In which ways are RNA and DNA different?

2 answers:

6 0

Answer B: RNA has Uracil, DNA has Thymine

3 0

Answer:

d. all of the above is the correct answer.

Explanation:

These are the main difference between RNA and DNA

Sugar present in RNA is ribose sugar whereas sugar present in DNA is deoxyribose sugar.

Nitrogenous bases present in DNA are adenine, guanine, cytosine, and thymine whereas in the case of RNA nitrogenous bases present are adenine, guanine, cytosine and uracil which is replaced by thymine in DNA.

thus the all the above(D) options are correct.

Answer:

The correct answers are: Glucose, Sucrose.

Explanation:

The given question is an example of a Chemical Reaction.
A Chemical Reaction can be defined as the process by which two or more substances interact with each other in such a way that a rearrangement of chemical bonds and molecular position occurs in them. This alteration in bonds and molecular position results in the formation of a new substance.
In a chemical reaction, the substances which are responsible for interacting with each other are called the Reactants.
In a chemical reaction, the new substances those are formed are called the Products.
A Chemical Reaction can be represented as follows:

W + X → Y + Z.

Here, W and X are reacting to form Y and Z.
So, W and X are the Reactants.
Y and Z are the Products.
As the Reactants react to form the Products, so the arrow → is represented from the Reactant to the Product.
In the given question,

glucose + fructose → sucrose + water

As arrow → always direct from Reactants to the Products, so the left side of the arrow will be the reactants and the right side of the arrow will be the products.
Hence, the Reactants are Glucose and Fructose.
The Products are Sucrose and Water.
So, Glucose and Fructose undergo chemical reaction to form Sucrose and Water.
