It is taxis as taxis is movement characterized by light, heat, moisture, or chemicals while kinesis is movement that involves orientation.
Gametes are haploid cells, the haploid number is n = 23, and each parent could provide half of the centromeres. Hence, the fraction of a man’s gametes that contain centromeres inherited from the same parent is 1/2²³.
--------------------------------------
We know that the diploid number in humans is 2n=46. This means that the haploid number is n=23.
We need to know the fraction of a man’s gametes that contains centromers inherited from the the father or the mother.
A gamete has 23 chromosomes.
<em>Half of the centromers could be inherited by the </em><em>father (1/2)</em><em> and half by the </em><em>mother (1/2)</em><em>. </em>
<em />
So the fraction should be 1/2ⁿ = 1/2 ²³
- 1/2 because half of the centromers could be inherited by the father or the mother
- n because is the haploid number of chromsomes in the gamete ⇒ n = 23

Like many plants, most species of grass produce a bright pigment called chlorophyll. Chlorophyll absorbs blue light (high energy, short wavelengths) and red light (low energy, longer wavelengths) well, but mostly reflects green light, which accounts for your lawn's color
