Question 1

1 / -0

Which of the following points is correct?

	Oviparous		Viviparous
1.	They lay eggs.	1	Give birth to young ones directly.
2.	Chances of survival of young ones are less.	2	Chances of survival of young ones are more.
3.	E.g. Whale and dolphins	3	E.g. Birds and frog

1, 3

2, 3

1, 2

All of above

Solution

1 and 2 are the correct distinguishing points between oviparous and viviparous animals. Oviparous animals lay eggs and in oviparous animals, chances of survival of young ones are less as the females lay eggs in the open environment. Viviparous animals give birth to young ones and the chances of survival of young ones are more because the embryo grows inside the mother's womb, so the protection is more.

3 is not correct because whales and dolphins are viviparous animals while frogs and birds are oviparous animals.

So, the correct answer is option C.

Question 2
1 / -0

Give the correct correlation.
Oviparous : _______ :: Viviparous : ______

A
Crow, Cat

B
Frog, Lizard

C
Dog, Cow

D
Crow, Frog

Solution

Crow, frog, lizard are oviparous animals whereas cat, dog and cow are viviparous animals.

So the correct option is Crow, Cat.

The correct option is A.
Question 3
1 / -0

Asexual reproduction takes place through budding in

A
Amoeba

B
Yeast

C
Plasmodium

D
Leishmania

Solution

Saccharomyces cerevisiae commonly known as yeast, reproduces both asexually as well as sexually. Yeast reproduce asexually through a process known as budding.
Question 4
1 / -0

Give an example of viviparous animals.

A
Human being

B
Frog

C
Butterfly

D
All of the above

Solution

Females in viviparous animals give birth to young ones. Mammals, like whales, sharks, mice, humans are examples of viviparous animals. Frog and butterfly are oviparous animals.

So, the correct answer is Human being.

The correct option is A.
Question 5
1 / -0

Animals which give birth to the young ones are called _______.

A
oviparous

B
viviparous

C
ovi-viviparous

D
None of these

Solution

Animals that give birth to their young ones are called viviparous. The young ones resemble their parents. Oviparous animals lay eggs while ovo-viviparous organisms produce eggs that develop and hatch inside the mother's body till they are fully developed and born alive. So, the correct answer is option B.
Question 6
1 / -0

Arrange the following steps in proper order

a) Formation of zygote
b) Formation of embryo
c) Fusion of male and female gamete
d) Implantation of embryo into uterus

A
a $$\rightarrow$$ c $$\rightarrow$$ d $$\rightarrow$$ a

B
a $$\rightarrow$$ b $$\rightarrow$$ c $$\rightarrow$$ d

C
c $$\rightarrow$$ a $$\rightarrow$$ b $$\rightarrow$$ d

D
d $$\rightarrow$$ c $$\rightarrow$$ b $$\rightarrow$$ a

Solution

1) Fertilization starts with the fusion of male gamete (sperm) and female gamete (zygote).
2) This fusion results in the formation of a zygote.
3) Zygote divided repeatedly to give rise ball of cells that forms embryo.
4) After the formation of embryo is gets embedded in the wall of uterus where it further forms the foetus so the correct order is in above steps.
Question 7
1 / -0

Animal which lay eggs are called _____

A
Vivparous

B
Oviparous

C
Both a and b

D
None of above

Solution

Oviparous animals can reproduce by laying eggs. This is how most fish, amphibians, reptiles, insects, and arachnids reproduce. All birds and monotremes also reproduce like this. But, viviparous animals are born as the live young individuals.

So the correct answer is oviparous.

The correct option is B.
Question 8
1 / -0

All are the types of plant stems except

A
Corm

B
Node

C
Rhizome

D
Tendril

E
Tuber

Solution

All the given options Corm, Rhizome, Tendril, and tuber are the modified stem parts but the node is the part where leaf get attaches to stem.
So the correct option is 'Node.'
Question 9
1 / -0

Which of the reproductive strategy is most effective in stable environment and abundant resources?

A
Sexual reproduction, with intense parental care and slow development

B
Sexual reproduction, with slight parental care and quick development

C
Parthenogenesis

D
All of the above

E
None of the above
Solution
- Parthenogenesis involves growth and development of embryo from an unfertilised egg cell.
- Parthenogenesis will result in offspring that are genetically similar and with stable environment and abundant resources all of them can survive.
- While, sexual reproduction results in offspring that are not identical and this variation leads to competition for resources.
So, the correct option is 'Parthenogenesis'.
Question 10
1 / -0

Cnidarians reproduce asexually by __________.

A
Multiple fission

B
Binary fission

C
Budding

D
Fragmentation

Solution

Cnidarians reproduce both sexually and asexually. Asexual reproductive is by lateral budding where as sexual is through gamete formation.
