Explanation:

Claspers of cartilaginous fishes (sharks) is one pair between the pelvic fins. Claspers are analogous to penis of human male both act as copulatory organ and transfer the sperm into female.

Which of the following animals give birth to young ones?

biology animal lore types of reproduction in animals oviparous and viviparous a study on animals butterfly and honey bee

  1. Ornithorhynchus and Echidna

  2. Macropus and Pteropus

  3. Balaenoptera and Homo sapiens

  4. Both (b) and (c)

Show answer
Correct Option: D
Explanation:

An animal that is viviparous gives birth to young ones. The embryos are raised with special organs in the parents as they develop, those supply nutrients to the growing embryos. Example -Homo sapiens (humans), Macropus (Kangaroo), Pteropus (Flying fox), Camelus (Camel), Delphinus (Common dolphin), Balaenoptera (Blue whale).

So, the correct option is 'Both (b) and (c)'.

Which of the following hormones controls metamorphosis in a frog?

biology butterfly and honey bee life cycle of a butterfly metamorphosis in frogs the life of a butterfly types of reproduction in animals oviparous and viviparous

  1. Adrenaline

  2. Insulin

  3. Oxytocin

  4. Thyroxine

Show answer
Correct Option: D
Explanation:

Metamorphosis includes the developmental changes during the life span of an organism. The thyroxine hormone released from the thyroid gland brings the developmental changes during the metamorphosis. Thyroxine regulates the metabolism of an organism.

So, the correct answer is option D.

(a) Zygote divides a number of times and forms a hollow ball-like structure called  (i). 

      It moves down and gets implanted in the uterus. It starts developing body parts and at this stage,          it is called (ii).

(b) (iii) is the period in life when a girl or a boy attains sexual maturity.

(c) Production of sex hormones is under the control of _(iv)_ gland.

(d) Metamorphosis in frog requires the presence of _(v)_ in water to produce thyroxine hormone.

Choose the correct option for any of the two blanks.

  1. (i) - Fetus, (iv) - Thymus

  2. (ii) - Embryo, (iv) - Pituitary

  3. (iii) - Adolescence , (v) - Calcium

  4. (ii) - Fetus , (iii) - Senescence

Show answer
Correct Option: B
Explanation:
  • The four introductory phases of embryonic advancement are the morula organize, 
  • the blastula arranges, the gastrula arranges and the neurula organizes.
  •  The front pituitary organ delivers the accompanying hormones and discharges them into the circulation system: adrenocorticotropic hormone, which animates the adrenal organs to emit steroid hormones.

So, the correct option is '(ii) - Embryo, (iv) - Pituitary'.

Match the following (w.r.t type of metamorphsis involved).

  2. a(i) , b(iii) , c(iv) , d(ii)

  3. a(ii), b(iii) , c(i) , d(iv)

  4. a(ii) , b(iv) , c(iii) , d(i)

Show answer
Correct Option: A
Explanation:

a) Paurometabolous metamorphosis is characterized by gradual development from the immature stage i.e nymph to the adult stage. Eg- grasshopper.

b) Hemimetabolous metamorphosis is known as incomplete metamorphosis as consists of three stages of development- egg, nymph and adult stage and does not have the pupal stage. Eg- the dragonfly.
c) Holometabolous metamorphosis is called complete metamorphosis as it consists of all the four stages of development- egg, nymph, pupa and adult stages. Eg- silkworm.
d) Ametabolous development refers to the developmental process in which the immature stages are very similar to the adults and no metamorphosis occurs. Eg- silverfish.
So, the correct answer is 'a(ii), b(iv), c(i), d(iii)'.

A tadpole develops into an adult frog by the process of

biology butterfly and honey bee life cycle of a butterfly metamorphosis in frogs the life of a butterfly types of reproduction in animals oviparous and viviparous

  1. Fertilization

  2. Metamorphosis

  3. Embedding

  4. Budding

Show answer
Correct Option: B
Explanation:
A. Fertilisation is the fusion of male and female gametes and results in the formation of zygote.
B. Metamorphosis is the process by which an organism undergoes various physical changes and transforms from immature adult or larval form into a mature adult.
C. Embedding means to get stuck on something.
D. Budding is a type of asexual reproduction in which the parent cell produces one or more bud like protuberances which detach from parent cell and grow into a new individual.
Hence, a tadpole develops into an adult frog by the process of metamorphosis as it is transforming from an immature adult into an adult frog. So, the correct answer is 'Metamorphosis'.

Caterpillar and maggots are

  1. Larvae

  2. Nymphs

  3. Adults

  4. Pupa

Show answer
Correct Option: A
Explanation:

A larva is a distinct juvenile form many animals undergo before metamorphosis into adults. Caterpillar is the common name for the larvae of members of the order Lepidoptera (the insect order comprising butterflies and moths). A maggot is the larva of a fly (order Diptera). 

So, the correct answer is option A.

Structure which remains unchanged, during metamorphosis of frog's tadpole is

  1. Lung

  2. Heart

  3. Brain

  4. Intestine

Show answer
Correct Option: C
Explanation:

The nervous system undergoes least changes during metamorphosis of frog's tadpole. Frog's nervous system once differentiated remains as such throughout life. However, the brain acquires its normal shape and size. 

Therefore, the correct answer is option C.
