<span><span><span>Understanding the nature and appearance of our galaxy is no small feat, for we live within a disk of obscuring gas and dust.Astronomers do not think that a supermassive black hole at the center of a galaxy is unique to the Milky Way. Rather, it appears to be quite typical of the almost innumerable galaxies in the observable universe. The fact that black holes may be the rule rather than the exception makes it even more important that we continue to study them.</span> </span><span> <span> </span></span></span>
Answer:
Genetic variation
Explanation:
It could lead to natural selection, but natural selection isn't the cause. Many years down the road you could see a particular variation having a higher population, which is the result of natural selection/survival of the fittest via better camouflaging from predators.

The egg example that Czerski uses to explain the law of conservation of angular momentum is that according to the principle of conservation of angular momentum, anything that is spinning will keep spinning until it is stopped.
Similarly, in the example of an egg given by Czerski If you spin a raw egg and then try to stop it by placing your finger on the shell, the egg will continue to spin since the uncooked portion of it is still in motion.
The law of conservation of angular momentum states that an object's angular momentum won't change in the absence of any external tension.
Its angular momentum is conserved as long as there is no net external torque acting on the system.
In forensic science, reconstruction of crime scenes is a crucial application of physics because instances involving accidents, body falls from heights, weapon projectile motion, bullet or tool case analysis, glass penetration of quick stone.
And law of conservation of angular momentum plays a great role in the reconstruction of those crime scenes and also in the firearm identification.
