Bromothymol blue is an indicator that can be used to determine the effects photosynthesis and cellular respiration. As more CO2

is added, it turns yellow. When more O2 is added, it turns blue.
A plant is placed in water while a student blows bubbles into the water with bromothymol blue. The water turns yellow. After 15 minutes, the water returns to a blue-ish color.

How more O2 added, causing the water turn back to 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.

k0ka [10]

1. Genetics and environment influence the trait as it depends upon the adaptation made according to availability and environment.

2. Traits are passed onto either parents after fertilization when 2 genes from either parent is received.

3. Dominant trait is responsible for the phenotype of the individual.

4. The expression of gene is seen by the phenotype expressed depending upon the environmental factors.

Explanation:

The food preferences are based on the traits adapted over the time for digestion and method of eating due to natural selection. The occurrence of beneficial trait for digestion become common in the population as these traits are transferred for better survival and evolution.

The traits in an organism is passed on from parents. During fertilization one allele from each parent is passed onto the progeny. 2 alleles together are called gene. In the process of meiosis only one chromosome is present in germ cell hence no homologous chromosome thus only one allele for the trait is present in each parent.

The alleles of dominant trait mask the effect of recessive alleles during phenotype expression. According to law of complete Dominance the dominant trait gets expressed and recessive trait do not get expressed.

The temperature, external environment, chemicals, light factor, diet etc influences the expression of genes in certain organisms. The effect of these can be seen on the phenotype of the organism.
