Answer:<span>Archaea; Bacteria
</span>
A recent tree of life refers to two
domains of life (bacteria, archaea) and places the Eukarya inside the Archaea domain, implying that Archaea and Eukarya had a common ancestor. This hypothesis says that eukaryotes arose directly from an Archaea, and acquired the cell structure of an Eukarya organism.
The most likely answer to your question would be (3) gene expression being affected by the environment.
This is the correct answer because these two species had each different environmental influences where one had enough light, the other didn't. Because this difference was apparent, the genetic potential that both of the species shared eventually manifested into something different. Intensely colored wings for some butterflies and paler wing colors for other butterflies.
Neurogenesis
As recently as two decades ago, scientists believed we were born with all the neurons we would ever have. But the discovery of neurogenesis occurring in certain brain areas in monkeys gave rise to the hope that someday scientists will be able to induce the adult human brain to heal itself.
Neurogenesis is the process by which new neurons are created and developed in the brain. The new neurons are created by neural stem cells and it happens in almost all species of animals. Neurogenesis is effectual during embryonic development and completely through adult life in different organisms.

D) The
blue parrot population has likely increased in the last 200 years.
The answer is B. This is because the graph shows the highest number of green parrots in the 'deep forest' category of environment, whereas the numbers in the 'grassland' and 'scrub forest' are less. Since the forested area in Brazil has decreased rapidly, this means that the preferred environment of the green parrot has decreased, probably resulting in a decline in the green parrot population

Answer:
Research
Explanation:
Research is a deliberate attempt to find answer or solution to a problem along with help of observation, study, survey, comparison, literature review and experimentation.
It is in other way a search for knowledge through systematic way of finding solutions to a problem.
The research methodology comprises of following stages –
Stage I – Observing a problem
Stage II – Formulating a hypothesis
Stage III – Collecting the data
Stage IV – Analysis of facts and data
Stage V – Finding a solution or reaching a conclusion
