Answer:
Homologous structures have the same ancestry, but may no longer serve the same function. For example, the bones that make up human fingers were inherited from an ancestor that's shared by all mammals.
The interphase is the stage, in which the cell is not dividing. Teh genetic material in this stage is present as chromatin and the nuclear envelop remains intact, making the appearance as a darkly stained center. the nucleolus is also visible.
The prophase is the first stage of the mitosis, at this stage the genetic material starts condensing. the nucleolus starts fading away due to its degradation. the genetic material appears condensed and starts taking the shape of the chromosomes. The nuclear envelope is degraded, which makes the visibility of the chromosome easier.
Answer:
organisms living in a particular area
A hypothetical collection of all the possible alleles in a population gene pool . Thus correct option (C).
A gene pool is the collection of all the genes (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.
Primary gene pool, GP-1 is another name for it. The crop species itself, as well as its cultivated races and any wild or weedy spontaneous races are all included in the main gene pool, which is akin to a biological species in and of itself.
All the genes present in a population make up the gene pool. Any population might be included here, including frogs in a pond, trees in a forest, or residents of a town.

Tundra soils are generally frozen and are categorized as Gelisols. And in order to be a Gelisol, permafrost must be within 100cm of the soil surface.
