Question

Hello I really need help with these BIO-1 questions. Could you guys please answer all of the multiple choice questions. I know it seems like a lot but i would highly appreciate it becuase i really need help on them. Thank you guys! I truly appreciate it.

22. During meiosis, at the end of which part of meiosis, are the sister chromatids separated from one another A. Meiosis I B. Meiosis II C. Both Meiosis I and meiosis II D. None of the above 23. Which of the following contains useful energy for the cel A. ATP B. NAD+ C. proton gradient D. A and C E. B and C 24. DNA replication is called as semi-conservative because A. all organisms use the same AT/GC base pairing rules B. each of the two daughter DNA molecules formed after replication contains one parental DNA strand and one newly synthesized C. each of the two daughter DNA molecules formed after replication D. One DNA molecule retains both parents strands whereas the other E. Each DNA molecules contains sections of parental strands and strand contains two newly synthesized DNA strands DNA molecule contains two new strands sections of newly synthesized strands 25. During which phase of mitosis are the sister chromatids being pulled toward the opposite poles after they have completely separated from each other: A. Prophase B. Prometaphase C. Metaphase D.Anaphase 26. Cellular respiration can best be described as: A. using energy released from breaking high-energy covalent bonds in organic molecules to force ATP formation from ADP and phosphate. B. taking electrons from food and giving them to phosphate to make ATP C. taking electrons from food and giving them to oxygen to make water, using the energy released to drive ATP formation. D. converting higher-energy organic molecules to lower-energy organic molecules and using the energy released to drive ATP formation.

Explanation / Answer

22. During meiosis at the end of the meiosis II sister chromatids are separated. Thus the correct option is:

B: Meiosis II

23. The following contains useful energy for the cell:

A: ATP and

C: Proton gradient that is used to synthesize ATP. Thus the correct option is:

D: A and C

24. DNA replication is called semi conservative because:

B: each of the two daughter DNA molecules formed after DNA replication contains one parental DNA strand and one newly synthesized DNA strand. Correct option is: B

25. During mitosis, the sister chromatids are pulled towards the opposite poles after they have completely separated from each other during:

D. Anaphase. The correct option is: D

26. Cellular respiration can be best described as:

C. taking electrons from food and giving them to oxygen to make water; using the energy released to drive ATP formation. The correct option is:C
