A potentially fatal condition, characterized by the failure of the body's heat-regulating mechanisms, is:

1 answer:

3 0

It is Heat stroke. This is a form of hyperthermia in which the body temperature is elevated dramatically. It is a medical emergency and can be fatal if not promptly and properly treated. It is caused by an elevation in body temperature, often accompanied by dehydration. The symptoms include; confusion, the absence of sweating, agitation, disorientation, and coma. Most important measures to prevent heat stroke is to avoid becoming dehydrated and to avoid vigorous physical activities in hot and humid weather.

Explain how XY mice with a duplication of chromosome 1 develop ovaries and a female phenotype.

Dahasolnce [82]

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.

To help sort out those bacteria that have the vgp gene, scientists first attempt to grow the bacteria both in a medium with ampi

pshichka [43]

Answer:

Explanation:

bacteria with No Plasmid -----------------will grow ONLY in medium without ampicillin.

"nonrecombinant gene, recombinant plasmid with vgp gene,", recombinant plasmid but no vgp gene-----------------------will grow in both media".

it means Plasmid have ampicillin resistance gene. So if we use medium with ampicillin so it will allow the growth of only those bacterai which have transformed plasmid (containing amp resistance gene).

so having gene or not, recombinant or recombinant dosnt matter, all the other s will grow in both type of medium as far as plasmid is transformed in to it.

During meiosis, errors occur during chromosome replication. Which term describes the rearranging of genetic material between non

7nadin3 [17]

Answer:

The correct answer is: translocation.

Explanation:

Translocations are chromosomal abnormalities that are caused by an error that can occur during meiosis when a piece of a chromosome breaks off and it is attached to another chromosome that is not its homologous pair.

There are two types of translocations when taking into account if there were a loss or gain of genetic material, or if it weren't. The type of translocation where there's no loss or gain of genetic material is called balanced, since the information is still there but in a different location.
