Answer
-
chromosome
-
together

Question 13
Question
A diploid is [blank_start]two[blank_end] sets of chromosomes; [blank_start]one[blank_end] from dad and [blank_start]one[blank_end] from mom. Diploid human cells have [blank_start]46[blank_end] chromosomes.
Question 14
Question
A haploid is [blank_start]one[blank_end] set of chromosomes. Haploid human cells have [blank_start]23[blank_end] chromosomes.
Question 15
Question
A chicken has a diploid # of 78 chromosomes. The haploid number is [blank_start]39[blank_end].
Question 16
Question
Peas have a haploid # of 7 chromosomes. Their diploid number is [blank_start]14[blank_end].
Question 17
Question
The cell cycle is the [blank_start]stages[blank_end] of [blank_start]life[blank_end] that cells go through as they [blank_start]grow[blank_end] and [blank_start]develop[blank_end].
Question 18
Question
[blank_start]Interphase[blank_end] is the period of time that occurs between cell divisions.
Question 19

g1
-
S
-
G2
-
Mitosis
-
Cytokinesis
-
Interphase
-
M phase
-
Prophase
-
Metaphase
-

-
Telophase
Question 21
Question
Label the stages.
Answer
-
Anaphase
-
Interphase
-
Metaphase
-
Prophase
-
Telophase
Question 22
Question
Cell spend most of their time in [blank_start]interphase[blank_end].
Question 23
Question
Interphase consists of [blank_start]three[blank_end] parts: [blank_start]G1[blank_end], [blank_start]S[blank_end], and [blank_start]G2[blank_end].
Question 24
Question
During prophase the centrioles [blank_start]separate[blank_end] and [blank_start]spindle[blank_end] begins to form. The chromosomes begin to [blank_start]condense[blank_end] and the [blank_start]nuclear[blank_end] [blank_start]membrane[blank_end] begins to break down.
Answer
-
separate
-
spindle
-
condense
-
nuclear
-
membrane
Question 25
Question
During metaphase the chromosomes [blank_start]line[blank_end] up single file in the [blank_start]middle[blank_end] of the cell. The spindle fibers attach to the [blank_start]centromere[blank_end] region.
Question 26
Question
During anaphase the spindle fibers begin to pull on the [blank_start]centromeres[blank_end] causing the sister chromatids to pull [blank_start]apart[blank_end] and move to [blank_start]opposite[blank_end] poles of the cell.
Answer
-
centromeres
-
apart
-
opposite
Question 27
Question
During telophase the nuclear membrane begins to [blank_start]form[blank_end] again around single [blank_start]chromosomes[blank_end], the chromosomes begin to [blank_start]decondense[blank_end] and [blank_start]cytokinesis[blank_end] begins.
Answer
-
form
-
chromosomes
-
decondense
-
cytokinesis
Question 28
Question
During cytokinesis the cell [blank_start]membrane[blank_end] pinches inward, [blank_start]cytoplasm[blank_end] divides into two [blank_start]daughter[blank_end] cells, and the cells begin to enter [blank_start]interphase[blank_end].
Answer
-
membrane
-
cytoplasm
-
daughter
-
interphase
Question 29
Question
During G1 the cell is [blank_start]growing[blank_end] and making [blank_start]proteins[blank_end]. During S the chromosomes are being [blank_start]replicated[blank_end] and during G2 the cell continues to [blank_start]grow[blank_end] and prepares to [blank_start]divide[blank_end].
