A student claims: 'Menstruation means that fertilisation has happened.' Why is this statement incorrect?

Menstruation involves an unfertilised egg

Menstruation occurs only after fertilisation

Menstruation produces sperm

Menstruation means a baby is developing

Which pair of changes provides the strongest evidence that puberty is preparing the body for reproduction?

Production of sperm in boys and development of ova in girls

Growth in height and oily skin

Growth of hair and pimples

Broader shoulders and wider hips

Two students are the same age. One has started puberty while the other has not. Which conclusion is most appropriate?

This can be normal because puberty starts at different ages

The student who has not started puberty cannot develop normally

Puberty always starts at exactly the same age

The student who started puberty must be older

Which observation would provide evidence that puberty is controlled by hormones rather than simply by growth in height?

Several different body changes occur at the same stage of development

A person becomes taller

A person becomes heavier

A person's shoes become larger

A girl menstruates. Which conclusion can be made from the information provided?

An unfertilised egg has been released together with the uterine lining

Fertilisation definitely occurred

A baby is developing in the uterus

The ovaries have stopped working

A fertilised egg is found developing in the uterus. Which event must have occurred before this?

A sperm joined with an ovum

Menstruation occurred

Sperm were produced by the ovary

The uterus released sperm

Which comparison between sperm and ova is correct?

Both are sex cells, but sperm are male sex cells and ova are female sex cells

Both are produced by testes

Both are produced by ovaries

Sperm are female sex cells and ova are male sex cells

A student's diagram labels the ovary as the place where the baby develops. Which correction is needed?

The uterus is where the baby develops; the ovary produces ova

The oviduct is where the baby develops; the ovary produces sperm

The birth canal is where the baby develops

The testis is where the baby develops

A blockage occurs in the sperm duct. What is the most likely consequence based on its function?

Sperm cannot be carried towards the penis

Ova cannot be produced

The baby cannot develop in the uterus

Menstruation immediately stops

A blockage occurs in the oviduct. Which process would most directly be affected?

Fertilisation

Production of ova

Development of the baby in the uterus

Production of sperm

Which sequence correctly follows the pathway of the female reproductive process described in the text?

Ovary → oviduct → uterus

Uterus → ovary → oviduct

Oviduct → ovary → uterus

Birth canal → ovary → uterus

Which diagram correctly represents the relationship between the male reproductive structures?

Testis → sperm duct → penis

Penis → testis → sperm duct

Sperm duct → uterus → testis

Testis → uterus → penis

A scientist wants to identify whether a physical change is associated with puberty in both sexes. Which observation would provide the strongest evidence?

Both boys and girls show increased body hair

Only boys produce sperm

Only girls menstruate

Only girls develop breasts

Consider these statements: 1. Boys produce sperm during puberty. 2. Girls develop ova during puberty. 3. Both boys and girls can experience growth spurts. 4. Only girls experience hormonal changes. Which combination is correct?

1, 2 and 3 only

1 and 4 only

2 and 4 only

1, 2, 3 and 4

A girl experiences growth, increased body hair and oily skin. Later, she begins menstruation. Which conclusion is best supported?

Her reproductive system has undergone changes associated with puberty

She has already fertilised an egg

She is producing sperm

Her uterus has stopped functioning

A boy has begun producing sperm but has not yet developed all the physical characteristics of an adult. What does this demonstrate?

Puberty occurs gradually in stages

All puberty changes happen simultaneously

Sperm are produced before puberty

Physical development stops once sperm are produced

Which statement best explains why hormones are important during puberty?

They cause the physical changes associated with puberty

They carry sperm through the sperm duct

They form the uterus

They cause all eggs to become fertilised

Why might puberty begin at different ages in different people?

Puberty does not begin at exactly the same age for everyone

Everyone begins puberty at exactly the same age

Only boys experience puberty

Hormones are not involved in puberty

A student groups puberty changes into 'boys only', 'girls only' and 'both'. Which should be placed in the 'both' group?

Oily skin and growth of body hair

Menstruation and sperm production

Broader shoulders and wider hips

Deeper voice and breast development

Which change is specifically described for girls?

Hips become wider and breasts develop

Testes begin producing sperm

Shoulders become broader

Voice becomes much deeper

Which change is specifically described for boys?

Voice becomes deeper and shoulders become broader

Hips become wider and breasts develop

Menstruation begins

Ovaries begin producing ova

Which pair contains changes that can occur in both boys and girls?

Growth spurt and increased body hair

Menstruation and sperm production

Breast development and sperm production

Broader shoulders and menstruation

What happens to menstruation if an egg is fertilised?

Menstruation stops

Menstruation becomes more frequent

Sperm production stops

The ovaries disappear

A girl has not become pregnant. Her menstrual cycle continues approximately once a month. Which statement best explains this?

An unfertilised egg is released together with the lining of the uterus

A sperm is released every month

The uterus produces sperm

The ovaries stop producing ova

A fertilised egg eventually develops into a baby. Which organ provides the place where the baby develops?

Uterus

Ovary

Oviduct

Sperm duct

Where does fertilisation take place according to the information given?

Oviduct

Uterus

Ovary

Birth canal

Which structure receives sperm from the male?

Birth canal

Ovary

Uterus

Testis

A sperm needs to travel from the testis towards the penis. Which structure carries it?

Sperm duct

Uterus

Oviduct

Ovary

Which sequence correctly describes reproduction?

Sperm + ovum → fertilisation → development of a baby

Ovum → sperm → fertilisation → puberty

Sperm → menstruation → ovum → baby

Puberty → menstruation → sperm → fertilisation

A girl's ovaries begin developing ova during puberty. What is the significance of this change?

Her reproductive system is developing the ability to produce female sex cells

Her uterus disappears

She begins producing sperm

Fertilisation has already happened

A boy's body begins producing sperm. What does this indicate?

He has reached a stage of puberty

He has stopped growing

He has begun menstruating

His reproductive system is no longer working

Why does the reproductive system change during puberty?

It becomes able to produce sex cells needed for reproduction

It stops the body from growing
