Total questions: 14
Worksheet time: 10mins
Which structure is correctly paired with its function?
ovary — provides milk for newborns
testis — development of sperm
placenta — storage of released eggs
uterus — produces estrogen
Which sequence represents the path of sperm leaving the body?
A --> C --> G
A --> C --> B
E --> F --> H
D --> F --> G
Which diagram best represents part of the process of sperm formation in an organism that has a normal chromosome number of eight?
A reproductive system is represented in the diagram.
If an injury occurred to the structure labeled C, the most likely result would be a problem with
delivery of sperm
production of gametes
production of hormones
excretion of urine
Which situation would be part of the normal reproductive cycle of a human?
the presence of testosterone regulating gamete production in a male
estrogen in concentrations that would produce sperm in a female
a high progesterone level in a male
a low insulin level in either a male or a female
Removal of one ovary from a human female would most likely
affect the production of eggs
make fertilization impossible
make carrying a fetus impossible
decrease her ability to provide essential nutrients to an embryo
The human female reproductive system is represented in the diagram.
Production of gametes and support of the fetus normally occur in structures
1 and 2
2 and 4
3 and 5
4 and 5
This graph represents hormones and events in the
process of fetal growth and development
process of meiotic cell division during sperm development
reproductive cycle of males
reproductive cycle of females
In humans, egg cells are usually fertilized in the
vagina
uterus
oviduct
ovary
The diagram below summarizes some of the steps in the development of humans.
All the genetic information needed for the organism to develop is first present at
A
B
C
D
The diagram represents a stage in the development of a fetus.
A major function of structure X is to
produce gametes by meiosis
protect the fetus from physical injury
exchange materials between the mother and the fetus
store food to provide the fetus with nutrients
Although all the body cells in an animal contain the same hereditary information, they do not all look and function the same way. Which step of differentiation causes this to occur?
embryonic cells use different portions of their genetic information
the number of genes increases as embryonic cells move to new locations
embryonic cells delete portions of chromosomes
genes in embryonic body cells mutate rapidly
Which row in the chart shows the correct sequence for processes 1, 2, and 3 based on the diagram of embryo formation
Row 1
Row 2
Row 3
Row 4
For a human zygote to become an embryo, it must undergo
fertilization
mitosis
recombination
meiosis
