CHICAGO (Reuters) - Lab experiments on a new strain of the H7N9 bird flu circulating in China suggest the virus can transmit easily among animals and can cause lethal disease, raising alarm that the virus has the potential to trigger a global human pandemic, researchers reported on Thursday.
Answer:
they feed off of the efforts to control the fires on forests
Explanation:
they cause heat trapping for wildfires to grow. These patterns occurred in 1880 as a result, led multiple forest fires that were hard to control and over time increased chances of happening again.
Answer:
The current taxonomic system now has eight levels in its hierarchy, from lowest to highest, they are: species, genus, family, order, class, phylum, kingdom, domain.
Explanation:
The correct answer is: B) continuous transcription of the structural gene controlled by that regulator
A regulatory gene is gene that encodes for a protein, such as a repressor (or activators) that controls the transcription of another gene or group of genes.
The regulatory gene of a repressible operon encodes for the repressor that inhibits gene transcription. So, when that repressor isn’t active, transcription occurs continuously.
