Biology Test Answers Essay

At which phase are controllers beginning to move apart in animal cells? E. Proposes This answer can be found in the book on page 232, “Proposes – compresses move away from each other, propelled partly by the lengthening misconstrues between them. ” 4. ) If cells in the process of dividing are subjected to chocoholic, a drug that interferes with the formation of the mitotic spindle apparatus, at which stage will mitosis be arrested? D.

Metastases This answer can be found on page 233, Figure 12. . 5. ) Where do the misconstrues of the spindle originate during mitosis in animal cells? B. Cumbersome This answer can be found on page 232, “Proposes – The mitotic spindle begins to form. IT is composed of the compresses and misconstrues that extend from them. ” 6. ) Tax is an anticancer drug extracted from the pacific yew tree. In animal cells, Tax disrupts microcircuit formation by binding to misconstrues and accelerating their assembly from the protein precursor, tubing.

Surprisingly, this stops mitosis. Specifically, Tax must affect… A. Formation of the mitotic spindle This answer is A, because the drug Tax disrupts microcircuit formation, without microcircuit formation the mitotic spindle will not be able to form. 8. ) Why do chromosomes coil during mitosis? B. To allow the chromosomes to move without becoming entangled and breaking This answer can be found in the book on page 229, Figure 12. 3. 12. ) Which of the following is true concerning cancer cells? E.

When they stop dividing, they do so at random points in the cell cycle; they are not subject to cell cycle controls; and they do to exhibit density-dependent inhibition when growing in culture. This answer can be found in the book on page 241, Figure 12. 19. 15. ) What is the correct chromosomal condition at the Promethean of mitosis? This answer can be found on page 232, Figure 12. 7. 16. ) What is the correct chromosomal condition for one daughter nucleus at telephone of mitosis? 17. ) If the cell whose nucleus material is shown in Figure 12. Continues toward completion of mitosis which of the following events would occur next? B. Spindle fiber formation This answer can be Dunn on page 233, Figure 18. ) What might be among the research team’s conclusions? B. The elderly persons’ samples demonstrated their lowered immune systems This answer is B, because the elderly persons’ immune system are lowered, because they are old and their cells have stopped dividing, causing the rest of the body to not repair itself. 19. ) Which of the following investigations might be most productive to show what data on the teenagers might indicate?

C. Test female teens at different times in their menstrual cycle This answer is C, cause the body is striping the lining of the uterus and isn’t paying attention to the pathogen introduction which means the body’s immune system is lowered during these points of time. 20. ) When a cell is in anapest of mitosis, which of the following will he see? C. Individual chromatics separating This answer can be found in the book on page 233, Figure 12. 7. 21 . ) When the cell has Just completed telephone, which of the following will he see? E.

Two small cells with chromatin This answer can be found in the book on page 233, Figure 12. 7. 24. The human genome is minimally contained in which of the following? A. Every human cell This answer can be found in the book on page 250, Figure 13. 3 26. ) Which of the following is a true statement about sexual vs. asexual reproduction? B. In sexual reproduction, individuals transmit 50% of their genes to each of their offspring. This answer can be found in the book on page 251, “Human life cycle begins when a haploid sperm fuses with a haploid egg from the mother. ” 29. Which of the following is true of a species that has a chromosome number of an = 16? C. Each cell has 8 homologous pairs This answer is C, because the species has half of its mother’s info and the other half its father’s meaning it has 8 homologous pairs.
