Question: The Process of the cell cycle where the nucleus divides to create two identical nuclei is called?
A. interphase B. DNA C. mitosis D. mutation |
ANSWER: C MITOSIS
mitosis is the process where the nucleus divides making TWO IDENTICAL NUCLEI |
|
|
QUESTION: During PROPHASE, the two centrioles_____________?
A. disintergrate during the process B. move to opposite ends of the cell C. turn into chromosomes D. help plant cells develop |
ANSWER: B- move to OPPOSITE ENDS of the cell
as centrioles MOVE APART during PROPHASE, spindle fibers are formed and stretched ACROSS THE CELL |
|
|
Question; Which of these is a part of the cell that contains HEREDITARY MATERIAL?
A. chromosomes B. interphase C. mitosis D. embryro |
ANSWER: A- CHROMOSOMES
CHROMOSOMES contain HEREDITARY MATERIAL |
|
|
Question: The FINAL step in the MITOSIS PROCESS for ANIMAL CELLS is _____________?
A. interphase B. centrioles C. telephase D. chromosomes |
ANSWER: C- TELOPHASE
during TELOPHASE the FINAL STEP in MITOSIS the CYTOPLASM begins to SEPARATE so that each of the TWO NEW CELLS will begin MITOSIS |
|
|
Question: In ASEXUAL reproduction, offspring are produced____________?
A. from one parent B. from two parents C. from 46 chromosomes D. from 48 chromosomes |
ANSWER: from ONE PARENT
ASEXUAL REPRODUCTION the offspring has only ONE PARENT so its hereditary material is EXACTLY THE SAME as the parent |
|
|
Question; A sea star has one of its arms broken off.That arm grows into its own separate organism through________?
A. sexual reproduction B. regeneration C. spindle fibers D. chromosomes |
ANSWER: B REGENERATION
REGENERATION allows some organisms to REGROW a body part as well as to allow a new organism to develop from a piece of a body part |
|
|
Question; Hydra reproduce through __________ where the offspring grows from the body of the parent organism
A. budding B. DNA C. thymine D. mutations |
ANSWER: HYDRA
HYDRA reproduce through BUDDING |
|
|
Question: Which of these ia a part of ASEXUAL REPRODUCTION?
A. sperm B. egg C. zygote D. regeneration |
ANSWER: D REGENERATION
Organisms such as sponges use regeneration for ASEXUAL REPRODUCION |
|
|
Question; When MITOSIS takes place, the DNA code in the nucleus is __________ and passed to the new cells.In this way, new cells receive the _______ coded information that was in the ______ _______.
A. copied, different, different cell B. copied,same,original cell |
ANSWER: B- copied, same, original cell
|
|
|
Question: DNA controls the ______ of cells with ___________ instructions

Question: The process by which DNA copies itself is such the two strands of DNA __________ and ___________.Each strand the becomes a pattern on which a ___ strand is formed.
A. wind, come together, old B. unwind, separate, new |
ANSWER: B unwind, seperate, new
The process by which DNA copies itself is such the two strands of DNA UNWIND and SEPERATE. Each strand becomes a pattern on which a NEW strand is formed. |
