  4. Offspring is diseased.

C Correct answer
Explanation

  • Sexual reproduction is a form of reproduction which involves the fusion of male and female gametes to form a zygote in a process called fertilization. Their looks are not exactly like their parents. 
  • In sexual reproduction, there is increased variation in the population giving the species a better chance of survival in changing conditions. The offsprings are often more vigorous and flamboyant, meaning they go to great lengths to find a mate.

Thus, the correct answer is option C.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The fertilization which takes place inside the female's body is called internal fertilization, hen shows internal fertilization.
The fertilization which takes outside the female's body is called external fertilization as in the case of frogs.
Sperm is the male reproductive cell or the male gamete.
Ovum is the female reproductive cell or the female gamete.
Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud due to the cell division at that particular site as in case of hydra.
Binary fission is a form of asexual reproduction used by all prokaryotes (including amoeba) where the cell divides into two nearly equal-sized daughter cells.
A zygote is a diploid cell that is formed by the fusion of male and female gamete. So, the fertilized egg is the zygote.
Thus, the correct answer is option C.

Which of the following plants reproduce without forming seeds?

  1. Mango

  2. Sugarcane

  3. Rose

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Seed is the product of ripened ovule after fertilization by pollen grains. These seeds further grow into a new plant. Some plants are reproduced without forming seeds but through the asexual reproduction. New sugarcane plants are produced from a mature sugarcane stem, rose from branch and potato from another potato. 

So the correct option is "Sugar cane and Rose".

Which of the following is the mode of asexual reproduction?

  1. Budding

  2. Spore formation

  3. Binary fission

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Asexual reproduction is a mode of reproduction in which, a new offspring is produced from a single parent. Some of the types of asexual reproductions are binary fission (e.g. Amoeba, bacteria), budding (e.g. Hydra), fragmentation (e.g. Planaria), spore formation (e.g. ferns) and vegetative propagation (e.g. Onion).
So, the correct answer is 'All of the above'.

Meiosis is a must in asexual reproduction.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Meiosis does not occur during asexual reproduction. Meiosis is the process of producing gametes which is occur in sexual reproduction. On the other hand, mitosis is simply the process of cell division in asexual reproduction. This is the process that animals are going through during regeneration. 

So, the correct option is 'False'.
