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.

liq [111]
<span>In grafting, the plant with desired root system is called the <u>rootstock</u>, and the portion of the plant with the buds is called the <u>scion</u>.

The grafting is a horticultural technique in which parts from two or more plants are joined together to grow as a one single plant.
Rootstock is the plant selected for its roots because it can provide different properties, such as fruit size, or because it is resistant to drought or diseases. 
Scion is the plant selected for its leaves, flowers, fruits or stems.

The term respiration describes the exchange of gases between your blood and the air. Cellular respiration ________.
kotegsom [21]

Answer:

The term describes cellular respiration

Explanation:

Cellular respiration, also known as internal or tissue respiration can be represented by the equation:

C6H12O6 + 6H2O ---> 6H2O + 6CO2 + Energy (in form of ATP)

From the equation, glucose from the blood is oxidized by oxygen trapped from the air by the nostrils. The main purpose of cellular respiration is to generate energy required by the body for various life activities
