For centuries scientists thought the Universe always existed in a largely unchanged form, run like clockwork thanks to the laws of physics. But a Belgian priest and scientist called George Lemaitre put forward another idea. In 1927, he proposed that the Universe began as a large, pregnant and primeval atom, exploding and sending out the smaller atoms that we see today.
His idea went largely unnoticed. But in 1929 astronomer Edwin Hubble discovered that the Universe isn’t static but is in fact expanding. If so, some scientists reasoned that if you rewound the Universe's life then at some point it should have existed as a tiny, dense point. Critics dismissed this: the celebrated astronomer Fred Hoyle sarcastically called this concept the “Big Bang Theory"
Answer: C. The mutation resulted in a beneficial trait that enhanced survival.
Explanation:
The bacteria was able to "evolve" and adapt to the Nylon being in its environment.
For an atom to become a positively charged ion it must lose negatively charged electrons.
According to Charles Darwin's Theory of Origin of Species, an organism either develops or losses an attribute according to its adaptation to survive in a competitive environment. This is same with humans or salamanders. The loss or the retention of limbs may indicate the survival purposes of the species.
<span>The centromeres split. The two chromatids separate, and each chromatid becomes a new chromosome. The new chromosomes move to opposite ends of the cell. The cell stretches out as the opposite ends are pushed apart.
Hope this helps! :)</span>
