• the planet that moves around the Sun at the largest speed is Mercury
• ***
• Mercury is the fastest planet, which speeds around the sun at 47.87 km/s.
• In miles per hour, this equates to a whopping 107,082 miles per hour.

Explanation

Cytosine does not form a bond with adenine because its hydrogen bond donors and acceptors are not complementary.

Cytosine typically forms three hydrogen bonds with guanine, whereas adenine forms two hydrogen bonds with thymine.

The patterns of hydrogen bonding in cytosine and adenine do not match, preventing the formation of a stable pair.

Explanation

Bleach is commonly used as a disinfectant to prevent the spread of illness and disease.

Bleach:

Typically, household bleach contains sodium hypochlorite, which is effective at killing bacteria, viruses, and fungi.

It is widely used in cleaning and disinfecting surfaces, laundry, and water to eliminate harmful microorganisms and reduce the risk of infection.

Enzymes act as biological catalysts, speeding up chemical reactions in the body without being consumed in the process.

They are essential for various physiological processes, including digestion and metabolism.

Explanation

The hardest substance in the world is diamond.

Its hardness is due to the strong covalent bonding between its carbon atoms.

This making it the most resistant to scratching.

Explanation

Internal energy is primarily a function of temperature.

For a given substance, internal energy (U) is related to the temperature of the system, as it reflects the kinetic and potential energy of the molecules.
