Answer:
Option D
Explanation:
From the phylogenetic tree, it can be deduced that the eukarya were derived from the shared common ancestors much later that the bacteria and archae. This separation was based on rRNA data. The tree also shows that the archae appears to be more closely related to eukaryotes than to other peokaryotes.
Answer:
The junction between two neurons is called a Synapse.
Because there all just flowers lol
Answer:
Duplication of the Dax1 is associated to equivocal sex determination on how XY mice develop ovaries and a female phenotype which comes from strong expression of the homologous gene (Ahch) in the first stages of gonadal (and adrenal) differentiation.
Explanation:
Dose-Sensitive Sex Reversal Locus on Chromosome X, Gene 1
, DAX1∗ (officially, nuclear receptor subfamily 0, group B, member 1; NR0B1) is a member of the nuclear hormone receptor superfamily of transcription factors that functions primarily as a transcriptional repressor.
Duplication of the DAX1/NROB1 locus is associated with male-to-female sex reversal, that is ambiguous external genital differentiation ranges.
One X chromosome and one Y chromosome in each diploid cell of their bodies differencite males from females, who typically have two X chromosomes but XX males that are SRY-positive have two X chromosomes, with one of them containing genetic material from the Y chromosome, making them phenotypically male but genetically female.
DAX1 protein may be directly or indirectly involved in gonadal regulation of hypothalamic-pituitary function.
