Answer;
The correct answer would be Rr.
In a monohybrid cross, the phenotype ratio of 3:1 is obtained only when both the parents are heterozygous for the trait.
In this condition, the heterozygous genotype would be Rr. The phenotype of both the parents would be round seeds (R) as the round is a dominant trait.
The cross of these parents would produce offspring with three types of genotypes RR, Rr, and rr in ratio 1:2:1.
Thus, the phenotypic ratio would come out to be 3 (round seed):1 (wrinkled seed).
Endorphins are a type of neuropeptides short strings of amino acids that are narrowly targeted to perform a specific job. For instance, endorphins specialize in reducing pain.
<u>Explanation:</u>
Endorphins are opiod neuropeptides that are produced by the central nervous system. They are natural pain killers that are produced by our body to reduce pain.
They are of 3 types namely, alpha endorphins, beta endorphins and gamma endorphins. All of these specifically bind to the opioid receptors inhibiting the communication of pain signals.

Chemistry is just about chemical reactions, properties of matter. Unless it is bio-chemistry which is just the mix of two.
