This type of placenta is found in humans beings, guinea pigs, rabbits, mice and rats.

It originates from the hypanthodium inflorescence. After fertilisation, the receptacle becomes thick and fleshy. The most prominent example is ficus.

It is a simple fleshy fruit. It originates from a syncarpous inferior ovary having axile placentation. The most prominent examples are citrus like orange and lemon.

It is a simple, dry indehiscent fruit having wings to help in dispersal. The most prominent examples are Acer and Dipterocarpus.

He was a German physiologist. He is famed for the development of cell theory, the discovery of Schwann cells in the peripheral nervous system, and the discovery and study of pepsin.

Physiological dormancy inhibits embryo growth and seed germination until chemical changes take place. It is an endogenous dormancy.

It is a manganese-containing enzyme being final enzyme of the urea cycle.

It is a simple, dry, indehiscent fruit originating from monocarpellary ovary with a single ovule. The most prominent examples are maize, rice and wheat.

It is defined as the lack of symptoms of aging in an organism. Particularly negligibly senescent animals do not have measurable reductions in their reproductive capability with age.

Here the flower is pollinated by pollen from another flower on the same plant. It favours self pollination.

It describes type of flowers. A chasmogamous flower opens and exposes the stamens and styles to the environment.

In this type of placentation, there exits only one prolongated placenta on one side of the ovary with simple carple.

It is the pollination done by snails. The prominent examples are cobra plant, arisaema and some arum bulbs.

Emmigration is the permanent movement of individuals of same species out of the local population due to considerable reasons such as lack of food, scarcity of space (over crowding), etc. It decreases the size of local population.

Similar populations of a species amusing different geographical areas are called sister populations.

Here the zones of two diverging populations are separate but do overlap. There is only partial separation afforded by geographical parameters.

It is the period of slow increase in the population.

No, the male midwife toad carry their eggs on thighs (hind limbs).

Some animals are 'polygamous', i.e. a single male keep a group of females and the male may copulate with any of these females during the breeding season. Examples: Walruses, deer, zebras, seals, etc.

It is just the reverse statement the size of home range varies. It can be as small as only a few metres (as in forest mouse) to several thousand square kilometres (as in African hunting dogs).

It is the only wrong statement. The nature of community is determined by only a few species called dominants and each community develops as a result of a directional change called succession. 

It is defined as the development of a bare area without any form of life. It is caused by soil erosion, landslide, earthquake, etc.

In a food chain, omnivores occupy more than one trophic level and some organisms grab different trophic positions in different food chains.

Secondary carnivores constitute the organisms, which eat the primary carnivores. The most prominent examples are wolf, peacock, owl, etc.

Secondary dormancy occurs in some non-dormant and post dormant seeds that are exposed to conditions that are not favorable for germination, like high temperatures. It is caused by conditions that occur after the seed has been dispersed.
