The answer to your question is B
Answer is Homologous.
A diploid individual having two different alleles for a specific trait is called heterozygous. An allele is the alternative form of the same gene. The cells in diploid organisms contain sets of homologous chromosomes, which are paired chromosomes. Each chromosome of a homologous pair has the same genes on the same positions. Although homologous chromosomes have the same genes, they may have different alleles for those genes.
Example: The gene for seed color trait in a pea plant exists in pair. One gene or allele for yellow seed (R) and the other for green seed color (r). A heterozygous plant would contain alleles for seed color (Rr). Gene R is present one chromosome and its allele (r) is present on the other chromosome of the homologous pair.
Answer:
Cyclines in phase s double their DNA.
Explanation: Hello, In this phase the cyclin doubles in a strictly regulated and conserved manner.
The bony labyrinth is a region of dense bone that surrounds and protects the membranous labyrinth.
Labyrinth is the name given to the inner ear. It is made up of a network of interconnecting sacs and canals. The inner ear is composed of two parts: bony labyrinth and membranous labyrinth. A vestibule, three semicircular canals, and a spirally wound cochlea make up the bony labyrinth. It is perilymph-filled.
The membranous labyrinth is encircled by the bony labyrinth. It includes the hearing and balance sensory receptors. The cochlear duct, saccule, and utricle and three semicircular ducts that make up the endolymph-filled membranous labyrinth. The cristae, an organ of corti, and the ampullaris maculae are examples of sensory receptors.
