Answer:
From September 6th to October 3rd. 28 days.
Answer:
XnY
Explanation:
II-2 is a male so the genotype must have a Y in it. Majority of the other options do not have Y, so they are incorrect. Because the individual is male, the father has passed a Y chromosome, while the mother has passed an X chromosome. The X chromosome is Xn because the mother is hemolytic, which is a recessive trait. So both the mother's X chromosomes carry the hemophilia trait.
Genetic drift
- initially from same species however due to natural circumstances some of the species relocates resulting in them evolving based in surroundings hence the process of natural selection; the survival of the fittest
Genetic bottleneck
- due to a natural disaster or crisis a species almost becomes no existent resulting in the remaining organisms of such species to repopulate resulting in only the fittest organisms of that species surviving hence once again the process of natural selection
The greatest way to explain natural selection is Darwin in the Galapagos island with the finches; Darwin studied these birds and discovered based on geographical location the same species of bird had evolved as identified by the change in beak structure in order to scavenge for food. The best way to explain it is the survival of the fittest same with long neck giraffes all the short neck giraffes died off due to them not being able to reach the leaves to eat
Pre-frontal Cortex (PFC)
The PFC is often one of the last regions of the cerebral cortex to fully develop. It is the area of the brain most associated with executive function, logic, reason, and some anticipation of consequences.
Research estimates that most females' PFC is nearly fully developed by ages 16-21; however, males lag in this development of their PFC by an average of ages 19-24.
Thus, before legal age (18), minors (males > females) are more apt to partake in risk-taking behaviors.
Answer:
Chromosomes line at the center during metaphase, and spindle fibers are attached.
