This is true. The nervous system produces chemicals that affect our body at a rapid pace and the effects are usually short term and are designed for situations that are out of the ordinary. The endocrine system works slower and in the long run and there's not that much rapid effect that happens in stressful situations that the endocrine system solves or resolves. The hormones produced by the endocrine system are a constant that keeps being produced and they balance our body functions.
Stabilizing selection is one classification of natural selection which results to decrease in genetic diversity and stabilization of population traits through time. The answer in 1 is B. The difference between directional selection can be from disruptive selection is the genetic variance shifts toward a new phenotype Answer in 2 is D.

He cross pollinated the pea plant with another pea plant that had a different feature. The point is that he CHOSE the plant himself with that specific feature, it was in his control.
The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2 which cause cancer.
- Therefore, a microarray assesses the quantity of mRNA transcripts in a sample, A genome-wide perspective of gene expression in cancer can be obtained since thousands of gene fragments can be found on an array.
- The idea behind microarrays is that sequences that are complimentary to one another will bind to one another.
- Restrictions endonucleases fragment the unidentified DNA molecules, which are then labeled with fluorescent dyes.
- These are then given a chance to interact with DNA chip probes.
- Chemotherapy has a positive effect on one group while having a negative effect on the other.
- Gene-expression microarrays have shown that the two groups' gene-expression patterns differ.
