Answer:
the variability in neuroticism is due partly to genetic variability in the population.
Explanation:
In population genetics, heritability (h) is defined as the amount of the phenotypic variation attributable to genetic factors rather than environmental factors.
Mathematically, h is calculated by using the following equation: H2 = Vg/Vp, where Vg is the variation in genotype, while Vp is the variation in phenotype.
An H value close to zero (0) indicates a very low heritability (i.e., the phenotype depends on the environmental differences between individuals), while an H close to one (1) indicates very high heritability (i.e., the phenotype is firstly dependent on genetic factors).
Frequent inbreeding within a species can result in extinction of the species. The recurring set of available genes during reproduction allows for decreased genetic diversity.
Answer:
B) As seen from Earth, the Sun is the brightest star on the chart, and Barnard's Star is the dimmest
Explanation:
Among the given choices:
A) Of the stars listed, Proxima Centauri and Barnard's Star appear red because they burn the hottest.
This is not the correct answer because temperature of Barnard's star is 5000° F which is lowest in the data.
C) Small dwarf stars, like Proxima Centauri and Barnard's Star, do not burn as hot as medium dwarfs.
Proxima centauri being a small dwarf has a higher temperature than sun which is a medium dwarf.This shows that small dwarfs can burn hotter than medium dwarfs. So this option is not suitable.
D) Proxima Centauri and Barnard's Star are the closest because they are classified as "small dwarfs."
This is not correct choice because the data clearly states they are at greater distance.
So ,the correct choice is:
B) As seen from Earth, the Sun is the brightest star on the chart, and Barnard's Star is the dimmest.
Because: Sun is closest to the Earth and thus will appear the brightest as maximum light from it Reaches the Earth. Barnard's star is Farthest so less light reaches the Earth from it and it appears the dimmest.
