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!

Whats the difference between covalent and ionic bonds
AlekseyPX

Answer:

An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. ... Ionic bonds form between a metal and a nonmetal. Covalent bonds form between two nonmetals.

irakobra [83]

Answer:

V₂= 33581.4  ft³

Explanation:

Given data:

Initial temperature = -15 °C (-15+273 = 258 k)

Initial volume = 28500 ft³

Final temperature = 31 °C (31+273 = 304)

Final volume = ?

Solution:

According to the Charles's law

Temperature and volume are directly related to each other.

V₁/T₁ = V₂/T₂

V₂ = V₁×T₂ /T₁

V₂ = 28500 ft³ × 304 k / 258 k

V₂ = 8664000 ft³.k/ 258 k

V₂= 33581.4  ft³
