Over time plants and animals have developed defenses against being eaten. What are some examples of these defense mechanisms?
Mnenie [13.5K]

Answer:

The thorns on a rose bush.

The white coat of a snowshoe hare.

The speed of a gazelle.

Explanation:

Defense mechanisms are the adaptations and modifications in a living organism to counterattack or provide a defense in response. Some modification in the plant and the animals helps them to provide a counterattack to save themselves from the attack. The defensive function of the thorns in the roses helps them from being eaten or crushed. Snowshoe hares have furry feet that are large. The white fur helps them to camouflage during winter in the snow and be safe from the predators. Gazelle is an antelope found in South Africa that is able to make long jumps and make sharp turns while running and saving itself from the predators.

Explain how XY mice with a duplication of chromosome 1 develop<br> 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.
