You know that mRNA does not have thymine(T) in it. Instead it has uracil(U). So adenine(A) pairs with uracil(U) and cytosine(C) pairs with guanine(G). I hope that helps!

1.solve for p
Mnenie [13.5K]
<h3>1. <u>Answer;</u></h3>

<em>p =-3/2p</em>

<h3><u>Solution;</u></h3>

To solve for P  in the equation;

= 3(p + q ) = p

We open the brackets;

= 3p + 3q = p

Then, we combine the like terms together, we get;

 <em>  3p - p = -3q</em>

<em> Therefore; 2p = -3q</em>

<em>   hence;  p = -3/2q. </em>


<h3>2. <u>Answers</u>;</h3>

<em>b = 19/2</em>

<h3><u>Solution;</u></h3>

To solve for b when the value of a = 3

4a = 2b - 7

we substitute 3 with a in the equation

<em>( 4 × 3 ) = 2b -7</em>

<em>12 = 2b -7</em>

<em>Then, make b the subject</em>

<em>19 = 2b</em>

<em>b = 19/2</em>


<h3>3. <u>Answer;</u></h3>

<em>r =d/t</em>

<h3><u><em>Solution;</em></u></h3>

To solve for r 

d= rt.

In order to get r, we divide both sides by t

<em>d/t = rt/t</em>

<em>r =  d/t</em>


<h3>4. <u>Answer;</u></h3>

<em>Width = 30 units</em>

<h3><u>Solution;</u></h3>

The width of a rectangle with a given perimeter of 90 and length is 15.

The perimeter of a rectangle is given by;

Perimeter= 2(Length + Width)

Thus;<em> Perimeter = 90 , length=15 </em>

<em> 90 = 2 (W + 15)</em>

<em>Dividing both sides by 2,</em>

<em>45 = w + 15 </em>

<em>Subtracting from both sides;</em>

<em>W = 45 -15 </em>

<em>W = 30 </em>

Therefore,<em><u> the width of the rectangle is 30 units</u></em>

How is the types of venation in a plant related to the types of root it has and the number of cotyledons in its seeds?​

Answer:

dicotyledonous

Explanation:

The veinlets form a network in the leaf lamina that is why the type of venation reticulate meaning network. So all dicots have dicotyledonous seeds, a tap root system and leaves with reticulate venation. ( with some exceptions of dicots having parallel venation in leaves like Calophyllum)

A researcher while working in vitro (outside cell) added helicase enzyme which resulted in the untwisting of the DNA helix. But
Nadusha1986 [10]
The answer is <span>Topoisomerase.

Topoisomerase is an enzyme responsible for twisting of DNA helix. After DNA strand is untwisted by helicase enzyme, DNA must be twisted again so the normal function of DNA can be sustained. If left untwisted, the replication fork will continue to grow, the normal function of DNA will stop.</span>
