Significance of mimicry is
1 Attack (Offance)
2 Protection (Defence)
3 Both (1) \& (2)
4 Isolation
Explanation:
Mimicry occurs when a given species, resembles another for its own benefit. It may help a predator in capturing food (offense) or it can help a prey in avoiding capturing. So option A\&B are correct.

Mycorrhizae are the example of
1 Fungistasis
2 Amensalism
3 Antibiosis
4 Mutualism
Explanation:
Mutualism is an association of two species in which both species are benefitted. - Mycorrhiza is a mutualistic relationship between fungal hyphae and roots of higher plants. - The fungus helps in mineral nutrition absorption from the plants which they are associated and obtained in turn nutrients from plants. - Amensalism is an interaction between different species in which one species is harmed and other is neither benefitted nor harmed e.g. Penicillin killing bacteria. - Antibiosis it is an antagonistic association between two or more organism, in which one is adversely affected e.g. antibiosis includes the relationship between antibiotic and bacteria. - Fungistasis inhibits the growth of fungi.

The animals of cold countries have relatively shorter and poorly developed ears, eyes, hairs and other phenotypic characters. This known by which law?
1 Cope's Law
2 Dollo's Law
3 Allen's Law
4 Bergmann's Law
Explanation:
Allen's Law states that in a warm-blooded animals species having distinct geographic populations, the limbs, ears, and other appendages of the animals living in cold climates tend to be shorter than in animals of the same species living in warm climates. Cope's law states that there in a tendency for animals to increase in size during the long course of evolution Dollo's law states that evolution is irreversible Bergmann's law states that warm blooded animals become larger in the northern and colder parts of their range.

During adverse season, the therophytes survive by
1 rhizomes
2 seeds
3 bulbs
4 corms
Explanation:
Seeds are small embryonic plants enclosed in a covering called the seed coat, usually with some stored food. The therophytes are the plants that can survive unfavorable condition as seeds and germinate when condition are favorable. The therophytes are those plants that survive unfavorable condition as seeds and germinate when condition are favorable. The therophytes are those plants that survive the winter as a seed and complete their life cycle between the spring and autumn.
