This is due to the fact that only homologous chromosomes would have identical genes located at identical sites on those chromosomes. Otherwise, there would be no connection between the alleles of various genes.
Although the genes and loci of the two members of the homologous pair are similar, the alleles may vary.For instance, both allele possess the genes responsible for the attribute of eye colour. While the one has alleles for the blue-eye trait, other has alleles for the brown-eye trait. The homologous chromosomes are said to be heterozygous in this instance since the alleles are different.
On the other hand, when both alleles for a gene that codes for the blue-eye phenotype are present, it is said to be homozygous.

We have that all of life is organized in 5 kingdoms. The animals and the plants are pretty straightforward; the first one contains most organisms that produce their own energy and the second one contains multicellular organisms that usually move. Fungi are a kingdom whose members are both multicellular and monocellular and they are eukaryotic. Protista are eukaryotic unicellular and Monera are prokaryotic unicellular. Most of the pathogens that we treat today are either fungi (athlete's foot) or are caused by bacteria which are contained in the kingdom of monera. A lot of protista can also be pathogens; a prime example is the disease of malaria whose cause is a protist. Viruses are also a big threat to health and are called pathogens but they do not constitute a kingdom (we do not classify them as alive). Hence, the three correct choices are Protista, Monera and Fungi.
Answer:
The process of science is a way of building knowledge about the universe — constructing new ideas that illuminate the world around us.
The seperation between periods and species alive in those time periods
Answer:
<u>d. the cells in primary cell cultures do not divide.</u>
A key difference between primary cell cultures and secondary cell lines is that<u> the cells in primary cell cultures do not divide.</u>
<u>hope</u><u> </u><u>it</u><u> </u><u>helped</u><u> </u><u>you</u><u> </u>
Explanation:
<em>The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.</em>
