RNA world hypothesis

number of breaths also decreased. The mean of the average number of breaths is 69.24. The number of breaths in the study ranged from 16 to 135 breaths per minute. The null hypothesis, that the temperature of the water has no effect on the number of breaths per minute, can be rejected. The results support the alternative hypothesis. The control fish number of breaths per minutes remained constant in the study. Goldfish are ectotherms animals; the goldfish body temperature depends on the…

(Conservation Commission of Missouri, 2015). This immense variety of environments corresponds with a variety of light sources, colors, frequencies and intensities. The relation of this experiment to the Planarian’s living conditions correlates to the hypothesis tested in this experiment. If light has a higher frequency it is predicted the Planarian will travel the distance of the field diameter quicker, and on the reverse, when a light with a lower frequency is present the Planarian’s movement…

“ring” like bells（1）, not all of them endless displays of wildflowers (2), change into different colors, sometimes appears as veins of brown and red throughout the rock, and how it forms are considered as the ringing rock’s four mystery natures from now and on. It was said ,Ringing Rocks Park that situated near the small Delaware River community of Upper Black Eddy possesses this “ringing” quality,was the largest boulder field in Pennsylvania . The ring human can hear is not the first sound, but…

explanation for something, one that can lead us to new hypothesis, which we may agree or disagree with the original one. A group of hypotheses comes together to form a conceptual framework. As sufficient data and evidence are gathered to support a hypothesis, it becomes a working hypothesis, which is a milestone on the way to becoming a theory. Though hypotheses and theories are often confused, theories are the result of a tested hypothesis. While hypotheses are ideas, theories explain…

into each 12-L cages, with this relatively low density to avoid effects of crowding on longevity and mating performance. All cages were of clear plastic with a mesh-covered window (ca. 80cm2) for ventilation. No calling, courting, or mating were observed in cages prior to separating the sexes. A L12:D12 h photoperiod was maintained, with flies also experiencing a simulated dawn and dusk as the lights ramped up and down through an additional 1 h at the beginning and end of the light phase. 2.4.2…

times 20 seconds and 80 seconds are above the trend line and 40 secs and 60 secs are below the trend line. This therefore makes it a weak correlation, as there is no significant trend that can be seen that shows it is a positive trend line. Our hypothesis of our experiment was that the longer hair is exposed to heat the tensile strength of the hair would decrease. However, after conducting the experiment, results show otherwise. There has been one study that shows heat does increase the…

significantly faster reaction time than the ‘no caffeine group’ and the 100mg caffeine group (group 1). However, the ‘no caffeine group’ had a slight faster reaction than the 100mg caffeine group (group 1) Discussion The results do not support the hypothesis that reaction time will be faster amongst treatment group participants was not supported. The mean score of treatment group (100%) was higher than control group, which indicates that participants who consumed caffeine actually took longer…

The hypothesis for Experiment A was that each bacterium that was observed in this experiment possesses different characteristics, such as, different sizes, color, shapes, and even purposes. The reasons for this hypothesis is because, as the bacterium were being observed, it was recorded how one is uniquely different than the other. Each structure allows the bacterium to carry out different functions. However, some bacteria may occur more than once, or have a trait in common relating to another…

Discussion: In sample, B there was 16% salt, which is unnaturally higher than the global average of 3.5%. When I asked about the reason of this, I found that the water was artificially created. This was also the case of Sample, A which had 9% of salt. That is about 3x the amount of salt from the global average. All though this is not an experiment with data, that we can apply to real life, it was still great fun to do the experiment and the lessons I learnt will stick with me for a long time.…

method is used by every scientist around the world. There are five steps composed of the method, using the method you can go in order. After you discover a problem, you need to clearly state what the problem is. The first step of the scientific method is to understand the problem you have came up with and think of solutions to the problem. The next step to the method is to gather information about the problem so that you can develop an experiment or an hypothesis. In the article by authors David…
