Answer: All galaxies are moving further away from us due to the expansion of the universe that happened after the big bang
The liver plays an important role in the food digestion. The liver secretes bile juice which helps in the digestion of the fats. In the absence of digestion, this bile is stored in the gall bladder. The bile juice is the yellowish fluid, which aids in the digestion of fats (occurring in the small intestine) by emulsifying the fats molecules. the emulsification of these fat molecules is critical for their digestion, and absorption. Hence, the liver secretes bile juice and acts to emulsify the fat in the lumen of the small intestine.
Answer:
In meiosis I, the arrangement of any homologous chromosome along the center plane ( forgot the name for this) is independent of the arrangement of the other homologous chromosomes. There is thus equal probability for the chromosome to be in either of the two daughter cells after meiosis I. This is observed in meiosis 2 metaphase as well where the arrangement of each Sister chromatid about the ‘center plane’ is independent of each other. This independence observed during metaphase of meiosis I and meiosis II allows for chromatids to be in either gamete formed in equal probability, not affecting by other chromatids thus inheritance of one trait is not affected by the inheritance of another trait.
Answer:
Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.
Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.
Species diversity: Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.
Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.
Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.
Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.
Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.
