Answer:
SRY
Explanation:
Sex determination in mammals including humans is genetically and hormonally controlled.
Genetically gonadal sex determination is mediated by a gene called SRY. This gene is known as the mammalian Y-chromosomal testis-determining gene. It induces sex determination in males.
Recent studies revealed that SRY plays an important role in inducing Sertoli cells differentiation. The Sertoli cells, in turn, guide testis formation.
Therefore, in males, differentiation of testis is switched on by expression of the Y-linked SRY gene.
Answer:
5 minutes because its need to be a slightly thick.
true because they are driven by the ATP made by the light-dependent reactions. Both systems shut down in the dark. The light-independent reactions can last a little longer if there is ATP remaining in the chloroplast.
The type of organism is r-strategists include insects, mice, and bacteria, Therefore, the newly discovered animal
- r-strategists are those who thrive in predictable environments but compete for high-quality resources whereas r-strategists are those who tolerate unpredictable conditions by using a wide variety of resources
- r-strategists is typically reproduce once, but greater allocation to reproduction than growth results in large numbers of offspring
- r-strategists reproduce more than once but greater allocation to growth than reproduction results in fewer offspring
- r-strategists have short life span, density-independent mortality, typical of a type III survivorship curve
- r-strategists have long life span, density-dependent mortality, typical of a type I or II survivorship curve
