Answer:Species Dynamics. This theory is quite straightforward: species that can colonize new areas faster and reproduce in greater number than they become extinct have the greatest chances to thrive. The tropics offer favorable conditions for these conditions to be met.
There Is More Diversity Near the Equator. ... Another argues that more solar energy is received around the equator, allowing for greater species richness. A third points out that equatorial tropics are the largest biome, so it makes sense that there would be more species.

e. None of these
Explanation:
The immune deficiency viruses (HIV) are retroviruses that use a reverse transcriptase (RT) enzyme to produce a single-stranded DNA (ssDNA) from an RNA template. The reverse transcription allows retroviruses to replicate their genetic material, which is integrated into the host's genome as a double-stranded linear DNA molecule in a similar way to the mechanism of insertion used by endogenous retrotransposons. The synthesis of DNA is started by cellular tRNAs (tRNA3Lys) that are packaged into the virion. After reverse transcription, the HIV DNA enters the nucleus of CD4 immune cells (also known as CD4+ T cells), and then it integrates into the genome to coopt the host's cell machinery for its own replication.
Answer:
As earth’s temperatures increase with climate change, the polar ice caps melt and the sea levels rise, leaving islands like Australia at risk of flooding and partial, permanent underwater submersion.
