Answer:
The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split
The two events that occur when gravity causes a nebula to collapse into itself are:
A. Nuclear fusion start.
B. A new star forms.
Explanation:
- Nebula are giant clouds of dust and gases.
- These clouds are considered as progenitors of stars and planets.
- The gravitational pull within these giant clouds result these large masses to collapse towards their centre.
- The gravitational collapse results in tremendous rise in temperature till a point where nuclear fusion begin .
- The stars are born out of such mechanism and act as a source of heat and light in universe.
The answer is FALSE.

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.
