Answer:
C
Explanation:
I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.
ALOT of words please lmk if it makes sense
A theory in science is a remark on what happened
In an experiment the HYPOTHESIS is tested. The hypothesis is the assumption, that you make about something. Example would be, you believe (hypothesize) that the baking soda will react faster in vinegar than in water. You then test it out (or preform and experiment) to see if your hypothesis is correct or wrong.
Answer:
D. The system provided an organized way to classify living things and it has been able to grow and develop. There is a place to enter new organisms as they are discovered or new evidence occurs
Explanation:
Carolus Linnaeus is a Swedish Botanist is universally referred to as the FATHER OF TAXONOMY because of his contribution to the development of a system of naming and classifying species, which is still globally recognized today. Linnaeus proposed the binomial nomenclature system which uses two of the hierarchical classification to name organisms i.e. genus and species. For example, humans are Homo sapiens; Homo (generic name), Sapien (specific name).
Modern scientists later modified Linnaeus classification by adding new ranks in order to accommodate new species and removing incorrectly classified organisms but Linnaeus classification remains the foundation. One important modification was the inclusion of a new taxon called DOMAIN.
