Internal fertilization occurs in hens. Fertilized egg is enclosed in a protective shell covering in hen's body and is laid outside for development.
In frogs, fertilization and development of zygote both takes place outside of ir body, that is, external fertilization.

Vivipary is development of embryo inside body of mor, eventually leading to live birth.
Carnivorous are animals that feed on animal flesh.
Omnivorous are animals that feed on both plants and animals.
Ovipary is method of reproduction in which eggs are laid and embryos develop outside mor's body, each egg eventually hatching into a young animal.
So, correct answer is option D.

The reproductive cycle of non-primate females is called oestrous cycle. For example, in rats, horse etc. It can be divided into four phases proestrus, estrus, metestrus and diestrus. 

All given options Corm, Rhizome, Tendril, and tuber are modified stem parts but node is part where leaf get attaches to stem.

Sexual reproduction is basically process of formation of a zygote which is formed after fertilization of gametes. gametes are from 2 different parents. variations arise in sexual reproduction which is due to crossing over that takes place in meiosis.

 Answer:

Budding is common method of asexual reproduction in which cell division occurs at a particular site and an outgrowth is formed called as bud which leads to a new organism and detached from parent as y get matured. It is commonly exhibited by Hydra and Yeast.

Sexual reproduction is complex (long and energy consuming) process characterized by meiosis and fertilization which in turn add new genetic combination (i.e. new characters) to existing species. Genetic diversity serves as raw material for natural selection which favors characters that impart survival advantage to individuals. Accumulation of se adaptive characters over generation makes population better adapted to prevailing condition and imparts survival advantage.

Sexual reproduction, unlike asexual reproduction is a slow process. Since it is fusion of 2 opposite sex gametes, it produces variations better than parent. The time period varies from specie to specie.
