Answer:

The heritability coefficient is a statistic that describes how much of the difference between people's intelligence scores can be explained by <u>differences in their genes.</u>

Explanation:

The heritability is that fraction of the phenotypic variations observed for a characteristic due to the genetic action or genetic variation, that is, the genetic differences that each of the people have or as the coefficient of additive genetics on the phenotypic variance. The heritability coefficient is expressed as a percentage or value from 0 to 1, going from the most absolute absence of hereditary weight of the phenotypic character to the total heritability of it.

Intelligence is a polygenic trait; in which several genes have genetic influence, that is, differences in intelligence coefficients between individuals may be due to genetic factors. So, the heritability; the percentage of its variability in a given population that can be attributed to variation in genes, can explain the difference between people's intelligence scores. Studies suggest, the half of the variation in intelligence test scores among individuals could be attributed to genetic variation.

They then examined the infected cells and found that they contained labeled DNA, Since the phage DNA entered the infected cell, which demonstrated that it makes sense that DNA is the phage's genetic material. A bacteriophage or a phage is a virus that infects and replicates within Bacteria and Archaea. Phages replicate within the bacterium following the injection of their genome into its cytoplasm.

The force that drives earthquake activity is
ikadub [295]
<h2>Answer:</h2>

The force is <u>plate tectonics</u>.

<h2>Explanation:</h2>

The lithosphere, which is the inflexible peripheral shell of a planet, is broken into structural plates. The Earth's lithosphere is made out of seven or eight significant plates (contingent upon how they are characterized) and numerous minor plates. Where the plates meet, their relative movement decides the sort of limit: focalized, unique, or change.

Seismic tremors, volcanic action, mountain-building, and maritime channel development happen along these plate limits. The general development of the plates normally runs from zero to 100 mm yearly.
