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.
Answer:
The described anatomical features belong to <em>Homo habilis.</em>
Explanation:
<em>Homo habilis´ </em>skull reflects its large and developed brain, compared to australopithecines.
Specimens of the species characterized by having a large skull and rounded braincase, due to the <em>size of the brain</em>. Their <em>forehead</em> was <em>slightly appearing</em>. They also presented the <em>facial projection reduced</em>. Their <em>faces were flat</em> with a <em>shallow slope </em>from the nose to the teeth, with a poorly developed brow ridge. They had small jows and <em>reduced chin</em>, as well as small teeth and molar increasing toward the back. The hole in the center of the skull, where it fitted the spinal cord, is reflections of their <em>walking habits on two legs</em>.
