Answer: magnetism, electrical conductivity, high melting point

Explanation: Physical properties of metals include: ductility, magnetism, malleability, high electrical conductivity, high density, high melting and high boiling point.

Magnetism is the property of metals which makes them to be attracted by magnets.

Metals are good conductors of electricity because their valence electrons are free to move through out the solid.

Metals have high melting points because of the strong bonds existing between valence electrons and nuclei. High energy is required to break the strong bonds between the nucleus and the valence electrons in order for the metals to melt. This means that metals melt at high temperatures.

Answer:

D. magnetism, electrical conductivity, high melting point

Explanation:

Magnetism is the property of metal due to which they are attracted by magnets. Metals have high electrical conductivity which means they are good conductors of electricity. They also have high melting points i. e. they require high amount of heat to change its solid state into liquid state. In melting, bonds are broken down due to the applicable of heat energy.

9. Based on the information in the table, which enzyme is not functioning in this strain of mold?
Sedbober [7]

Based on the information in the table,

  • the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
  • the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.

<h3>What are enzymes?</h3>

Enzymes are organic catalysts that speed up the chemical reactions occurring in the body.

Enzymes are very essential in most metabolic reactions occurring in the body.

The deficiency or inactivity of an enzyme in the body will lead to an accumulation of the substrate on which the enzyme acts on.

Based on the information in the table,

  • the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
  • the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.

in conclusion, enzymes are important for biochemical reactions.

Why are ammonite fossils found in the Himalayas?
sertanlavr [38]

Answer;

This is because most likely some time a ago there use to be Ammonites living there and as they died there, they got fossilized.

Explanation;

-Fossils of a marine animal called Ammonite are found in large numbers in the Kali Gandaki river in Nepal. Ammonites were sea animals having shells - either straight or coiled. When the Tethys sea disappeared, they were caught in the shale layers of clay and transformed into fossils. This is one of the proofs that the Himalayas were indeed once under water.
