Answer:
Stabilizing selection results in a decrease of a population 's genetic variance when natural selection favors an average phenotype and selects against extreme variations. In directional selection, a population's genetic variance shifts toward a new phenotype when exposed to environmental changes.

what is NCF for nucleolus?
Answer:
The NCF and PAG are brainstem nuclei involved in a network mediating anti- and pro-nociception, as largely shown from animal data (Fields and Basbaum, 1999 for a review, [Porreca et al., 2002] and [Gebhart, 2004]). Human imaging studies have shown that the PAG and NCF are activated during visceral and somatic pain (Dunckley et al., 2005) and that the NCF plays a key role in the development of experimental secondary hyperalgesia via possible facilitatory pro-nociceptive mechanisms (Zambreanu et al., 2005). The NCF and PAG have been shown to be important in brainstem modulation of pain in humans (Zambreanu et al., 2005), and connections to these nuclei provide an anatomical basis for results of recent studies involving pain control and perception ( [Lorenz et al., 2003], [Valet et al., 2004] and [Wager et al., 2004]). The NCF has recently been shown to be critical for the generation of secondary hyperalgesia in humans

A man and a woman have three children, all males. What is the probability that their next child will be a girl?.
Given what we know, we can confirm that the couple in question has a 50% chance that their next child will be a girl.
Why are the odds 1/2 ?This has to do with the fact that each child that the couple has is an independent event. While it is true that it is unlikely for the same event to occur many times in succession, the previous events do not influence the outcome of the next child.
Therefore, given that a child can be either male or female when born, the couple in question has a perfect 50% chance for their next child to be a girl.

A population of white moths moves into an area dominated
by grey moths. How do you think the introduction of white moths will impact
the grey moths? Explain your answer
Answer:
During the industrial revolution in England, the soot from the coal burning factories started dominating the environment. The trees were also darkened as a result and the light-bodies moths that were able to blend with the light-coloured lichens and tree barks were in danger due to their predation by the birds. This lead to the rapid decrease in the light-colored moths. As a result, the moths got adapted to the blackened trees with their transformation into dark-coloured moths which Increased rapidly. This was because the allele for the dark-bodied moths is dominant and the allele for the light-bodied moths is recessive. Since birds would find and eat the light-bodied moths, dark-coloured moths increased as a result of natural selection. Thus, these moths with a favorable adaptation to the change in the environment were selected and they reproduced new offspring.

Which of the following would be the best method to increase the largemouth bass population in the Florida Everglades?
A. Move more largemouth bass into the Florida Everglades
B. Introduce a species of fish that will eat the oscars
C. Increase the food supply for both largemouth bass and the oscars

What does this mean in your own words?
The amount of carbon dioxide (CO2) in a solution is one of the many factors that determines the pH of water. As pH levels fluctuate during the day due to photosynthesis, respiration, and decomposition; the extremity of these changes depends on the alkalinity of the water which is influenced by CO2 levels. When CO2 levels increase in water, the pH level drops, which makes the water become more acidic.
