Random orientation of homologous pairs of chromosomes during meiosis I results in alternative arrangements that contribute to genetic variation in offspring. This is called "independent assortment".
<u>Explanation:</u>
The sets of homologous chromosomes, also recognized as bivalents or tetrads, align along the metaphase plate in a random order in metaphase I of meiosis I. Another way for cells to incorporate genetic variation is by spontaneous orientation. Mendel's independent assortment law stipulates that, independently of one another, the alleles of two or more different genes are sorted into gamets.
In other terms, for one gene, the allele that a gamete receives does not affect the allele that is obtained for another.Genetic recombination (by random segregation) and crossing over during meiosis creates daughter cells each containing different combinations of maternally and paternally coded genes.

Answer:
In three domain system Eukarya includes organisms from more than one kingdom
Explanation:
Of the biological taxonomy, domain is one of the rankings that keeps living beings organized. It is the highest ranking of taxonomy. Eukarya is the domain that contains organisms that are eukaryotic. These organisms has cells that has membrane bound organelles and a nucleus in it.
This domain includes more than three kingdoms. These domains are- Animalia, Fungi, Plantae and Protists. The organelles that belonged to this domain are called Eukaryotes.
In many regions, wetlands have been filled in so as to be able to use the land for farming. Wetlands are vital for reducing the intensity of floods, as they tend to hold back some of the water. Without wetlands, flood will tend to wash increased sediment and pollutants into the ocean, which can have a detrimental effect on marine life. Coastal developments can also have a negative effect on marine life. The removal or moving of beach sand is in particular damaging to intertidal organisms that depend on specific coastal environments, and rocky shores can be smothered by sand, whereas sand environments can change into bare rocky environments. Impounding of rivers and reduced river flow can result in estuaries becoming closed. Many marine organisms, such as fish, depend on estuaries as nursery areas where they lay their eggs. Reduced opening of estuaries means that many fish species cannot reproduce. Built harbours result in changed currents and alteration of the sea floor, which also disrupts marine ecosystems.
