If |an |adult |human |being |loses |an |arm |in |an |accident, |it |does |not |regrow. |Why |not? |
A. |Cell |division |does |not |occur |in |adults |
B. |Damaged |tissues |are |not |repaired |in |adults |
,C. |Old |cells |in |your |organs |are |never |replaced |by |newer |cells |
D. |Developmental |processes |for |growing |limbs |are |not |reactivated |when |a |limb |is |lost |later |in |
life |
E. |When |the |person's |arm |is |lost, |so |are |the |person's |genes |for |growing |an |arm. |- |CORRECT |
ANSWER✔✔-D. |Developmental |processes |for |growing |limbs |are |not |reactivated |when |a |limb |
is |lost |later |in |life.
During |Interphase, |are |the |cells |dividing? |- |CORRECT |ANSWER✔✔-No
What |are |the |three |stages |of |Interphase? |- |CORRECT |ANSWER✔✔-1. |G1- |Growth
2. |S- |Synthesis
3. |G2- |Growth
Which |of |the |following |statements |about |interphase |is |false?
A. |DNA |is |replicated |during |interphase.
B. |Very |few |of |our |cells |are |in |interphase |at |any |one |time.
C. |Cells |can |remain |in |interphase |until |their |demise.
D. |Growth |of |the |cell |happens |during |Interphase.
E. |Cells |can |halt |their |progress |in |the |cell |cycle |by |going |from |G1 |to |G0 |- |CORRECT |
ANSWER✔✔-B. |is |false.... |Interphase |takes |up |most |of |the |cell |cycle
Who |has |the |highest |percentage |of |cells |in |S |phase?
A. |A |body |builder
B. |An |adult |cancer |patient
C. |A |fetus
D. |A |sumo |wrestler |- |CORRECT |ANSWER✔✔-C. |A |fetus... |the |key |word |here |is |"percentage." |
The |entire |fetus |is |growing; |cancer |is |in |only |one |part |of |the |body.
, Name |the |stages |of |Mitosis: |- |CORRECT |ANSWER✔✔-1. |Prophase
2. |Prometaphase
3. |Metaphase
4. |Anaphase
5. |Telophase
(PPMAT)
In |what |phase |of |the |cell |cycle |does |the |cell |divide? |- |CORRECT |ANSWER✔✔-Mitosis
What |is |mitosis |vs. |cytokinesis? |- |CORRECT |ANSWER✔✔-- |Mitosis: |Division |of |the |nucleus |and |
nuclear |material
-Cytokinesis: |Division |of |the |rest |of |the |cell
During |what |phase |does |the |replication |of |DNA |occur? |- |CORRECT |ANSWER✔✔-S |phase |of |
Interphase
During |what |phase |do |chromosomes |duplicate? |- |CORRECT |ANSWER✔✔-S |phase |of |
Interphase
During |what |phase |do |sister |chromatids |separate? |- |CORRECT |ANSWER✔✔-Mitotic |phase
Suppose |that |at |the |end |of |G2 |phase, |a |skin |cell |(in |some |species |of |mammal), |has |16 |
chromatids |total. |How |many |chromosomes |will |each |cell |produced |form |from |this |cell |have |
after |mitosis |and |cytokinesis |are |complete?
