Answer:
C. Some marsupial mole rats had a natural immunity to the virus.
Explanation:
According to Darwin's evolutionary theory, over time some of marsupial moles may have acquired natural immunity which evolves as an adaptive trait in the population. Since these organisms have more chance to survive and reproduce (survival of the fittest), they will likely transmit the natural immunity to the next generation

D
Explanation:
Things like unhealthy eating or drinking habits, and exposure to asbestos can harm your health, but it can't cause genetic disorders and diseases. Only DNA mutations can cause them.
Mutations in the DNA sequence can occur during meiosis, or the creation of gametes. The gametes can become defective. For example, extra or excess chromosomes can be produced. If defective gametes fertilize, the offspring can end up with genetic disorders.
Answer:
En resumen, estructuras análogas son aquellas que poseen una función semejante partiendo del mismo medio, pero cuyo origen es diferente. Si dos estructuras tienen la misma función por medios semejantes y además parten del mismo origen, son estructuras homólogas.
Explanation:
The given statistics indicate the comparison of the genome of the various organisms. Genome can be defined as the complete set of the genetic material (chromosomes/genes) present in the cell of an organism, or, the haploid set of the chromosomes which are present in an organism's gamete cell. Since, the given statistics are comparing the percentage of the genetic material which is similar among different organisms, the blank can be filled with 'genome'.
I dont do biology so im not sure but i think it means they are currently fighting off an infection so they have produced more white blood cells as part of their immune system kicking in... thank house if its right!
