Sperms are unicelled and they are sex cells produced from testes in male individual.(b) A new human individual develops from a cell called gametes - False
A new individual is developed not from single gamete but from two gametes. A offspring is produced by fertilisation process where fusion of egg and sperm takes place.(c) Egg laid after fertilisation is made up of a single cell - True
During fertilisation process, the fusion form zygote which is single celled. It is later, divided to produce embryo.(d) A zygote is formed as a result of fertilisation - True
Yes, the fusion of male and female gamete produces zygote. This process of fusion is called fertilisation.(e) External fertilisation takes place in frog - True
In this type of fertilisation, the egg and sperm are fused outside the body of animal.(f) An embryo is made up of a single cell - False
During fertilisation, the zygotes divides into embryo. It is mutlicelled.(g) Oviparous animals give birth to young ones - False
The embryonic development takes inside the body of mother is viviparous animals and does not takes place inside body of mother in oviparous animals.(h) Internal fertilisation takes place in hens - True.
The zygote of hen develop into embryo and formed as egg. Egg is laid and chick is produced from laid egg.(i) The hens give birth to chicks like human beings give birth to babies - False
No, hen is a fowl and human is a mammal. Hen gives birth to chick through egg and humans give birth to babies directly.(j) Amoeba reproduces by budding - False
Amoeba undergoes reproduction through fission process.(k) Binary fission is a method of asexual reproduction - True
Yes, binary fission is a process of division of a parent cell into two daughter cells. The daughter cells are identical to parent cells.(l) Fertilisation is necessary in asexual reproduction - False
Fertilisation is a process of fusion of male and female gametes (two cells). But in asexual reproduction, the children cells are produced from a parent cell.(m) Cloning is a sexual reproduction method in mammals - False
Cloning is a natural or artificial process of production of genetically identical individuals.

1)Oviparous animals give birth to young ones. -False
2)A new human individual develops from a cell called gamete. -True
3)Amoebe reproduces by budding.- False
4)Fertilization is necessary even in asexual reproduction,-True
5)A zygote is formed as a result of fertilisation.
6)An embryo is made up of a single
Please mark my answer brainliest.
6. false - because it is reproduced by asexuals reproduction.
1st case we can produce sound in and vacuum room
2 nd case we can produce sound in a normal room .
we observe that we cannot hear in the vacuum but we can hear sound in the normal room.
proves that sound needs medium.
