Answer:
The correct answer will be option-The red and white flower alleles are co dominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
Buffers such as bicarbonate buffer, citrate buffer and phosphate buffer are important in living system. pH of blood is near to neutrality (7.4). If the pH of blood increases, these buffers help in maintaining the blood pH. Increase in blood pH leads to certain diseases such as alkalosis. This further leads to muscle spasm and respiratory diseases.
Bicarbonate buffer helps to maintain the blood pH if it falls towards acidic range or increases towards alkalinity. It helps in decreasing acidity and increasing alkalinity by forming carbon dioxide gas. Increase in blood pH towards alkalinity is also maintained by excreting the bicarbonates into the urine. Similar action is also seen in case of phosphate buffer and citrate buffer.
Answer: If these buffers are not present in a living system then the change of pH cannot be altered or put back to normal. These buffers help to maintain the pH of the living system so that cells can work properly.
