Williamson ether synthesis is an organic reaction, forming an ether from an organohalide anda deprotonated alcohol(alkoxide). It involves the reaction of an alkoxide ion with a primary alky halide via SN2 reaction. The reaction to form propoxypropane using Williamson reaction is as shown
CH3CH2CHONa + CH3CH2CH2Br = C2H5CH2-O-CH2C2H5 + NaBr
Sodium propoxide 1-Bromopropane 1- Propoxypropane
Answer: Option A
Explanation:
The heterozygous allele can be defined as the condition in which the organism has two different alleles of the gene.
It is represented as Rr, means a capital letter and a small letter. This hows that the organism has one dominant gene and one recessive gene in it.
This dominant and recessive condition decides the genotype and phenotype of organism.
Most earthquakes are caused by faulting of rock in Earth's crust.
Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

Survival of the strongest... an organisms strength does not affect the natural selection process. Natural selection is adapting the species to be able to better survive in its environment. In order to better survive, an organism does not to be strong. e.g. a plant is probably not a “strong” organism and natural selection doesn’t change that in most cases
