Which explains why the graph is not a function? It is not a function because the points are not connected to each other. It is n

ot a function because the points are not related by a single equation. It is not a function because there are two different x-values for a single y-value. It is not a function because there are two different y-values for a single x-value.

As per the definition of a function,which requires that there be a single discrete output (y) for every value of input (x), the graph is not a function because there are two different y-values for a single x-value.
Examples of functions are:
y = x
y = x² - 5
And many other. However, what all of these have in common is the fact that whenever a value of x is input, it gives one value of y only.

The half-life of Carbon-14 is 5730 years. Suppose a fossil is found with 50% of Carbon-14 as compared to a living sample. How ol
nata0808 [166]

Answer:

5732 years

Explanation:

Radioactive decay can be determined by using the equation:

N_t = N_0e^{- \lambda t}

where;

N_t = number of decayed atoms at time (t)

N_0 = initial number of decayed atoms

\lambda = decay constant

So, if we equate the natural log of the above; we have:

In(N_t) = In(N_0)-\lambda t

\frac{In(N_t)} { In(N_0)}} = -\lambda t

where;

\lambda = \frac{0.693}{t_{1/2}}

\lambda = \frac{0.693}{5730}

\lambda = 1.209*10^{-4

In(\frac{50}{100}) =-(1.209 *10^{-4})*t

-0.693 = -(1.209*10^{-4})*t

t= \frac{0.693}{1.209*10^{-4}}

t = 5732.01 years

t = 5732 years.

Hence, the fossil is 5732 years old.

You have isolated a previously unstudied protein, identified its complete structure in detail, and determined that it catalyzes
Finger [1]

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.
