is added, it turns yellow. When more O2 is added, it turns blue.

Bromothymol blue is an indicator for weak acids and bases.It is used to observe photosynthetic acvtivities and for respiratory indication.

Blue Bromothymol indicator will turn to green then to yellow when CO2 is added.When O2 is added, no effect is noticed in the Blue Bromothymol because Oxygen doesnot affect the pH.

In a summary, the color indication follows;

  • Yellow-to indicate acidic
  • Green-for neutral solutions
  • Blue-for alkaline solutions.

Black_prince [1.1K]

The statement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.

<h3>What are homologous chromosomes?</h3>

Homologous chromosomes are set of chromosomes that possess similar but non-identical genes.

Homologous chromosomes are from each parent of an organism i.e. male and female parent.

The homologous chromosomes is responsible for the diploid state of an organism, however, it becomes separated during the anaphase 1 stage of meiosis.

Therefore, the satement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.
