Answer:
False
Explanation:
Almost all coal that is used today has its origins in the Carboniferous period. The Carboniferous period was a warm and wet one, with the majority of the land being swampy and covered with dense rainforests of ancient tree species. By the end of this period, the climate quickly changed, resulting int he collapse of the rainforests. As the trees were dying out, they were falling in the swamps, quickly being covered by the mud, so remaining largely preserved. Over time they got exposed to higher pressure and temperatures as they were getting deeper into the crust, eventually resulting in the formation of the coal.
Answer:
a) Kingdom, phylum, class, order, family, genus, species.
Explanation:
Kingdom is the broadest taxonomic category after domain as proposed by Linnaeus. The Linnaean hierarchy of taxon identifies species as the most specific taxon that include only those organisms that can interbreed to produce the fertile progeny.
Several species with some common features are placed in same genus while related genera are placed in same family. Likewise, related families are placed in same order and the related orders are placed in same phylum.
Hence, kingdom is the least specific or broadest taxon that includes all the related phyla while species is the most specific taxon that include only the organisms that can interbreed.
Here are the four postulates of natural selection, according to Charles Darwin:
1. variability - refers to different mutations that create different species
2. heritability - refers to the genes that are passed from one organism onto its descendants
3. overproduction of offspring - refers to the fact that more "children" is born than dies
4. natural selection - refers to those organisms that survive because they adapt to their surroundings better than those who will die
A universal genetic code allows "the processes of transcription and translation to produce the same proteins in all species."
To say that the genetic code is universal it means that it is read/interpreted in the same exact way in all cells. This is that the same group of three nucleotides, a codon, will always translate into the same amino acid in any cell leading to the formation of the same protein, or at least a protein with same amino acids when first formed.
