Answer:
One allele is on one chromosome, and the other is in the same position (locus) on the homologous chromosome.
Explanation:
The genotype of an organism refers to the genetic makeup or complete set of genes. The genes control the trait of an organism and exist in an organism in their alternative form called alleles.
Since the alleles are the alternative form of a gene, therefore, they must be present at the same position called a locus.
These alleles are present on the homologous chromosome in which each homologous chromosome is contributed by each parent.
Therefore when the genotype is aa then a and a allele will be present on homologous chromosomes in the same position.
Thus, the selected option is correct.
For the first blank, it's cell membrane and the other blank is transport.

Explanation:
2. Organism are classified foe easy identification.
3.classification of living things includes 7 levels:
kingdom
Phylum
Classes,
Order
Families
Genus
Species .
4.Organisms are classified into domains according to their characteristics features,habitat and mode of nutrition/ adaptation.
5.These organisms are classified together because they are made up of eukaryotic cells. Characteristics like structure, function, and method of reproduction further classify the organisms into smaller groups called kingdoms. The three domains are further divided into six Kingdoms.
6.Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.
