Answer:
5732 years
Explanation:
Radioactive decay can be determined by using the equation:
where;
= number of decayed atoms at time (t)
= initial number of decayed atoms
= decay constant
So, if we equate the natural log of the above; we have:
where;
= 
= 
= 
t = 5732.01 years
t = 5732 years.
Hence, the fossil is 5732 years old.
Answer:
An enzyme whose activity is controlled by allosteric regulation.
Explanation:
Enzymes are proteins that<em> accelerate</em> chemical reactions within the cell. Enzymes bind to the substrate in the active site, catalyzes the reaction, for example the breakdown of the binding molecule, and release the product or products.
The enzyme activity need to be regulated. One of the mechanisms by which this occurs involves effector molecules, usually small molecules which bind to the regulatory site, called allosteric site. The binding to effector molecules may activate or inhibit the enzyme activity, consequently increasing or decreasing the rate of the reaction.
This mechanism of enzyme control is called allosteric regulation.
The description of the protein isolated fits with this features, an enzyme whose activity is controlled by allosteric regulation.
Answer:
Avery expanded on Griffith's observations by demonstrating that it is the DNA, and not the proteins, that is responsible for the genetic information.
