Answer:
Explanation:
A scientific researcher performs scientific methods to answer any natural process. The researcher will follow the protocol of a scientific method which includes: observe the natural phenomenon, ask related questions, suggest a hypothesis, perform the experiment and suggest answers.
In the given question if the researcher has to study about the flu virus, the possible questions he would ask will be:
1. The life cycle of the flu virus.
2. Effect of the virus on the life of an organism.
3. The mechanism used by the virus to replicate and to infect any organism.
4. Molecular mechanism of a virus.
The Silurian period occurred before the Neogene period.
I hope this helps.
Answer:
Jacob and Monod were intellectually primed to draw the conclusions they did concerning regulation of the lac operon. In part, this was due to their fascination with mechanisms of enzyme regulation. They knew that the activity of some enzymes is regulated when their reaction product binds to the enzyme, changing its shape and therefore its activity. This knowledge allowed them to easily make the intellectual leap to propose B) allosteric regulation of the repressor
Explanation:
When we talk about the mechanisms of enzyme regulation, we refer to allosteric regulation of the repressor. The Allosteric control of transcriptional regulatory proteins allows organisms to react to changes in environmental and metabolic conditions. Also, it is s a thermodynamic phenomenon. When it binds one molecule, the affinity with which a protein binds to a second molecule is altered.
Answer: ATP releases energy when it converts to ADP .
Explanation:
During energy needs, the body cells directs the loss of a phosphate group (Pi) from ATP (Adenosine triphosphate) to yeild ADP (adenosine Diphosphate), and a further loss will yield AMP (adenosine monophosphate). For each loss energy is also released when a phosphate is removed
The reaction involves the addition of water, so it is a hydrolytic reaction, and is catalyzed by enzymes of the mitochondria, and is represented as the equation below:
ATP + H2O → ADP + Pi + free energy
