Answer: Nitrogenous bases guanine(G), adenine(A), cytosine(C) and thymine(T) forms the rungs of the ladder in twisted ladder structure of DNA.

Explanation:

Rungs of the ladder are normally horizontal small logs placed one after the other with small gaps between them on the two vertically standing logs of the ladder.

Since, DNA resembles the twisted ladder structure the rungs of the ladder structure of DNA are the organic nitrogenous basic molecules which are associated to their respective base with the help of hydrogen bonding.

In DNA, there are four bases guanine(G), adenine(A), cytosine(C) and thymine(T). These bases through hydrogen bonding are associated with there respective bases :adenine is bonded to thymine and guanine is bonded cytosine.

(A=T): Two hydrogen bonds between the bases

(C≡G): Three hydrogen bonds between the bases.

C=h/[M(T2-T1)] solve for T1

vodka [1.7K]

Explanation:

This is expressing as a subject of a formula of a specie.

This equation is used in solving for specific heat capacity of a material;

equation:

c = $\frac{h}{M(T2 - T1)}$

First cross multiply:

c[M(T2 - T1)] = h

Then multiply both sides by $\frac{1}{c }$ :

$\frac{1}{c }$ x c[M(T2 - T1)] = $\frac{1}{c }$ x h

M(T2 - T1) = $\frac{h}{c}$

Multiply both sides by $\frac{1}{M}$

$\frac{1}{M}$ x M(T2 - T1) = $\frac{1}{M} x \frac{h}{c}$

T2 - T1 = $\frac{h}{Mc}$

Now rearrange to produce;

T1 = T2 + $\frac{h}{Mc}$

Properties of substances can be classified as physical or chemical properties. Which statements describe chemical properties? (C

Tamiku [17]

The correct answers are options C, that is, silver tarnishes and becomes black when exposed to oxygen, and option E, that is, diesel fuel burns when it is heated.

Chemical changes refer to the modifications in which the chemistry at molecular level is modified as the initial substance gets transformed into a new and different final substance. This change occurs with the dissociation of old bond and production of new bonds respectively.

Silver gets tarnished and becomes black when exposed to oxygen. This refers to a chemical change as silver a white and lustrous substance gets transformed into a tarnish black final substance. However, silver does not easily react with oxygen at usual circumstances. It easily reacts with sulfur comprising components in the air and generates black compound as Ag₂S.

Burning of diesel fuel when it is heated. Diesel refers to a mixture of hydrocarbons varying approximately from C₁₀H₂₀ to C₁₅H₂₈. When these hydrocarbons get burnt they generate novel substances, that is, carbon dioxide and water. Hence, it is also a chemical reaction.
