The earth magnetic field changes direction and its strength varies from year to year. This results in magnetic anomalies within a rock body as magnetic elements and minerals records the changing direction of the magnetic field.

As new magma is brought near the mid-oceanic ridge, the older ones are pushed backwards and they show a different magnetic field direction from the cooling magma. This is usually evident in the orientation of the magnetic minerals.

What happens before mitosis occurs?
bonufazy [111]

Answer:

The correct answer would be C.) The cell grows and makes a copy of its genetic material.

Cell cycle can be divided into two phases namely; inter-phase and mitotic phase.

Inter-phase or resting phase is the phase occurs between two consecutive mitotic phases.

It is sub-divided into three phases:

Gap 1 (G₁) phase: The cell actively performs its functions during this phase. It grows in size, transcribe and translate all the enzymes, proteins and other components which are necessary for replication of DNA (deoxyribonucleic acid).

Synthesis (S) phase: It is the phase during which DNA content of the cell is replicated or synthesized. After this phase, the DNA content of the cell doubles however, the chromosome number remains the same.

Gap 2 (G₂) phase: The cell resumes its growth and prepares itself for cell division or mitotic phase. The cell organelles like mitochondria and chloroplasts (in plants) also divide during this phase. The cell continues to grow until it enters mitotic phase.

Hence, we can conclude that the cell grows and makes copy of its genetic material ( usually DNA) before mitosis.
