The correct answer is the option (d) the increase of carbon dioxide.

The increase of carbon dioxide in the earth's early atmospheric conditions made the aquatic dwelling organisms to adapt into terrestrial dwellers. Volcanic eruptions released a few gases, of which, carbon dioxide was abundantly released. It is a vital requirement for all living organisms. The first terrestrial plants appeared which used the carbon dioxide for the synthesis of food by the process of photosynthesis. Thus, this continuous availability of carbon dioxide helped the land dwelling plants to evolve. This increased the oxygen content in the atmosphere which made the animals to evade the terrestrial habitat.

The build up of ozone was not an earth's early atmospheric condition and the stromatolites were the sedmientary rock layers of water bodies like oceans. The formation of rust on the earth's crust did not help the land dwelling animals to evolve.

Thus, the increase in the carbon dioxide helped the land dwelling oragnisms to evolve.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
            x + y + z = 140 meters


According to the proportion theorem,

\frac{x}{40} = \frac{y}{30}

Solving for x, using cross multiplication:

\frac{x}{1} = \frac{40y}{30}

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

 4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

Protein synthesis can be compared to building a doghouse. Sondra wanted to build a doghouse and found a book in the reference se
Nimfa-mama [501]

The correct answer is mRNA.

mRNA or messenger RNA is synthesized during the process of transcription, from DNA molecule which is used as a template. mRNA contains information about protein synthesis (translation) in the form of nucleotide triplets or codons.

In the example above: reference book is DNA molecule (template for copies), copies are mRNA, wood is amino acids (building blocks) and doghouse is protein.

The Go' for the reaction Citrate  Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate  α-Ketoglutarate is -267
xz_007 [3.2K]

Answer:

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Explanation:

ΔG°' for Citrate is +6.64 kJmol-1

ΔG°' for Isocitrate is -267 kJmol-1

ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant

ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1
