Answer:
A. 2 speciation events and 5 extinctions
B. 5 speciation events and 1 extinction
Explanation:
As we can see from the diagram, there were only 2 ,aim speciation events for lineage A. The extinction events were 5 for the A lineage. Hence, as the extinction event was more rapid than the speciation event so lineage A contains only one species.
On the other hand, the diagram shows that for lineage B there were 5 speciation events and just 1 extinction event. Hence, the number of species in lineage B were more at the time zero as just one extinction had occurred.
Answer:
phosphates will return to the soils or oceans again during decay
Hope I helped :D
Approximately 50% of human genome is composed of repetitive sequences. It contains approximately 3 billion of these base pairs that reside with 23 pairs of chromosome within the nucleus or our cells or called nucleotides. Genes in the genomes of invertebrates such as Drosophila is not like the human genes because the human genes contain more and larger introns than the genes in the genomes. The human genes are larger than the genes in the genomes. The genome sequence is ~99.9% similar in individuals of all nationalities. Complete set of deoxyribonucleic acid of a single cell of an organism or sequence for humans (Homo sapiens) is called Genome. It includes both protein-coding deoxyribonucleic acid genes and noncoding deoxyribonucleic acid.
