Answer:
It allows information to go from one neuron to another through neurotransmitters.
The measurements taken by Jay are least likely to contain random errors.
When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.
Getting the probability for each event can easily be done using Punnett Square (say, Hh x Hh for the couple since they are both carriers of the disease). Doing so will result to: 0.25 probability of an offspring not having the disease and is not a carrier of the gene, 0.50 probability of an offspring not having the disease and is a carrier of the gene, and a 0.25 probability of an offspring having the disease. The probability of these events apply to each offspring, and will not depend on how many children they want to have. This means each offspring has a 0.25-0.50-0.25 chance of not being a carrier, being a carrier, and having the disease, respectively.
Answer:
D) Competition between organisms
Explanation:
Random mating between organisms, absence of any factor of evolution (mutation, recombination, gene flow, migration etc.) and a large population size serve to maintain the allele frequency and thereby the phenotype frequency over generations. However, competition between organisms for any natural resource leads to natural selection of "better competing organisms" and increases their phenotype frequency in the population.
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.
