a chicken and so on.
Answer:
1) Yes, the work done by gravity during the trip upward is -41.405·m J
2) Yes, the work done by gravity on the ball during the trip downward = 41.405·m J
Explanation:
The given parameters are;
The initial velocity of the ball on the way up = 9.1 m/s
The final velocity of the ball on the way up = 0 m/s
The initial velocity of the ball on its trip downward = 0 m/s
The final velocity of the ball on its trip downward = 9.1 m/s
1) The work done by gravity on the trip upward = The change in kinetic energy of the ball
The change in kinetic energy of the ball = 1/2 × m × 9.1² = -41.405·m J, given that the initial kinetic energy is 41.405·m J and the final kinetic energy is J
Where;
m = The mass of the ball
Therefore, the work done by gravity during the trip upward = -41.405·m J
2) Similarly gravity does work on the ball during the trip downward = 41.405·m J.
