Answer:
Hoy en día, podemos incorporar nuevos genes de una especie en una especie completamente no relacionada a través de la ingeniería genética, optimizando el rendimiento agrícola.
A. Natural Selection. This is because the weeds that are not resistant to it die out before they can reproduce, but the resistant ones grow to maturity and then reproduce, passing down the resistance gene. Over time, the resistance gene would become a normal thing in weeds, while the non-resistant gene would not exist anyone, since the gene could not be passed on.
Answer:
the answer is B
Explanation:
because pangaea was a super continent
Genetically modified crops are genetically engineered such that a desired trait is enhanced or reproduced to appear in every offspring. Genetically engineered corn has been engineered to resist pests and herbicides; thus, we have more yield and many people especially in the low class society can afford. A disadvantage, yet is still a debate, is that genetically engineered crops such as corn, has toxic effects to internal organs such as our liver, a vital internal organ.
