One of the bases of DNA is replaced by Uracil. B is the correct option.

<h3>Features of RNA</h3>
  • RNA has ribose sugars, unlike DNA which has deoxyribose sugars
  • It contains Uracil instead of Thymine in DNA
  • RNA is single-stranded, unlike DNA which is double-stranded
  • There are 3 forms, tRNA, mRNA, and rRNA.

Answer:

“Birth of a Nation”—D. W. Griffith’s disgustingly racist yet titanically original 1915 feature—back to the fore. The movie, set mainly in a South Carolina town before and after the Civil War, depicts slavery in a halcyon light, presents blacks as good for little but subservient labor, and shows them, during Reconstruction, to have been goaded by the Radical Republicans into asserting an abusive dominion over Southern whites. It depicts freedmen as interested, above all, in intermarriage, indulging in legally sanctioned excess and vengeful violence mainly to coerce white women into sexual relations. It shows Southern whites forming the Ku Klux Klan to defend themselves against such abominations and to spur the “Aryan” cause overall. The movie asserts that the white-sheet-clad death squad served justice summarily and that, by denying blacks the right to vote and keeping them generally apart and subordinate, it restored order and civilization to the South.

“Birth of a Nation,” which runs more than three hours, was sold as a sensation and became one; it was shown at gala screenings, with expensive tickets. It was also the subject of protest by civil-rights organizations and critiques by clergymen and editorialists, and for good reason: “Birth of a Nation” proved horrifically effective at sparking violence against blacks in many cities. Given these circumstances, it’s hard to understand why Griffith’s film merits anything but a place in the dustbin of history, as an abomination worthy solely of autopsy in the study of social and aesthetic pathology.

Find δs o for the combustion of methane to carbon dioxide and liquid water.
mote1985 [20]

The entropy change ΔS for the combustion of methane to carbon dioxide and liquid water is -242.6 J/mol.K

<h3>What is the Entropy in a Chemical system?</h3>

In a chemical system, Entropy (ΔS) is a quantitative measure of the variety of possible ways to disperse energy inside a chemical system.

  • In an isothermal process, entropy is determined as the quantity of heat transmitted to a system.

The chemical reaction for the combustion of methane can be expressed as:

\mathbf{CH_{4(g)} + 2O_{2(g)} \to CO_{2(g)} + 2H_2O_{(l)}}

The standard entropy of the combustion is expressed as:

\mathbf{\Delta S^0 =(S^0 _{CO_{2}} + 2 \times S^0 _{H_{2}O} )+(-S^0 _{CH_{4}}  -2 \times S^0 _{O_{2}} })

Replacing the standard entropies of the compounds into the above equation, we have:

\mathbf{\Delta S^0 =(213.8 \8 \ J/mol.K + 2 \times69.92 \ J/mol.K  )+(-186.16 \ J/mol.K -2 \times 205.04 \ J/mol.K})

\mathbf{\Delta S^0 =-242.6 \ J/mol.K}

When matter and energy change forms within a closed system?
3241004551 [841]
Matter becomes energy. Law of thermodynamics states that matter can't be created or destroyed, but can transfer to another form. If it was closed in with the form of energy, it would be transferred to the form of energy.
