Which statement is NOT correct?
aliina [53]

Answer: a. Heritability research is able to identify genes for particular behavior patterns.

Explanation:

Heritability is the ability of a trait to move from one generation to another. Heritability, sum of phenotypic (observable) variability that is due to human genetic variations in a population.

Heritability, in a general sense, is the ratio of variability for a trait or character in a population due to variations between genotypes and the overall phenotypic variation.

Hence, as genes identification is are the basis of heritability research, option "a" is incorrect.

Based on the location of the flagellum what function does it serve
Pepsi [2]
<span>The filament of a flagellum rotates in a kind of sinusoidal motion, resembling a ship’s propeller or a corkscrew. Since the flagellum pushes instead of pulls, it is located at the rear of the microorganism. If there is more than one, they may act as a bundle. The direction of rotation determines the path of the microorganism. Flagella also serve as sensors, particularly for the detection of moisture.</span>

ipn [44]

Answer:

The correct answer is ''METAPHASE I.''      

Explanation:

Metaphase I is the stage in which chromosomal studies are generally performed, because its morphology is very clear. The chromosomes, moved by the mitotic spindle, are placed in the center, between the two asters and form the so-called metaphase plate, in which the chromosomes are positioned in such a way that the kinetochore of each sister chromatid are oriented towards the opposite poles. Keeping chromosomes on the cell equator implies a balance between the forces of the microtubules that tend to move the kinetochores toward opposite poles, so positioning them in the center involves a great deal of energy.In each kinetochore, between 20-30 microtubules can be anchored, which exert traction force towards the pole from which they come, so the metaphase plate is maintained by the balance between the opposite forces of the poles on the chromosomes, which hold their sister chromatids by centromeric cohesin.
