What can be inferred from this excerpt is : ( D ) Individuals with favorable variations survive and reproduce.
<h3>Effects of genetic variations in species</h3>
When the insecticide was sprayed some of the cockroaches survived and continued reproduction due to their resistance to the spray.Therefore it can inferred that although the cockroaches share the same genetic materials, the variations in individuals within the same specie played a role in the survival of some of the cockroaches.
Hence we can conclude Individuals with favorable variations survive and reproduce.

n descriptive investigations, we still haven't formed any hypothesis yet so we seek information by asking question.
It's net repeatable because repeating the questions over and over again without any clue about what we want to seek is completely waste of time
Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known. For instance, the trees could be extreme soil nutrient consumers—depleting soil nutrients at a faster rate than they can be replenished and rendering such soil infertile in a short period.
This suggests that the knowledge we know about these species is very limited. Through deeper research and gaining of samples of these bacteria, scientists will be able to determine how to culture these prokaryotes better, but this would still take a long period of time.
