Answer:
solids are more tightly packed together (the molecules) than liquid or gas so it allows it to travel through vetter/faster
Speciation is the adaptive divergence and gradual that leads to two different species.
Reproductive isolation results in speciation when the processes of evolutionary mechanisms, physiological and behaviours are collected.
Mechanism of reproductive isolation helps in preventing members of different species from producing offsprings. A zoologist is a classified way of reproductive isolation whereby it(zoologist) is classified to the mechanism of reproductive isolation into two categories
(i) Pre-zygotic. This one acts before fertilization or before mating when it comes to animals.
(ii) Post-zygotic. It acts after fertilization.
The mechanisms appear I species which are genetically controlled and whose geographic distribution overlaps or are separated.
The term organic, as related to compounds, would be best defined as a compound that contains chain of carbon and hydrogen atoms which are bonded covalently. Common other atoms that could be included are hydrogen, nitrogen and oxygen.
