The oxygen atoms undergo reduction, formally gaining electrons, while the carbon atoms undergo oxidation, losing electrons. Thus oxygen is the oxidizing agent and carbon is the reducing agent in this reaction.
Answer:
C. Evolution is a change of allele frequency from one generation to the next
Explanation:
Evolution is the gradual change that occurs to living organisms over successive generations. According to Charles Darwin, these changes aid in the adaptation of the species of an organism to their environment. In other words, it makes them better fit.
Charles Darwin further stated that since evolution is dependent on natural selection i.e selection of the best fit by environmental factors, the changes that the organism undergo are genetic. Hence, evolution is a change of allele frequency from one generation to the next.
Answer:
Genetic engineering he technique has been used in breeding crops and livestock to increase yields in food production, as well as to manufacture pharmaceuticals and industrial chemicals.
Explanation:
Genetic engineering or recombinant DNA technology introduces foreign genes into microbes, plant, and animals in order to express new characteristics.
Answer & Explanation:
Vision is simply the sense or ability of sight; the ability to see or the perception of light. Tapetum lucidum present in most fishes especially the nocturnal ones and sharks, is located behind the retina. It is a special eye structure whose function of which is to return rays of light that have escaped from the retina back to the retina to improve vision. This has enabled them to survive in an environment where light readily disappears due to depth.
