needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Answer:
True,Every chemical reaction obeys the law of conservation of mass.
Answer:
40 in tail and 20 in egg cells.
Explanation:
If a horse has 40 chromosomes in its heart cells so there will be 40 number of chromosomes in its tail cells and 20 number of chromosomes in its egg cells because tail is also a part of body where mitosis type of cell division occurs means there is diploid number of chromosomes, while on the other hand, egg cells are the reproductive part where meiosis type of cell division occur in which haploid number of chromosomes are present.
In terms of biodiversity, islands are special locations that contain a range of creatures and ecosystems for both native and endangered biodiversity. Endemism is typical of many islands. Thus islands are regarded as hot spots for biodiversity from a regional biodiversity viewpoint. In a collective portion of a basic land ecosystem it is much simpler to conserve species diversity than by shielding only one region of an archipelago.
Since every island has a specific variety of plants and animals, it is important that conservationists preserve the entire island chain. Thus allow the sources of food to differ from island to island in an archipelago. The type of producer originated in an island and then the type of consumers consuming it differ from island to island due to huge variety of and different adaptations of organisms.
