Does DNA control RNA?

Biology
2 answers:
svetoff [14.1K]3 years ago

Answer:

RNA is usually synthesized from DNA.

ElenaW [278]3 years ago
3 0

Answer:

RNA is usually synthesized from DNA. The synthesis usually requires one or more enzymes like RNA polymerase. The DNA strand is used as a template or guide on which the RNA is formed

In reality, there is much more to the RNA story. The central dogma of molecular biology suggests that DNA maintains the information to encode all of our proteins, and that three different types of RNA rather passively convert this code into polypeptides.

why must the symbol +- be written in front of the radical to write the inverse of the function f(x)=x^2?
oee [108]
Here is why:

When we solve for the inverse function (see the particular step below;  when we have:  " y² = x " ;

We take the "square root" of EACH SIDE of the equation; to isolate "y" as a single variable on one side of the equation;

→  √(y²) = √x ;

→ |y| = |√x| ;

y =   ± √x ; 

Because when we take the square root — or any "even root", for that matter—we have two solutions: of a variable, we have TWO SOLUTIONS:  a positive value; and a negative values;  
 
→  since:  1)  a "negative value"; multiplied by a "negative value" ;                       equals a "positive value" ;  
                 →  and as such:  a "negative value" ;
multiplied by that same "negative value" ;
           {that is:  a "negative value", "squared (i.e "raised to the power of "2"} ; ,
                 →  results in a positive value ; 
→ and since:  
                2)  a "postive value";  multiplied by a positive value" ;                       equals a "positive value" ;  
                 →  and as such:  a "positive value" ;
multiplied by that same "positive value" ; 
           {that is:  a "positive value", "squared (i.e "raised to the power of "2"} ; , 
                 →  results in a "positive value";
→ and since:
                3)  any given integer, in it "positive value", squared (i.e. raised to the power of "2");  results in a "positive value" ; 
→and since:  
               4)  that same aforementioned integer; in its "negative value" form, squared (i.e. raised to the power of "2"); results in that same aforementioned "positive value". 
________________________________________________________
Note the following:
________________________________________________________

"Given the function:  "f(x) = x² " ;   Find the "inverse function" .

Let "y" = f(x) " ; 

and write as:  " f(x) = y = x² " ;  

→  " y = x² " ; 

→ Now, rewrite the equation;  replacing the "y" with "x" ;
 and replacing the "x" with "y" ; 

→  " x = y² " ;  

Now, rewrite the question; isolating "y" as a single variable;  
   with no coefficient (save for the "implied coefficient of "1" ) ; 

→  " x = y² " ;  

↔  " y² = x ; 

Now, take  the square root of EACH SIDE of the equation; 
    to isolate "y" on one side of the equation; 

→ √(y²)  = √x ; 

→ |y| = |√x| ; 

→ y =  ± <span>√x .
</span>
Replace the "y" with " f ⁻¹(x)" ; to indicate that this the "inverse function" ; 

and write the "inverse function" :

→ " f ⁻¹(x) =  ± √x " ;

Which parts of a nervous reflex arc is usually a muscle or gland?
Alla [95]

The given question is incomplete as it does not have the options which are:

a) Sensory receptor

b) Sensory neuron

c) Motor neuron

d) Effector

e) Integration center

Answer:

The correct answer is option-Effector

Explanation:

A reflex arc is the mechanism of the neurons which controls the reflex action or involuntary responses or the instantaneous responses of the organisms.

The reflex arc involves the sensory receptors, sensory neurons (transmit signals from sense organ to spinal cord), motor neurons (transmit signals from spinal cord to muscle), Integration centre in the spinal cord and effector.

An effector represents the gland or the muscle which receives the transmitted signal from the motor neuron and responds by showing movements.

Thus, option-Effector is the correct answer.
