Answer:
DNA replication occurs through the help of several enzymes. These enzymes unzip DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created.
Explanation:
The correct answer is : Movement Use energy Maintain homeostasis Composed of cells.
Explanation:
There are several qualities of living things that are familiar to all living things. These properties of living things include: Are made up of one or more cells, can reproduce, produce and generate, obtain and use energy, and react to their environment.

Answer:
The diagram is attached below.
Explanation:
when sodium and chlorine comes close together they form anion and cation. The compound formed is called sodium chloride.
Both atoms bonded together through ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
The period when an embryo of a seed is alive but no longer growing is considered to be in it's dormant stage. During dormancy, they seed is restricted from growing due to environmental conditions such as limited sunlight, water or unfavorable temperatures.
