What are the differences between DNA and RNA?

STALIN [3.7K]

Summary of Differences Between DNA and RNADNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring.DNA is a double stranded molecule while RNA is a single stranded molecule.DNA is stable under alkaline conditions while RNA is not stable.DNA and RNA perform different functions in humans. DNA is responsible for storing and transferring genetic information while RNA directly codes for amino acids and as acts as a messenger between DNA and ribosomes to make proteins.

\85. compare the equation for cellular respiration to the equation for photosynthesis.

Alexandra [31]

Answer: The reactants for Photosynthesis are the products for Cellular Respiration and the reactants of Cellular Respiration are the products of Photosynthesis.

Photosynthesis:

6CO2 + 6H2O -> C6H12O6 + 6O2

**6 Carbon Dioxide + 6 water -> Glucose + 6 Oxygen**

Cellular Respiration:

C6H12O6 + 6O2 -> 6H2O + 6CO2 + Energy

**Glucose + 6 Oxygen -> 6 Water + 6 Carbon Dioxide + Energy**

What does a scientist observe in a chemical's reaction rate? the speed at which the reactants change to products over a given ti

kvasek [131]

Answer:

The speed at which the reactants change to products over a given time.

Explanation:

A chemical's reaction rate is the change in the concentration of a reactant or a product with time (in moles per second).

Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:

reactants → products

Therefore, the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.

According to the temperature and other parameters, the reaction rate can increase or decrease.
