Hydrogen peroxide is a natural byproduct of cellular metabolism in the human body. This product can be considered a free radical.
<h3>What is free radical?</h3>
A free radical may be described as any molecular species able to impartial life that consists of an unpaired electron in an atomic orbital. The presence of unpaired electron effects in sure not unusualplace homes which can be shared via way of means of maximum radicals. Many radicals are volatile and especially reactive.
These free radicals were recommended to be chargeable for reperfusion-triggered cardiac lovely and reperfusion-triggered arrhythmia. Hydrogen peroxide (H2O2) is frequently used as an experimental supply of oxygen-derived unfastened radicals.

<u>Answer</u>: Option A) cc
<u>Explanation</u>:
- For a given gene, there are 2 or more alternative forms present, and they are known as alleles.
- The alleles are of two types - <em>dominant and recessive.</em>
- The <em>dominant</em> allele is the one which expresses itself in both heterozygous and homozygous condition in the phenotype.
- The <em>recessive</em> allele is the one which is only able to express itself in homozygous condition.
- Since, the right thumb over left allele c is recessive, the person who crosses <em>right thumb over left must be a homozygote, and hence his genotype should be cc.</em>
Lowest temperatures would be D) 4 because lower pressure at higher altitudes causes the temperature to be colder on top of a mountain than at sea level.
