Porque será que hay más alfalfa que conejos ?

Hay más alfalfas que conejos porque los zorros y otros depredadores están matando a la población de conejos. Como hay menos conejos porque mueren muy rápido, las alfalfas crecen cada vez más. Los conejos son probablemente los únicos que comen las alfalfas y como hay menos conejos, las alfalfas son libres de crecer.

Explanation:

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
