week 12

Question 1

sperm goes from

Answer 1

vagina
to cervix
to uterus
to the fallopian tube
to the ovum

Question 2

ovum is released from the

Answer 2

ovary

to

the fallopian tube to get fertilized, then plant itself in the womb

Question 3

when the duplication of cell material in ‘ciliate division’ is complete

Answer 3

the cell walls close in preparation for fission

then the Ciliate divides into two equate parts

Question 4

total time for cell division

Answer 4

“30 minutes”

Question 5

meiosis

Answer 5

the process that generates gamines

Question 6

gamines

Answer 6

sexual reproduction cells (eggs and sperm)

Question 7

within the nucleus of a testicle diploid cell

Answer 7

the chromosomes are dispersed

Question 8

diploid chromosomes are dispersed until…

Answer 8

meiosis begins

Question 9

there are two copies of each…

Answer 9

chromosome

Question 10

each pair of chromosomes are called a

Answer 10

homologous pair

Question 11

red chromosome from the…

Answer 11

maternal parent

Question 12

blue chromosome from the…

Answer 12

paternal parent

Question 13

during interphase

Answer 13

chromosomes duplicate inside the nucleus

Question 14

interphase show that each chromosome

Answer 14

has identical sister chromotids attached at the centromere

Question 15

meiosis 1 begins with

Answer 15

prophase 1

Question 16

prophase 1

Answer 16

chromosomes become condensed

homologous chromosomes pair up

Question 17

crossing over

Answer 17

an event that can happen during chromosomes being condensed,

in which the genes of the chromosomes will combine in strange and new ways

Question 18

after meiosis 1, prophase 1 comes…

Answer 18

meiosis 1, metaphase 1

Question 19

metaphase 1

Answer 19

the nuclear envelope is broken down

the spindle spans across the cell, connecting both ends of the cell

as well as attaching to, and aligning, the homologous pairs

Question 20

the spindle grows

Answer 20

as both ends of the cell synthesizes tubulin protein, creating mictrotubules

Question 21

attached to each chromosomes centromere is

Answer 21

a kinetocore

Question 22

kinetocore

Answer 22

part of the chromosome that attaches to, and moves along, microtubules

Question 23

microtubules

Answer 23

the strings of protein that connects to a homologs kinetocore

Question 24

after meiosis 1, metaphase 1 comes…

Answer 24

meiosis 1, Anaphase 1

Question 25

in meiosis 1, Anaphase 1

Answer 25

members of homologous pairs disconnect from each other,

causing the altered chromosomes in each half to pull pulled over to either spindle

Question 26

after meiosis 1, Anaphase comes…

Answer 26

Meiosis 1, Telophase

Question 27

Meiosis 1, Telophase

Answer 27

the two spindles drift apart, taking their chromosomes with them, they both separate to create 2 cells

Question 28

after Meiosis 1, Telophase comes

Answer 28

Meiosis 2, Prophase 2

Question 29

Meiosis 2, Prophase 2

Answer 29

now, in the two cells, prophase happens all over again

chromosomes condense in both cells’ nuclei, further obscuring genes

homologous chromosomes pair up

Question 30

Meiosis 2, Metaphase/Anaphase 2

Answer 30

the spindle still attaches to chromosomes, but there are now half as many.

the sister chromotids are separated by the spindle

Question 31

Meiosis 2, Telophase 2

Answer 31

another division creates 4 cells in total, the chromosomes now being split into the 4 different cells.
