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

A. places, same
B. activities, coded
ANSWER: B-

DNA controls the ACTIVITIES of cells with CODED instructions
Question; What does a DNA model look like?

A. A sprial staircase
B. stairs
ANSWER: A. sprial staircase
Question: What are the four nitrogen bases?(HINT)
A
G
C
T
ANSWER: A- adenine
G- guanine
C- cytosine
T- thymine
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.
