Answer:
Base pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structures possible. Base pairs themselves are formed from bases, which are complementary nitrogen-rich organic compounds known as purines or pyrimidines.

Explanation:
The phenotypic ratio in this case is 9:3:3:1.
<h3>
What is phenotypic ratio?</h3>
- A phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another.
- The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.
- A test cross is a technique used in genetics to investigate and collect potential genotypes and traits of offspring of organisms. An organism's genotype is its genetic make-up; it lists the alleles and genes that the particular organism possesses.
- The expression of genes and alleles in observable traits is referred to as the phenotype. Eye color, height, and even hair texture are examples of phenotypes.

Question:
Two pea plants are crossed. Both are heterozygous for purple blossom color, while one is homozygous for being short and the other is heterozygous for being tall. In pea plants, tall is dominant to short, and purple flowers are dominant to white. Find the phenotypic ratio.
Answer;
-White light and pure energy
-solar energy.
Explanation;
The sun is the source of all energy in the earth.
The sun energy is channeled to the biosphere through the process of photosynthesis in which solar energy from sunlight is converted to chemical energy.
The chemical energy is then used or stored by plants inform of starch. This chemical energy is ten passed to other organisms (heterotrophs) when they feed on the plants.
