Answer:

A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it. The most likely materials are crystalline silicon, amorphous silicon, gallium arsenide and organometallics (soluble platinum).

Match the given behaviors of water with their correct rationale. Use your observations about water and the reading you have done
kap26 [50]

Answer:

Heat energy first breaks hydrogen bonds before it increases movement of water molecules - High specific heat

As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water- Ice floats on water

A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not - High heat of vaporization

Hydrogen bonds between water molecules keep the molecules "sticking together." - Cohesion

Explanation:

Water is a molecule composed of two atoms of hydrogen and one atom of oxygen. Water is a very unique substance with properties that are unexpected of a molecule its size. Some of the unique properties of water include:

Its high polar nature, High-specific heat, High heat of vaporization, the lower density of ice. One of the reason for these unique properties is strong cohesive forces between water molecules.

Cohesion: Hydrogen bonds between water molecules keep the molecules "sticking together."

Polarity: Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen because oxygen is more electronegative than hydrogen. As a result, water is a good polar solvent.

High specific heat: Heat energy first breaks hydrogen bonds before it increases movement of water molecules.

Lower density of ice: As water freezes, the hydrogen bonds form a crystalline lattice which keeps the molecules at a consistent distance leading to a density lesser than liquid water, therefore, ice floats on water

High heat of vaporization: A large amount of energy is needed to convert liquid water, where the molecules are tied by hydrogen bonds, to water vapor, where they are not.

Which process makes it possible for the body to grow and repair? Meiosis Sexual reproduction Replication Mitosis
ArbitrLikvidat [17]
Meiosis sexual reproduction only occurs in the gametes, which do not contribute to the body's growth and repair, only reproduction.
Replication mitosis, however, produces diploid cells identical to the parent/mother cell, which aids in the body's growth and repair.
