Answer:

The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.

What effect does the Earth spinning on its axis have on winds and currents?
olasank [31]

Answer:

B) Global winds will move along a curved path and therefore cause ocean currents to curve.

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.

This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.

Basically, the effect of the Earth spinning on its axis have on winds and currents is that Global winds will move along a curved path and therefore cause ocean currents to curve. As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises. Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.

Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.

Thus, for the trp operon , the addition of tryptophan (the effector molecule) to the E. coli environment shuts off the system because the repressors binds at the operator.
