Explanation:
The identification is based primarily on the analysis of one or two regions of the ribosomal DNA: sequencing of the D1 / D2 domains of the 28S rRNA gene and / or of the ITS region (ITS1 and ITS2 intergenic spaces and that includes the 5.8S rRNA gene ). Its comparison with the sequences available in public databases allows the strains to be assigned to a specific species when the homology percentage of its sequences is greater than or equal to 99%.
Answer:
C.
Explanation:
Mendel observed that some traits that were visible in the phenotype of F2 offspring were not visible in those of the F1 generation, but he concluded the invisible traits were nonetheless present despite their not being expressed or visible. He hypothesised that some traits were able to cover or hide others and he called the former "dominant" and the latter "recessive" and concluded that when both traits were together in the same individuals, the dominant ones did not allow the recessive ones to be expressed, which could only become visible in the next generation in the individuals where the dominant traits were not present.
Answer:
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein
Answer:
Eardrum→Ossicles→Oval window→Endolymph→Perilymph
Explanation:
The Ear is the organ of hearing and in mammals balance. In mammals the ear is often described as having three parts- The outer ear, the middle ear and the inner ear. the outer ear consist of the pinna and ear canal. The middle ear include the lymphatic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contain structures which are key to several senses: The semi circular canal which enable balance and eye tracking when moving. The Utricle and saccule which enable balance when stationary and the cochlea which enable hearing.
To make this more simple because the definition is complex, cryptorchidism is basically <span>a condition in which one or both of the testes fail to descend from the abdomen into the scrotum. Hope this helped you!</span>
