The answer would be a.
Biological catalysts are generally proteins (and a group of RNA molecules called ribozymes), but carbohydrates do not play such a role.
The answer is mass my friend
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.
Charles Darwin used domesticated animals to provide evidence for evolution by natural selection by showing "<span>Differences between breeds show that selection can cause species to change."</span>
Answer:
Process called magnetic separation
Explanation:
The magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using magnetic force.
This method is also used to separate the mixture of sand and iron fillings as iron is attracted by magnet.
