Answer:
The correct option is B. Rr × rr
Explanation:
To illustrate the results, lets make a cross between RR and rr.
r r
R Rr Rr
r rr rr
The results from the following punnet square show that there will be a 50% probability that the offsprings will have heterozygous genotype Rr and they will be round.
The results from the punnet square show that there will be a 50% probability that the offsprings will be recessive and hence will have wrinkled seeds.
Answer:
Plants and animals assimilate carbon-14 from carbon dioxide throughout their life. When they die, they stop exchanging carbon with the biosphere and their carbon-14 content begins to decrease at a rate determined by the law of radioactive decay.
Radiocarbon dating is basically a method designed to measure residual radioactivity.
Explanation:
Carbon-14 is a weakly radioactive carbon isotope; It is also known as radiocarbon, and is an isotopic stopwatch.
Radiocarbon dating is only applicable to organic materials and some inorganic materials (not applicable to metals).
Proportional gas counting, liquid scintillation counting, and accelerator mass spectrometry are the three main methods of radiocarbon dating.
The radiocarbon, or carbon-14, is an isotope of the carbon element that is unstable and weakly radioactive. The stable isotopes are carbon-12 and carbon-13.
Carbon 14 is continuously formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen-14 atoms, rapidly oxidizing in the air to form carbon dioxide and entering the global carbon cycle.
Accelerator mass spectrometry (AMS) is a modern method of radiocarbon dating that is considered the most efficient way to measure the radiocarbon content of a sample. In this method, the content of carbon-14 is measured directly in relation to carbon-12 and carbon-13 present. The method does not take into account beta particles, but the number of carbon atoms present in the sample and the proportion of the isotopes.
The correct answer is oxidative phosphorylation.
Oxidative phosphorylation refers to the metabolic pathway in which cells utilize enzymes to dissociate nutrients, thus, discharging energy that is used to generate ATP. In the majority of eukaryotes, this occurs within the mitochondria.
Approximately all the aerobic species carry out the process of oxidative phosphorylation. This pathway is possibly so prevalent as it is a highly effective manner of discharging energy, in comparison to substitute fermentation procedures, like anaerobic glycolysis.
