Answer:
The variation might occur in the population that leads to the evolution of the species. This variation may occur due to natural selection, mutation or recombination.
The variation might change the genotype and allelic frequency of the population and might also change the phenotype of the individual in the population. The breeding adults of the left mouthed in 1981, 1987 and 1990 shows variation and was equally opposite phenotype which is more common in the population.
Cant you just look this stuff up
Answer:
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

<span>The special senses of sight and sound are detected by, special cells that transduce stimuli into electrical signals. In the visual system, sensory cells in the retina convert the physical energy of light signals into electrical impulses that travel to the brain.</span>
Answer:
Fermentation
Explanation:
Fermentation is a catabolic, anaerobic process, which is not usually accompanied by electronic transport and whose final product is an organic compound. Yeasts are unicellular bodies (generally spherical in shape) with a size of around 2 to 4 μm and that are naturally present in some products such as fruits, cereals and vegetables. They are what are called: facultative anaerobic organisms, that is, they can develop their biological functions without oxygen. Yeasts carry out alcoholic fermentation. Its biological purpose is to provide anaerobic energy to unicellular microorganisms (yeasts) in the absence of oxygen, to dissociate glucose molecules and obtain the energy necessary to survive, producing alcohol and CO2 as fermentation waste.
