Human somatic cells contain 46 chromosomes. A scientist finds a cell in a bone marrow sample that contains 92 chromosomes. What must be true about this cell? A. The cell has just completed mitosis.
B. The cell has suffered a genetic mutation and may be cancerous.
C. The cell is in the first growth phase G1 of interphase
D. The cell is in the second growth phase G2 or mitotic (M) phase.

D. The cell is in the second growth phase

Explanation:

Mitosis is the process of dividing the cell's nucleus to produce two genetically identical nuclei. Since a normal cell (with a single nucleus) has 46 chromosomes, then a replica of that nucleus would mean an additional 46 chromosomes, which is a total of 92 chromosomes. I also took the test and got a 5/5 so I know it's right.

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
