dmitriy555 [2]

Dominant allele

Explanation:

An allele whose trait shows up in an organism when the allele is present is called a dominant allele.

An allele whose trait does not show up in an organism when present is called a recessive allele.

  • An allele is the two possible forms of gene.
  • A gene can be dominant or recessive in nature.
  • An allele is a DNA that occupies a particular locus on a chromosome.
  • They usually occur in pairs.

Sodium explodes when it contacts water. If I have a compound that contains sodium, will it explode if it is exposed to water?
Vaselesa [24]

Answer:

Option D = No, when elements combine to form a new material, they have properties unique to the new materials.

Explanation:

When sodium contact with water it loses its one electron and thus gain positive charge. When there are more sodium atoms present and many atoms do this thus more positive ions are produced and these positive ions repeal each other at high speed and explosion occur.

But when it form compound with other material, it will not showed this behavior.

Example:

Consider the sodium chloride, when it dissolve in water sodium not showed explosion. In sodium chloride sodium already gives its electron to the chlorine and have stable electronic configuration. The sodium present in cationic form. When it dissolve, partial positive charge of water surrounds the Cl⁻ and partial negative charge of water surrounds the Na⁺ ion, ans sodium chloride gets dissolve into water without explosion.

Compared to a 1.0-liter aqueous solution with a pH of 7.0, a 1.0-liter aqueous solution with a pH of 5.0 contains
grin007 [14]

Answer:

2. 100 times more hydroxide ions,

Explanation:

Acidity and alkalinity are measured with a logarithmic scale called pH. Each one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. Therefore, a 1.0 liter aqueous solution with a pH of 5.0 contains 100 times more hydronium ions than a 1.0 liter aqueous solution with a pH of 7.0
