Total questions: 25
1.
What happens immediately after fertilization in humans?
The zygote attaches to the ovary.
The embryo is formed.
The zygote undergoes division.
The zygote forms gametes.
None
2.
Which of the following statements is true about viviparous animals?

They give birth to live young ones.
Their young ones develop inside the egg outside the body.
They reproduce asexually.
None
3.
Which of the following correctly describes binary fission?
A new organism develops from an outgrowth.
A single parent reproduces by forming spores.
Fragments of an organism develop into new individuals.
An organism divides into two equal parts.
None
4.
Which of the following species undergoes internal fertilization?
Fish
Frog
Bird
Amphibians
None
5.
In sexual reproduction, the role of the male gamete is to:
Fertilize the egg
Develop into an embryo
Produce hormones
Grow into a new individual
None
6.
Which of the following is an advantage of internal fertilization over external fertilization?
Fewer offspring are produced.
The developing embryo is better protected.
The process requires less energy.
The chances of fertilization are lower.
None
7.
What is the role of the ovary in the female reproductive system?
To produce sperm
To produce eggs
To support embryo development
To form the zygote
None
8.
Planaria can reproduce by regeneration, a form of:
Fragmentation
Binary fission
Budding
Spore formation
None
9.
After fertilization, the zygote develops into:
A sperm
An embryo
An egg
A gamete
None
10.
A major difference between sexual and asexual reproduction is that:
Sexual reproduction involves two parents, while asexual reproduction involves one.
Asexual reproduction involves gametes, while sexual reproduction does not.
Offspring from asexual reproduction show more variation than those from sexual reproduction.
Sexual reproduction always produces identical offspring.
None
11.
In amphibians like frogs, fertilization occurs:

In the fallopian tube
Externally
Inside the uterus
None
12.
In which part of the female reproductive system does fertilization usually occur?
Ovary
Uterus
Vagina
Fallopian tube
None
13.
Ovulation in human females refers to the release of:
Sperm from the testes
An egg from the ovary
A zygote from the uterus
An embryo from the fallopian tube
None
14.
Which of the following is NOT a part of the male reproductive system?
Testes
Uterus
Sperm duct
Penis
None
15.
Hydra reproduces by budding. What is the initial step in this process?
Division of the parent into two parts
Formation of a bud on the parent body
Fragmentation of the parent
Spore release from the parent body
None
16.
Which of the following is a characteristic of asexual reproduction?
Offspring are genetically identical to the parent.
Two parents contribute to the offspring.
It requires the fusion of male and female gametes.
It involves internal fertilization.
None
17.

Vagina
Uterus
None

Frog
Whale
Salmon
Sea Urchin
None
24.
Which of the following statements about budding in yeast is true?
The parent yeast cell divides equally into two.
The parent cell forms multiple buds simultaneously.
Yeast undergoes binary fission to reproduce.
The bud develops into a new yeast cell and separates from the parent.
None
25.
Amphibians like frogs use external fertilization. What is one disadvantage of this method?
There is a greater chance of offspring survival.
It requires fewer energy resources.
There is a higher risk of fertilization failure.
It provides better protection to the developing embryos.
