Gel electrophoresis is the movement of charged particles in a fluid or gel under the influence of an electric field. Results of this technique can be interpreted to find out if someone carries a certain gene or not.
Answer:
rainfall, changes in water level, earthquakes
<span>Human skin color is a polygenic trait, which means that multiple gene loci (with different alleles) are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues.</span> <span> Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).</span>
Answer:
The correct answer would be Jenna’s cells are producing more lactic acid than Raul’s cells.
Workouts like sprints, bleachers, weight training et cetera come under the anaerobic zone of training.
They cause lack of oxygen in the muscles due to which muscles undergo lactic acid fermentation to produce energy (ATP).
Lactic acid fermentation converts one molecule of glucose into 2 molecules of lactic acid with a net gain of 2 ATP (as compared to 36-38 ATP produced in aerobic respiration).
Decreased efficiency in energy production leads to the utilization of more and more glucose or glycogen reserves of the muscles and lead to the accumulation of more and more lactic acid.
