Answer:
Option (D)
Explanation:
Buffers are the chemicals (acid or base) that maintain the level of pH in the living organisms. Different types of buffers that are present in many organisms are bicarbonates ad bi-phosphates.
The phosphate buffer is comprised of inorganic phosphate (HPO₄²⁻) which can bind with free hydrogen when the level of pH is low or in a highly acidic condition. In case of an excessive pH condition or in a basic condition, the phosphates act as a buffer by releasing the hydrogen ions.
Thus, the correct answer is an option (D).
The frequency of recessive yellow beans resulting from a cross between two heterozygous plants is 25%.
<h3>What are recessive alleles?</h3>
Recessive alleles differ from dominant alleles in not being able to express themselves in heterozygotes. These alleles are only expressed in the phenotype if they are present in pairs, that is, they must be in homozygosity.
With this information, we can conclude that the frequency of recessive yellow beans resulting from a cross between two heterozygous plants is 25%.
