In simpler terms, the Big Bang theory says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. In the first second after the universe began, the surrounding temperature was about 10 billion degrees Fahrenheit (5.5 billion Celsius). The cosmos contained a vast array of fundamental particles such as neutrons, electrons and protons. These decayed or combined as the universe got cooler. Over time, however, the free electrons met up with nuclei and created neutral atoms. This allowed light to shine through about 380,000 years after the Big Bang.
Answer: pathogen–host coevolution
Explanation:
A major driver of evolution is Reciprocal coevolution between host and pathogen. Rather than pathogen, one-sided adaptation to a nonchanging host, high virulence specifically favoured during pathogen–host coevolution. In all of the independent replicate populations under coevolution, the pathogen ( B. thuringiensis ) genotype BT-679 with known nematocidal toxin genes of C. elegans and high virulence specifically swept to fixation but only some of them go under one-sided adaptation,
so relative change in B. thuringiensis virulence was greater than the relative change in C. elegans resistance is due to the elevated copy numbers of the plasmid containing the nematocidal toxin genes
.
Carl Von Linneaus developed the system for classifying organisms.
Answer:
An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand "slips," or wrinkles, which allows the extra nucleotide to be incorporated.
