Rain wears it down, water seeps into cracks and turns to ice; creating bigger cracks, it can expand and contract due to temperatures rising and lowering and plants can grow on it so the roots break down the rocks to make room

4. If the DNA nitrogen bases were TACCGGAT, how would the other half of
Illusion [34]

Answer:

<u>ATGGCCTA</u>

Explanation:

For this we have to keep in mind that we have a <u>specific relationship between the nitrogen bases</u>:

-) <u>When we have a T (thymine) we will have a bond with A (adenine) and viceversa</u>.

-) <u>When we have C (Cytosine) we will have a bond with G (Guanine) and viceversa</u>.

Therefore if we have: TACCGGAT. We have to put the corresponding nitrogen base, so:

TACCGGAT

<u>ATGGCCTA</u>

<u></u>

I hope it helps!

The following reaction is part of the electron transport chain. Complete the reaction and identify which species is reduced. The
Olegator [25]

Answer:

FADH_2 + Q --> FAD + QH_2

The reactant that is reduced is FADH_2

Explanation:

The complete equation is as below:

FADH_2 + Q --> FAD + QH_2

<em>Recall that oxidation involves the gain of electrons while reduction involves the loss of electrons.</em>

In the above reaction, FADH_2 loses electrons to coenzyme Q and becomes reduced to FAD, hence the oxidizing agent. Coenzyme Q gains electrons and becomes oxidized to QH_2 , hence the reducing agent.

<u>In order words, </u>FADH_2<u> is reduced while coenzyme Q is oxidized.</u>

How many grams of fluorine are needed to react with 8.5g of phosphorus?
love history [14]

Step 1: write the equation:

                                          P₄(s) + 6F₂(g) → 4PF₃(g) 


Step 2: Molar mass of P₄ = 30.97 g/mol × 4 = 123.88 g/mol


Step 3: Number of moles of phosphorus

                                                    n = m/M 

                                                    n = 8.5 g/123.88g/mol

                                                    n = 0.07 moles


Step 4: 0.07 × 12 = 0.84 moles of fluorine.

Fluorine is diatomic gas so we multiplied the number of moles by 12.


Step 5: To find the mass of fluorine we multiply the number of moles with the molar mass.

                            Mass of fluorine = 0.84 ×  228 

                                                        = 191.52 grams.
